Why? Focusing on work patterns or schedule templates does not address the primary purpose of the schedule, namely to match the coverage with the workload. Since most police departments don’t have steady work volumes, it’s essential that the schedule reflect this. The ideal schedule will produce higher coverage when the group is busiest and less coverage when it’s not.

So how do you accomplish that? Here’s an example of how I approach the design of police schedules.

Background

A small police department contacted me for help with their schedule. They had 15 officers and wanted to adopt 10-hour fixed shifts.

Hourly Workload

My first step was to gather information on the work volume by time of day. The Chief gave me a table showing the number of incidents over the past year. I calculated the averages for each one-hour period of the day, which are shown below.

This department is busiest from 12 noon to 7 p.m. and slowest from 3 a.m. to 7 a.m. Given their limited budget, I decided to only show them two different approaches:

• Approach #1: two 12-hour shifts with one 8-hour overlay shift from 11 a.m. to 7 p.m. - which increases coverage on their busy period
• Approach #2: four 10-hour shifts - so the overlaps run from 11 a.m. to 3 a.m. - which reduces coverage on their slow period

Daily Workload

The next step was to see if the workload varied from day to day. Here are the average number of incidents that I calculated from the Chief’s data.

The daily variations were nowhere near as large as the hourly variations, suggesting that steady coverage throughout the week would be okay. In many police departments, Friday and Saturday are often busier and therefore warrant custom-designed work patterns featuring higher coverage on those two days. That was not the case for this client.

Shift Assignments

I allocated the 15 officers to the shifts as follows:

• Approach #1 (8&12-hour shifts):
  • 12-hour day shift = 6
  • 12-hour night shift = 6
  • 8-hour overlay shift = 3
• Approach #2 (10-hour shifts):
  • First 3 shifts = 4 each
  • Last shift = 3

Schedule Details

For each approach, I created 2-3 options showing different work patterns. I’m skipping all the schedule details, like shift start/end times and work patterns, and jumping to resulting coverage, since these are only applicable to this particular situation.

Coverage

Conclusions

By starting the schedule design process with the workload (rather than desired shift lengths or popular schedule patterns), I identified two approaches that would match the coverage with the workload. After allocating the staff to the shifts, I generated a few different work patterns so the organization could evaluate the trade-offs and choose the one that most people preferred.

Had the Chief kept their existing 8-hour work pattern, the coverage would have varied between 3 and 4 people around the clock. Had he found a 10-hour work pattern using just 3 shifts, the coverage would have varied between 2 and 3 people. Would they have been happy with these? Maybe - not knowing that superior options were out there. 

By hiring me, they not only discovered different approaches, but also were given alternative patterns for each approach. They were able to show these options to the officers, so they could voice their opinions and secure a more widely acceptable solution. The organization got a more effective schedule and the officers appreciated being involved in the schedule selection process and the opportunity to choose from multiple options.

• Coverage. Many organizations don’t need the same number of people working at all times. Yet the free templates found on the Internet produce constant coverage.
  
  
• Staffing. If your staff size doesn’t match the number of crews in the schedule, this will result in uneven coverage. Although a template looks attractive, it might require more employees than other, more efficient patterns.
  
  
• Pay Week. Each template works best for a certain overtime / pay week, e.g., Sunday to Saturday. Some schedules can be modified, but some can't. This can result unbalanced work week hours and a loss of weekends off for employees.
  

So, if popular work patterns aren't always the best 24/7 shift schedule, what should you do? Here are the steps we follow:

• Start with the workload and coverage requirements. How many people do you need at work on each shift? Does this stay the same all week? This is the starting point for all schedule design efforts. 
   
• Do you have enough staff? Overtime often may need to be built into the schedule to avoid additional hiring. If there is more staff than necessary, we'll show you different ways to utilize them.
  
  
• We then evaluate your schedule preferences to see if they're feasible. If the resources are adequate, we start the actual shift schedule design. We always try to show you multiple approaches as well as multiple patterns for each approach. The goal is to satisfy your specifications and explore possibilities you may not have considered.

Don't be fooled by free schedule templates. Yeah, they're cheap and look appealing, but they're not necessarily going to make the best use of your staff. And they may not give them as many weekends off as other approaches. Please check with us first. You and your employees will be glad you did.

I'm sure this happens all the time. This guy was brave enough to say what all the others were probably thinking: "Why pay, when you can find schedules online for free." They just don't see the value in paying for professional scheduling assistance. They think they can either figure it out themselves or find schedule examples on the internet.

While it's possible to find schedules on the internet, rarely are they matched to the staff size, coverage requirements, scheduling approach, or pay week. That means the schedules won't work properly and the users will have to live with sub-standard results. Worst of all, they'll never realize that they could've had something far better.

So how do I communicate the value of professional scheduling help? I can't compare my recommended schedules with whatever they came up with. If people are willing to live with a schedule that doesn't produce the right coverage or doesn't provide something attractive for the workers, how can I convince them that spending $150 or $300 would have avoided these problems. 

I've been charging the same prices for over 20 years now. And my clients tell me they love what they got. They especially like the fact that they got multiple options and approaches to compare them and weigh the pros and cons. If you want to see the best possible schedule with more than one pattern, and you're willing to pay a small fee, please contact me. Here's a link to a form that has all the questions I'll need answered.

You search for "free schedule templates." You get page after page of websites that sell scheduling software or offer blank forms and formatted spreadsheets. Some feature common work patterns for 8, 10 or 12-hour shifts. The question is: will any of these schedules work for you?

The best work schedules must be designed around specific staff sizes and pay weeks. If you don't have the same parameters as the free template, you could end up with coverage that is inadequate or inconsistent from day-to-day, unnecessary overtime, and fewer weekends off.

Yes, you can make some of these schedule templates to work for you. It could be as simple as changing the days of the week to match your pay week. In some cases, you might have to tweak the work pattern to make it work properly. And sometimes, nothing will help. For example, how do you use a pattern intended for 4 crews when you have 11 employees or how do you use a 12-hour shift schedule when your coverage varies in 8-hour increments or you need different coverage on the weekends? 

Wouldn't it be better to find schedules matched to your unique circumstances? We think so. That's why we custom-design schedules around your requirements and preferences. We also show you alternative approaches/options so you can compare them and let your employees debate the pros and cons of each one.

Don't pick a template just because some other company is using it or a few employees recommended it. It might be free, but it could cost you a bundle (though you'd never realize it). Get started today with schedules designed by an expert. Schedules that are matched to your situation. Schedules that make optimal use of your staff and offer maximum weekends off.

If you ask a group of shiftworkers to describe their ideal shift schedule, you'll probably hear statements like these:

• “Monday through Friday with 8-hour day shifts.”
• “Monday through Thursday with 10-hour day shifts.”
• “Thursdays only -- so I can pick up my check.”
• “I’ll just stay home, and you can mail me the check!”

These statements illustrate how much value shiftworkers place on their time-off. In fact, if compensation is unaffected, time-off is the shift worker’s primary consideration when comparing alternative shift schedules. Having adequate time-off allows them to have a life outside of work, i.e. the ability to balance their lives at work with their lives away from work.

There are four types of time-off that employees consider when evaluating a shift schedule:

• Weekends off
• Total days off
• Daily time off
• Consecutive days off

We will examine the schedule attributes that drive these four different types of time-off, supplementing this discussion with statistics from our surveys of over 20,000 shiftworkers working 24/7 schedules.

Weekends Off

Of the four types of time off, the number of weekends off is the usually the most important. The desire to increase the number of weekends off is a common reason for adopting longer shifts. The graph below shows the maximum number of full weekends off (Saturday and Sunday together) per year that are possible with 8-hour and 12-hour shifts (13 versus 26 weekends off).

Of course, the actual number of full weekends off depends on more than just shift length. Other factors include the number of consecutive days worked, the pattern of on-off work days, the amount of overtime, and the day the pay week begins. But, as a general rule, longer shifts will enable workers to get more full weekends off.

A key consideration with weekends off is predictability. Most shift workers (82% in the survey database) are willing to work their fair share of weekends. They simply want sufficient advance notice and no last-minute changes. This allows them to make plans for the weekend and not have to worry about getting an unexpected weekend assignment.

Total Days Off

Many shift workers also favor schedules that offer more total days off overall. As shown in the chart below, 12-hour shifts provide twice as many days off each year (compared to 8-hour shifts) for the same number of hours worked each week (182 days off versus 91 days off). 

The substantial increase in days off is one of the reasons three-quarters of all shift workers prefer to work longer shifts. This is shown in the chart below:

Daily Time-Off

The third type of time-off is the number of hours off on the days of work. As seen in figure above, a quarter of the shift workers prefer shorter work days even though they would have to work more days a week. Shiftworkers who are older, have childcare concerns, are going to school, have second jobs, or participate in other non-work activities on workdays often prefer 8-hour or 8&12-hour shift schedules so they can have more “free” time each day.

Consecutive Days Off

The fourth type of time-off is the number of consecutive days off in the schedule. In the figure below, you can see that most shift workers prefer to work several days and then take a long break, i.e. get more consecutive days off. In general, there are two ways to get more consecutive days off. One way is to work 12-hour shifts. The other is to work longer stretches of days in a row.

With 8-hour shifts, a schedule that is based on working 7 shifts in-a-row can offer up to one 4-day break every month. With 12-hour shifts, a schedule that is based on working 3 and 4 shifts in-a-row can offer up to a 7 or 8-day break every month.

Discussion

It is clear that shift workers place a high value on their time-off. This is what enables them to reach a balance between work and their personal lives. What is not clear, however, is which type of time-off the schedule should emphasize. Should the schedule have 12-hour shifts to provide more weekends off and more total days off? Should the schedule mix 8-hour and 12-hour shifts to satisfy both those who want more weekends off and those who want more time off each day of work? Should it have longer stretches of days worked in a row to provide more consecutive days off?

While recognizing that each work site will have its own unique set of preferences, our surveys offer some additional insight into this dilemma. With each of our clients, we show the workers several different schedule options that satisfy the client’s business coverage requirements. By educating employees about the various possibilities, we enable them to make more informed choices from the schedule alternatives.

The options we show employees typically include one or more 8-hour, 10-hour (infrequently because they are not a good match with most 24/7 operations), 8&12-hour, and 12-hour schedules. Although the schedules for each shift length may differ from site to site, the results indicate a much stronger preference for schedules that incorporate 12-hour shifts.

Summary

When managers face the possibility of changing shift schedules, it is beneficial to be familiar with the schedule features that offer employees the best opportunities for work/life balance. This doesn’t replace the need to survey the workforce to determine their unique schedule preferences, but it does provide insights that will be valuable during the change process.

Although 75% of the shift workers would rather work longer shifts in order to get more days off, this does not always mean that 12-hour shifts are best. Some workers place a greater value on the hours off each day instead of the number of days off each week. Other schedule features such as the number of consecutive days of work are equally important in helping some individuals realize the type of time-off they prefer. Despite these qualifications, 12-hour shifts are clearly a favorite, gaining the highest ratings at nearly every organization we’ve worked with.

We showed employees examples of 24/7 schedules using different shift lengths and asked them to rate the different shift lengths. Here are the results:

Ratings definitions:

     5 = I like it a lot

     4 = It has potential to be good

     3 = Neutral or not sure

     2 = It doesn't look promising

     1 = I don't like it

Are you surprised? If you simply asked your employees whether they wanted 8-hour or 12-hour shifts, you'd probably hear 80% saying they'd prefer 8-hour shifts. But if they saw the actual schedules, 12-hour schedules would likely come out on top. So please don't fall into this trap of thinking your group doesn't want 12-hour shifts. You have to show them actual schedule examples so they can make a truly informed decision.

The same goes for 10-hour shifts. Not only are the 10-hour schedules less attractive than the 12s, but you run into a bunch of problems. I've written many, many articles about this. Please do a search on this website for 10-hour shifts if you want to read a few of them.

In addition to more days off, employees also tend to prefer longer breaks between work days. Here are more results from our surveys of shiftworkers in 24/7 operations:

The demand for schedules that will improve work like balance makes it critical that you show your employees examples of both 12-hour and 8-hour schedules with more consecutive work days. This way, they can see and better judge whether the increased time off is worth the longer shifts OR the need to work more days in a row. Let us show you a few examples of each to make it easy for you to accomplish this. Get started here:

We found that asking specific shift lengths did not give reliable answers since it was based on perceptions rather than actual schedules. When we showed the shiftworkers actual schedule examples using different shift lengths, here is how they responded:

Ratings definitions:

     5 = I like it a lot

     4 = It has potential to be good

     3 = neutral or not sure

     2 = It doesn't look promising

     1 = I don't like it

1. Coverage. The primary purpose of the schedule is to match the coverage with the workload, so this should always be your first step. If you start by searching for schedules with a desired shift length or a popular work pattern, you won't get an effective schedule. Your schedule needs to be designed around the number of people you need working during different times of the day on each day of the week that you're open. You can read more here:  Variable Workloads

2. Shift length. How many hours a day are you trying to cover? If it's less than 12 hours, you should use that as the shift length. If it's more than 12 hours, you'll need two or more shifts. Shifts less than 8 hours long will require part-time employees. If you are covering 24 hours a day, you might be able to use 8, 10 or 12-hour shifts. This guide will help:  Shift Length Selection

3. Format. If you have more than one shift per day, you'll have to decide if you want employees to always work the same hours (i.e. the same shift), or if you want them to work different hours from time-to-time, i.e. rotating shifts. Most full-time employees will prefer to work the same hours (i.e. fixed shifts). On the other hand, you may want them to gain experience both opening and closing, or working during both the busy and slower periods. Read about the pros and cons of each approach here:  Fixed vs. Rotating Shifts.htm

4. Staffing. Determine how many people it takes to produce the desired coverage. Do you need to hire more staff or increase the overtime? Here's a tool to help:  Staffing Calculator

5. Work Pattern. Develop alternative work patterns. Most shift lengths have a number of popular patterns for 24/7 coverage. Will any of those work? You may need to modify them or create new ones from scratch. It's critical to match the schedule to the organization's pay week to avoid unnecessary overtime and to ensure maximum weekends off for employees.

6. Alternatives. When I design schedules, I often look for alternative approaches using different shift lengths or combinations of shift lengths. For example, in 24/7 operations with an uneven workload, you might be able to use 8-hour shifts, combined 8 and 12-hour shifts, or sometimes even 10-hour shifts. For each approach, I then try to come up with a few different work patterns. Every option has different pros and cons, so having alternatives to compare will help you find the best schedule.

For example, suppose you need 2-person coverage on every shift. With 8-hour fixed shifts, this would require 9 employees (3 per shift). With 10-hour fixed shifts, it would take 12 employees (4 on each shift). This is a 33% increase in the staffing, making it unaffordable for most organizations.

This is not the case for all situations, however. Let's say you needed 2 people on the day and afternoon shifts and only 1 person on the night shift. WIth 8-hour fixed shifts, this would require 8 employees. With three 10-hour fixed shifts, this would require 10 employees. But if you used FOUR 10-hour shifts, it would only require 8 employees. Here's one way to match that.

Assign 2 people to each of the following four 10-hour shifts.

This would produce 2-person coverage from 6 am to 10 pm and 1-person coverage from 10 pm to 6 am. With 2 people on each shift, there would be one day every week in which both people are scheduled to work (since everyone is working 4 shifts or 40 hours per week). This would give you 4-person coverage from 6a to 10p and 2-person coverage from 10p to 6a on that one day every week. You could use this extra coverage for group meetings, training or other purposes.

This approach only works if the coverage for 16 hours a day is double the coverage for the remaining 8 hours. So it would work if you needed 2-person/1-person, 4-person/2-person, 6-person/3-person, 8-person/4-person and so on.

If you want to get really complicated, you could boost the coverage on one shift. This would give you extra coverage for that 10-hour period. For instance, you could assign 4 people to the afternoon shift. This would give you 2-person coverage from 6a to 12p, 3-person coverage from 12p to 10p, and 1-person coverage from 10p to 6a.

Obviously, this can get really complicated. If you are dead-set on adopting 10-hour shifts, why not contact us for help. Get started by filling out this form:

WIth fixed shifts, you can adopt a schedule that has fixed days of work or rotating days of work. A fixed-fixed schedule means you work the same days every week on the same shift. A fixed-rotating schedule means you always work the same shift, but the days change from week-to-week, usually following a set pattern.

Employees like the predictability of a fixed-fixed schedule. It's easy to plan the rest of your life around it. Surveys of shiftworkers found that predictability is the most important schedule feature, higher than weekends off, coverage for vacations, ability to get overtime, maximum time off, and others. You can read more about this here:  Schedule Predictability.

Fixed day schedules are frequently used in police departments and companies that operate less than 24/7, especially those that have a lot of part-time employees. With police, the officers bid on both the shift and the set of days worked. This is usually done once a year. They do this to reward seniority, since the most senior officers get the "best" schedules.

I've run into a number of medical facilities that create a new schedule every week. The most senior people have a fixed set of days they work. The scheduler then contacts everyone else to fill in the gaps. This is the absolute worst way to schedule. Not only is it a lot of work for the scheduler, but the junior employees never know when they will be working until just before the week begins.

With companies using part-time employees, fixed days makes it easier to find and schedule the part-time workers. They can work around their school schedules or other part-time jobs. They are often forced to build the entire schedule around the availability of a few key, part-time people.

The biggest problem with schedules using fixed days of work is that the employees are not treated the equally. Some people get both the shift they prefer AND every weekend off. Others (usually the newest, least-senior folks) get the worst shift and have to work every weekend. Double ouch! You can read more about this here:  Fairness.

Most of the schedules I design feature rotating days of work. The schedule follows a multi-week pattern. If you look at the 24/7 schedules examples that I sell (Schedule Examples), you'll find various options with 8 or 12-hour shifts that follow a pattern that lasts anywhere from 2 weeks to 20 weeks. When I custom design schedules, I usually match the length of the pattern to the number of employees on a shift. For example, if there are 5 people on a shift, I would create a 5-week pattern.

With rotating days of work, every employee on a shift is treated exactly the same. For example, with 5 people on an 8-hour shift, all 5 will get the same number of weekends off (maybe 1 or 2 weekends off every 5 weeks). They are all working the same pattern. It's just that they are in different weeks of that 5-week pattern. You are still rewarding seniority by allowing the most senior employees to bid on the shift they prefer. To me, this is best for everyone.

Most of the issues I raise are management concerns, like the fact that 10-hour shifts require at least 25% more staff than 8 or 12-hour shifts. Nevertheless, employees tend to believe that 10-hour shifts are the ideal shift length. They would do anything (maybe including a pay cut) to get them. Since employees love them so much, maybe it's worth the extra cost. After all, wouldn't it be great to have a happy, enthusiastic workforce? 

The table below shows the staff needed to different levels of coverage:

Coverage levels greater than 5 would either be a multiple of one of the levels shown or it would require a custom-designed schedule. For example, 6-person coverage would use a schedule for 3-person coverage, whereas 7-person coverage would require a custom-designed schedule.

With some of these coverage levels, the schedule would have one or two overlapping days. This will produce more coverage than needed. This is necessary to ensure 40-hour work weeks. You can only avoid this by having an occasional 30-hour work week, which few employees would tolerate.

3-person coverage is the only level that would require some overtime in the schedule (a 50-hour work week once every 5 weeks). If you want to avoid the OT, you'd have to employ 6 people per shift or 18 total employees. I don't think it's worth it, but that's your call.

• Picking 10-hour or 12-hour shifts when the workload varies in 8-hour increments.
• Using a schedule with constant coverage when their workload varies from shift-to-shift.
• Selecting a schedule pattern (e.g., 4-on-2-off) that requires 6 people per shift, when they have something else.
• Picking a schedule that requires 18 people when other options only require 16.
• Adopting a schedule that is great for day shift, but terrible for night shift.

I'm sure there are plenty of other possibilities, but you get the idea. Many people forget that the primary purpose of the schedule is to match the coverage with the workload. To achieve that goal, you need to start with the number of people needed at different times of the day throughout the week. In many cases, this will limit which shift lengths are feasible. You can read more about that here (Shift Length Selection (shift-schedule-design.com). 

Once you have the shift length(s) established, you need to find or create a pattern that will produce the desired coverage with minimal resources and with maximum weekends off. There is no way that an internet search will ever help with that. 

What do most people do? They find a schedule or create one that they think looks good, adopt it, and live with a mediocre solution, never aware that other approaches or work patterns would have been far superior. They avoid hiring a scheduling expert to save a few hundred dollars and end up costing the organization more than that every week because they got a solution for free. 

Wouldn't it be better to have someone with scheduing expertise go over your situation, show you alternative approaches (e.g., 8-hour fixed shifts vs. combined 8 and 12-hour fixed shifts), and lay out a few different work patterns for each approach? Since the options would all be in the same format, they would be easy to compare and evaluate. You could show them to your workers and let them debate the pros and cons of each option. This is way scheduling should be done.

Unfortunately, this can be in direct conflict with the common employer goal of maximizing employee utilization. For work schedules, this means achieving maximum coverage for the lowest possible cost. In 24/7 operations, “lowest cost” often requires keeping the headcount as low as possible and adopting a schedule that averages 42 hours a week (Why Eliminating Overtime in 24/7 Schedules Can Be Costly).

Thus, when it comes to choosing the best work schedule, management and the workers have different goals. Employees focus on the time off. Managers focus on minimizing headcount and cost. So, how do you strike a balance between these opposing points of view?

If you start from the employee perspective, you could end up with something that the employer just can’t afford. A good example is a company that works 24/7 and has a relatively steady workload. The employees want to change from 8-hour shifts to 10-hour shifts. This would require the company to hire 25% more staff (10 hour shifts). For most companies, this is clearly infeasible.

But, if you ignore what the employees want, you risk having high turnover, increased absences, and reduced productivity. As Mike Michalko recently commented on my website, “Too little emphasis on the employee leads to turnover and the high costs associated with onboarding and training. This is aggravated with needed positions in a highly competitive job market. If an employer doesn't address employee satisfaction, they'll end up training someone else's workforce.”

So, where do you start? I think it’s important to reflect on the reason you have a schedule in the first place. Most people think of the schedule as an on-off work pattern for a specific shift length, for example, a 5-on-3-off pattern for 8-hour shifts or a 2-3-2 pattern for 12-hour shifts. While it's true that the shift length and work pattern are essential components of the schedule, they don’t explain why the schedule is needed. 

 
The real purpose of the schedule is to ensure proper coverage:  the right number of people with the right skills at the right time and place. If the coverage isn’t adequate or matched to regular variations in the workload, the group won’t be able to provide the amount or quality of product/service expected by its customers. The schedule ensures that the organization effectively fulfills its purpose of satisfying the needs of its customers.

Therefore, the top priority for the schedule must be to maintain a level of coverage that matches customer demand. In most cases, more than one approach (usually different shift lengths) is possible. I’ve previously discussed how the hours of operation and the workload variability dictate the best choice of shift length(s):  (Shift Length Selection).

As an example, consider a company that operates 24/7 and needs 2 people working at all times. They first have to decide whether to use fixed shifts and rotating shifts. As a general rule, employees prefer fixed shifts whereas employers prefer rotating shifts (Fixed shifts vs. rotating shifts). In this example, we’ll assume they choose fixed shifts. Next, they have a choice between 8-hour shifts or 12-hour shifts. The 8-hour fixed shifts will require 9 employees working an average of 37.3 hours a week, whereas the 12-hour fixed shifts will require 8 employees averaging 42 hours a week. They decide to narrow the search to these two approaches.

For each approach, several different work patterns are possible. These patterns will vary in terms of the number of consecutive days of work and the nature of the days off. In general, the longer the blocks of work days, the longer the blocks of days off and the longer the weekends off.

Once the alternative patterns are developed, the company should involve the employees who will be working the schedule (Strategic Schedulers Enjoy Remarkable Success). The workers must choose between longer days of work more time off. They also must choose between longer blocks of work days and longer blocks of days off. The majority will decide how important work-life balance is and what sacrifices they are willing to make to achieve it.

To summarize, these are the recommended steps in changing employee work schedules:

1.       Establish the organization’s coverage requirements by time of day and by day of the week. Do you need the same number of people all day long? Maybe there is less work during the nighttime. Do you need the same number of people throughout the week? Maybe there is less work during the weekends. Here’s an example for a company that works 24/7:

2.       Identify different approaches (usually two different shift lengths) that will efficiently achieve the organization’s coverage requirements. The hours of operation and regular workload variations will play a key role in this step. Approaches that are highly inefficient will not be considered, e.g., unnecessary double coverage or excessive staffing requirements.

3.       Find alternative work patterns for each approach. Alternatives will vary the number of consecutive days of work, which will affect the amount and the nature of the time off.

4.       Involve employees in the review of all the options and final selection of the schedule. This gives them the opportunity to decide whether the improved time off is worth the (a) longer days of work, (b) more consecutive days of work, and/or (c) the average weekly hours of work.

Although work-life balance is not the starting point when changing work schedules, it is addressed by identifying different approaches/patterns that satisfy the coverage requirements, and then allowing employees to review, discuss, and vote on their preferred option.

The problem is that few companies have enough resources to make the change to 10-hour shifts. If you are simply replacing your three 8-hour shifts with three 10-hour shifts, your coverage will be reduced by 25%. For example, if your current 8-hour schedule produces 4-person coverage, a new 10-hour schedule would reduce that to 3-person coverage. 

Why is that? Let’s look at a simple example with rotating shift schedules. Here’s a popular 8-hour pattern called the Continental.

8-Hour Shifts

Key:

D8 = 8-hour day shift

A8 = 8-hour afternoon shift

N8 = 8-hour night shift

This is a 4-week, rotating schedule operated by 4 crews. When the schedule first starts, the crews are assigned to specific weeks in the cycle. Crew A is assigned to start in Week 1, Crew B is assigned to start in Week 2, and so on. At the end of each week, the crews rotate down to the next week in the cycle. Crew A moves to Week 2, Crew B moves to Week 3, etc. When a crew completes the 4th week, they rotate up to Week 1. 

Yes, this is a terrible schedule to work. You work 7 shifts in a row and you have to change shifts every 2-3 days. Worst of all, you only get one weekend off every 4 weeks. 

You'll notice that there is a D8, A8, and N8 under each of the days of the week. This means one crew is scheduled to work each shift, all week long. Maybe not the same crew, but there will always be one crew scheduled for each shift. If the total staff is 16 people, each crew would have 4 employees. That means there would be 4 people at work at all times on a 24/7 basis.

Now let's see what happens if you change to a 10-hour rotating shift schedule.

10-hour Shifts

Changing to 10-hour shifts requires creating a 5^th crew and it doesn’t get rid of the overtime in the schedule. There are better patterns than this one that would give you 2 weekends off every 5 weeks. I can show you options that do this, but not for free.

Since the staff size (16) hasn't changed, four of the crews will only have 3 people and one will have 4 people. This means the coverage will now be only 3 instead of the 4 you had with the 8-hour shifts.

The positives of the 10-hour schedule for employees are that you get more days off (3 days a week for 4 out of 5 weeks) and more weekends off (up to 2 weekends off every 5 weeks). Negatives are the smaller breaks and the change in absence coverage.

With 10-hour shifts, you can't hold people over to cover an absence like you did with 8s. Absences have to be covered by calling people into work who are scheduled to be off. As an employee, you could end up working 5 or more shifts a week depending on the absence rate and whether you had any extra capacity before making this change.

The key question of course is whether it’s worth switching to 10-hour shifts. Increasing the average hours of work by 25% or hiring 25% more employees is hard to justify. Reducing the coverage by 25% is not a good choice either. Would the employees benefit that much? Maybe, maybe not. I find it pretty hard to justify.  

Don’t get me wrong. I’ve written plenty of articles about how to use the 6 hours a day that 10-hour shifts overlap to match the coverage to a variable workload. 10-hour shifts do have a place, if you can afford it. It’s been my experience that few smaller organizations (less than 50 employees) can do it.

Here is another article about 10-hour shifts with links to several of the other articles I've written on this topic: 10-hour Shifts.

24/7 Operations

If the coverage requirements are steady throughout the day, then the best choice is either 8-hour or 12-hour shifts. That's because these shift lengths don't overlap during the 24-hour day. Other shift lengths (9, 10, or 11 hours) would overlap. This not only doubles the coverage during the overlap(s), but it also increases the staffing requirements. Three 9-hour shifts require 12.5% more staff, three 10-hour shifts require 25% more staff, and three 11-hour shifts require 37.5% more staff.

If the coverage requirements vary fairly regularly by time of day, the organization can either use:

• Fixed shifts with different staffing levels on each shift that match the coverage requirements, e.g., 4 people on day shift, 3 people on evening shift, and 2 people on night shift.
   
• Overlapping shifts, e.g., 9 or 10-hour shifts. By changing the shift start and end times, the daily overlaps can be consolidated and matched to the busy period.
   
• An overlay shift that boosts the coverage for the length of that additional shift, e.g., a 6-hour shift from 3 p.m. to 9 p.m.

Less than 24/7 Operations

If the coverage requirements are steady, the best choice would be a shift length that matches the hours of operation - up to a maximum of 12 hours. For example, if the company is open for 11 hours a day, the most efficient choice would be an 11-hour shift, since this would require the smallest number of employees and would avoid any overlapping shifts. If the daily hours exceed 12 hours, then 2 shifts are needed each day. For example, a company that is open 14 hours a day could have two 7-hour shifts or one 8-hour shift and one 6-hour shift.

If the coverage requirements vary by time of day, the organization can either use:

• Fixed shifts with different staffing levels on each shift that match the coverage requirements, e.g., 2 people on the first shift and 4 people on the second shift.
   
• Overlapping shifts. For example, if the late afternoon is busiest, a company could use a 12-hour day shift and an 8-hour evening shift that overlaps from 4 p.m. to 8 p.m.
   
• An overlay shift that boosts the coverage for the length of that additional shift, e.g., a 4-hour shift from 3 p.m. to 7 p.m.

Summary

If you want to maximize employee utilization, your shift length should be based on the whether the workload and associated coverage requirements remain steady throughout the day or vary on a fairly regular basis. Steady workloads should have shifts that don't overlap for more than the length of a meal break. Variable workloads can be addressed in several different ways.

Many people choose the shift length for other reasons. For example, they choose 10-hour shifts, hoping to get an extra day off each week, or they choose 12-hour shifts, hoping to get more weekends off. They don't realize that this may increase the headcount requirements, not match the coverage with the workload, or utilize the staff ineffectively.

• You won't have to spend so much time creating new schedules.
• You won't have to struggle with being short-handed because you couldn't fill a time slot (i.e. a shift).
• Employees will appreciate knowing far in advance when they have to work and, more importantly, when they will be off.
• Employees like getting occasional weekends off (as opposed to having to work every Saturday, for example).

Unlike 24/7 schedules, free examples of schedules for your type of business are hard to find because there are too many possibilities: 

• Different hours of operation.
• Different coverage requirements.
• Different number of employees.
• Different mix of full-time and part-time employees.
• Different pay weeks.

What do schedules for less than 24/7 coverage look like? Well, that depends on all of the above variables. Here are 2 simple examples:

Example #1. Open 10 hours a day all week. Need at least 2-person coverage at all times. Busiest day is Monday. 4 full-time staff. Pay week begins on Thursday.

Each crew (A and B) has 2 employees working a 10-hour day shift (D10). Crew A begins the schedule in Week 1; Crew B begins in Week 2. After finishing the initial week, they rotate to the next week of the schedule. Crew A rotates to Week 2, while Crew B rotates to Week 1. They continue this 2-week pattern indefinitely. Note that Monday is the only day of the week with two D10s underneath it. That means both crews are scheduled to work on this busiest day of the week. Note that the schedule begins on Thu. Had we started with a different day, the 2-day break in Week 2 might not have fallen on the weekend (Sat & Sun).

Example #2. Open 14 hours a day (7 a.m. to 9 p.m.) on Mon-Sat. Need at least 1-person coverage at all times. Need 2-person coverage from 4 p.m. to 7 p.m. 2 full-time staff and 2 part-time staff. Pay week begins on Saturday.
 

The two full-time employees (A & B) work a 2-week schedule on a 12-hour day shift (D12) that runs from 7 a.m. to 7 p.m. Employee A begins in Week 1, while Employee B begins in Week 2 of the schedule. After finishing the initial week, they rotate the the next week. Employee A rotates to Week 2 and Employee B rotates to Week 1. The two part-time employees (C & D) do not rotate. They work the same 3 days each week. C works a 5-hour afternoon shift (a5) from 4 p.m. to 9 p.m. on Thu, Fri, and Sat. D works the same shift Mon, Tue, and Wed. The 5-hour shift overlaps the 12-hour shift from 4 p.m. to 7 p.m. giving the company the 2-person coverage they are looking for.
 

We could keep going, but unless you happen to have the same combination of hours, coverage requirements, staff size/composition, and pay week, additional examples aren't going to be much help. So what's the best approach for creating a schedule? You can contact us for help (Request Quote) or you can follow the steps that we do (Employee Work Schedules).

Workload Distribution. If the workload is steady at all times, 8-hour or 12-hour shifts would be the best choice. If the workload varies by time-of-day, you will either need to allocate more staff to certain shifts or adopt a schedule with overlapping shifts (e.g., 10-hour shifts or combined 8 and 12-hour shifts). If the workload varies by day-of-the-week (or weekdays vs. weekends), you will need a custom-designed work pattern.

Employee Preferences. If you ask employees for their preferences, roughly 80% will say 8-hour shifts. However, if you show them examples of 8 and 12-hour schedules, 80% will prefer the 12-hour schedules. That's why it's important for them to see actual examples rather than just voicing an opinion on what they want.

There is more than just shift length to consider, of course. Should you have fixed shifts or rotating shifts (https://www.shift-schedule-design.com/Fixed_Shifts)? What are the best shift start/end times (https://www.shift-schedule-design.com/Blog?m8:post=fatigue-in-the-workplace-early-day-shift-start-times)?

I'm going to describe what I did to address these problems because I think they are common to many hotels, motels, and bed & breakfast establishments.
 

I started by asking my client how long it took the employees to do their jobs. She said the housekeepers only needed 8 hours a day, while the maintenance crew was active for 16 hours day. Both jobs were needed 7 days a week. Then I asked her how many people she needed at work each day.
 

The housekeepers needed 9-person coverage on an 8/7 basis (8 hours/day for 7 days/week). I told her that this would require at least 12 employees. They could be organized into 4 crews of 3 people each. This was quite a few less than the 16 people they currently employed. However, because this group had a high absence rate, my client decided to increase the crew size to 4 people. This was probably more extra coverage than necessary, but it avoided layoffs. This would completely eliminate the need for overtime to cover absences. They would work a 4-week schedule in which three weeks were 40 hours and one week was 48 hours. This would average 42 hours a week over the 4-week period.

The maintenance crew needed 1-person coverage in the mornings and evenings. They needed 2-person coverage in the afternoons. This would require three 8-hour shifts. Because they worked fixed shifts, this would take six employees (2 per shift). I laid out a 2-week pattern for my client. In order to give everyone 40 hours of work each week, there would be 3 days a week in which both employees on each shift were scheduled to work.

I suggested that she consider two 10-hour shifts instead of three 8-hour shifts. The shifts would overlap for 4 hours giving them the desired 2-person coverage for part of the afternoon. This would only require 4 employees and there would only be one day a week in which all 4 employees had to work. She decided that the absence rate was low enough in this group that it wouldn't be necessary to build in extra coverage like she did with the housekeepers. Due to various problems with some of the maintenance staff, layoffs were not a concern for her.
 

Do you have a similar situation in your hotel or B&B? Can't figure out the best staff size? Have trouble maintaining the right coverage? Are you experiencing high overtime levels or absences that can't be covered? Instead of having a manager create a new schedule every week, you need a set schedule that produces the desired coverage with minimal staffing/overtime costs. Please contact us today for help. Here's a link to request a quote for our services.

Ask employees, and some will tell you, "10-hour shifts from Mon-Thu." Others may say, "12-hour fixed shifts with every other weekend off." The common themes are the preferred shift length and format (fixed shifts vs. rotating shifts).

Ask managers, and some will say, "We need more coverage on the 2nd shift because that's the busiest part of the day." Others will say, "We need to hire more staff, but upper management has a lid on hiring" or "Overtime is killing us, so we need a schedule that will reduce it." The common themes with this group are coverage and costs.

Unfortunately, the best solutions for employees probably will not produce the best results for managers. For example, 10-hour shifts in 24/7 operations require at least 25% more staff than 8 or 12-hour shifts. And fixed shifts can increase the staffing requirements even further. Ouch! Some of the scheduling preferences just aren't feasible, and some may compromise the organization's mission.

Most organizations simply can't afford to adopt the types of schedules that employees wish they had. So the question becomes, will the best solutions for managers produce good results for employees? I believe they can. Employees won't get their fantasy schedule, but they will get an attractive pattern with good breaks and maximum possible weekends off.

Here is how I define the "best" shift schedules. They should address three goals: (1) optimize coverage, (2) minimize costs, and (3) maximize employee satisfaction. These goals are in priority order. In other words, when designing a schedule, you should start with the coverage allocation, then work on keeping costs down, and finally on what makes employees happy. Reversing this order can wreak havoc on the organization. Here's another article that explains this in much greater detail:  https://www.shift-schedule-design.com/Shift_Schedule_Design_for_Dummies.

For managers of 24/7 operations, 10-hour shifts have a number of shortcomings. The biggest, of course, is the fact that they require at least 25% more staff than 8 or 12-hour shift schedules. That's because you really are covering 30/7 instead of 24/7. There are several other issues, which you can see by reading the articles. 

On the other hand, there are situations where 10-hour shifts are a good choice. If you have a busy period around the same time every day, you can take advantage of the double coverage achieved with the overlapping shifts. You can boost the coverage for 6, 12 or 16 hours a day. This may require odd shift start/end times or adding a 4th shift.

For employees in 24/7 operations, 10-hour shifts are attractive primarily for two reasons:

1. Working 2 extra hours each day in order to get one more day off each week is a reasonable trade-off. Getting that extra day off each week is worth the sacrifice. And 10-hours is seen as a lot more tolerable than 12 hours.
    
2. Most people think that a 10-hour shift schedule will feature 3 consecutive days off, ideally on Friday, Saturday, and Sunday. Who doesn't want a 3-day weekend off all the time?

Unfortunately, in 24/7 operations, these two results aren't always realized. Similar to 8-hour and 12-hour shift schedules that average 42 hours a week, many 10-hour schedules also have overtime built into them. This means that the employees won't always get 3 days off. The number of weeks with only 2 days off depends on the 10-hr schedule adopted. Usually it's once every 5 weeks. 

10-hour schedules in smaller organizations (fewer than 21 people) won't have 3 consecutive days off either. Most of the breaks will be only one or two days long. This can be avoided by adopting a schedule with fixed days of work. The downside of this approach is that few employees will get a full weekend off, let alone a 3-day weekend. Only a few of the most senior employees will get a 3-day weekend off.

To summarize, 10-hour shift schedules for 24/7 operations rarely meet employee expectations for several reasons:

1. Most of these 10-hour schedules don't consistently offer 3 days off every week.
2. They rarely offer 3 consecutive days off. 
3. Typical 10-hr schedules feature a maximum of one 3-day weekend off every 5 weeks or 2 every 7 weeks.

Naturally, all of this depends on the staff size, the coverage requirements, and when the overtime/pay week begins. If you want to know how 10-hour shifts might work for your group, please click the following link, fill out the form, and I'll let you know what's feasible for you:  https://www.shift-schedule-design.com/21.html

I started by telling them that fixed shifts often require a few more employees than rotating shifts. This is true with both 8-hour and 10-hour shifts. This can be critical when the group is already staffed at a minimum or understaffed. They could still use fixed shifts, but they would either have to hire more staff or adopt a schedule with a lot of overtime in it.
 

Next, I went into the problems with 10-hour shifts. I know, everybody loves 10s. But 10s are really inefficient when you're trying to cover a 24-hour day. You need three shifts, which means you're really working 30 hours a day instead of 24 hours. This 25% increase in hours per day requires a 25% increase in staff or a 25% reduction in the amount of coverage. Few organizations can handle this.

That leaves 8-hour shifts and 12-hour shifts. And if the coverage is not the same at all times, a 12-hour shift schedule may not be a good fit. What is needed is a combination of 8s and 12s, for example 8 people on the 12s and 4 people on the 8s. Although the 12-hour shifts might improve the efficiency (i.e. require fewer people), the 8-hour fixed shifts are highly inefficient for low levels of coverage like one person. For example, 1-person coverage requires 2 people and there would be 3 days a week in which both of them are scheduled to work.

I believe that the people who contacted me with no schedule preferences did so to find a scheduling solution to their current situation. What they didn't realize was that they had a staffing problem, not a scheduling problem.

Yes, they might find some schedule changes that are a little more efficient, but not to the extent they hoped to find. And some of those changes might result in schedules that are not very employee-friendly (e.g., 8-hour rotating shifts).

10-hour shifts are a popular choice among employees. However, when used with companies working 24/7, the 10-hour shifts create a few problems. The biggest is that it takes three 10-hour shifts to cover the day. This means the company is actually running for 30 hours a day instead of 24, which will boost the staffing requirements by at least 25%.
 

And, if that's not bad enough, how do you handle the fact that the shifts overlap one another for 6 hours a day? Do you overlap each shift by 2 hours or do you consolidate the overlap so there are 6 consecutive hours of double coverage?
 

If you overlap each shift for 2 hours, do you have one shift sit idle, while the other works? That seems pretty wasteful. The exception would be police departments where the first shift can go back to the office to do paperwork, while the second shift is out on patrol.
 

If you consolidate the overlaps, you might be able to take advantage of the double coverage. Maybe there is a special project that can be tackled, areas that can be cleaned / repaired, or a new production line that can be operated. Companies with variable work volumes can align the 6 hours of overlap with the busy period to match the coverage with the workload. The downside, of course, is that this may result in some weird shift start and end times that won't appeal to employees.

If you are considering 10-hour shifts in your 24/7 business, I hope you'll read the other articles I've written about the limitations of 10-hour shifts. Here are links to the most popular articles:

I have never attempted to understand this state's complex requirements and exceptions. I always advise prospective clients to have their legal representative research this before having me design schedules with anything other than 8-hour shifts.

Recently, I was contacted by Cindy Opeka of O'Peka HR Consulting who stated that she might be able to help. I don't have first-hand experience with her expertise, but thought I would share her comments with you. Here's what she said:

"I'm currently working with a client who is dealing with the Department of Labor. They are up against thousands of dollars in fines. If you work with CA customers, I'd be happy to share info at no charge. I just want to help small employers avoid penalties."

When people search for a new shift schedule, they often cite one of these two goals: (1) better work-life balance, or (2) better staff utilization.

Work-life balance is an employee-oriented goal associated with more or better time-off. And that usually means 10 or 12-hour shifts and/or work patterns that feature fewer consecutive days of work or longer stretches of consecutive days off, e.g., the Pittman or DuPont schedules.

Staff utilization is a management-oriented goal associated with making the most cost-effective use of the employees. If the workload varies by time of day or by day of the week, that can mean matching the coverage with the workload. If the workload or available resources have changed, that can mean squeezing out more coverage. If the absence rate is high, it means trying to maintain coverage that's more than the minimum necessary, while keeping costs minimized.

When work-life balance is the top priority of the search, the resulting schedule will likely be great for employees but less-than-ideal for the organization. There are three reasons:

1.       Effectiveness. Work patterns that are most popular with employees produce constant coverage on a 24/7 basis. If the organization's workload isn't constant, the schedule will not be the best match. 

2.       Efficiency. Most of these popular work patterns use four crews. If the staff size is not an exact multiple of 4, the organization will be wasting some of its resources. 

3.       Cost. 10-hour shifts tend to require at least 25% more staff than 12-hour shifts because they add six hours to the work day (three 10-hour shifts = 30 hours/day). Popular work patterns do not consider absences. The organization either uses overtime to cover those absences or it schedules extra coverage to exceed the minimum necessary. A less-costly approach would be to build relief coverage into the schedule.

So does that mean work-life balance should not be considered when searching for a new schedule? Of course not. But it should never be the starting point for the search. The needs of the organization must always come first. Once those are satisfied, then (and only then) can alternatives that offer more or better time-off be considered.

The managers wanted to see what the different options looked like so they could choose the one that appealled to the most people. I explained that this was not the best way to search for a schedule. The starting point should always be the business requirements. You want to make sure there is adequate coverage and that it matches the workload. You also want to use the resources (staff and overtime) efficiently. Schedule attractiveness can only be pursued after the business requirements are satisfied.

If I assume that these groups needed 1-person coverage on a 24/7 basis, this is what they would see with the six different combinations of shift length and format (fixed vs. rotating shifts):

8-hour Rotating Shifts

1-person coverage requires 4 people working an average of 42 hours a week. With a staff of 5 or 6, they would have 1 or 2 "extra" employees. This extra capacity could be used to increase the coverage, reduce the average hours of work, or to build relief coverage into the schedule to cover absences. The biggest downside is that the schedules are miserable for the employees.

8-hour Fixed Shifts

1-person coverage requires 6 people working 40 hours a week (2 people per shift). There would be 3 days a week in which both employees on a shift would be working, so this is something to keep in mind if there isn't enough room for 2 people at the same time. There would be no extra capacity with this type of schedule. Although not as efficient as 8-hour rotating shifts, they are a little better for employees.

10-hour Rotating Shifts

10-hour shifts always require the most personnel because the group is working 30 hours a day (three 10-hour shifts). I only recommend using 10-hour shifts if the group can take advantage of the 6 hours of overlapping shifts that could be matched to the group's busiest time of the day. 1-person coverage requires at least 5 people working an average of 42 hours a week. If there were 6 employees, this would leave 1 extra. This extra person could be used to increase the coverage on one shift or to build relief coverage into the schedule to cover absences. Even though employees get one more day off each week (as compared to 8-hour schedules), the work patterns aren't that attractive, i.e. quick rotations and lots of 1 or 2-day breaks.

10-hour Fixed Shifts

1-person coverage requires at least 6 people working 40 hours a week (2 people per shift). There would be 1 day a week in which both employees on a shift would be working. During the 6 hours of overlapping shifts on the overlapping day, there would be 4 people at work. If this exceeds the physical capacity of the site, this would not be a good choice. As with fixed 8-hour shifts, there would be no extra capacity.

12-hour Fixed or Rotating Shifts

1-person coverage requires only 4 people working an average of 42 hours a week. With a staff of 5 or 6, they would have 1 or 2 "extra" employees (the same as 8-hour rotating shifts). This extra capacity could be used to either increase the coverage, reduce the average hours of work, or to build relief coverage into the schedule to cover absences. Despite the long days of work, most employees prefer these patterns since they offer twice as many days off and up to half the weekends off.

Summary

Rather than looking for examples of every possible combination of shift length and format (fixed vs. rotating shifts), these groups should first decide what is most important to them:

• Increased coverage. Does the group need more than 1-person coverage for part of the day or during certain days of the week? If so, the desired coverage levels should be the starting point of the schedule search since several options (as pointed out above) have no extra capacity to increase the coverage with.
  
  
• Reduced work hours. Some groups avoid overtime like the plague. They will do anything (including hiring one or two extra staff) so they never have to work more than 40 hours a week. Even though I have argued repeatedly that this is not the best financial approach, many organizations still think the schedule should never have overtime in it.
   
• Relief coverage. If increased coverage isn't needed, any extra capacity can be used to create relief coverage, i.e. time in the schedule available to cover absences. This will reduce the need to cover absences with overtime. Relief coverage works best with rotating shifts since it can be used to cover absences on any shift. With fixed shifts, you would need to build relief coverage into each shift's schedule, so it will require more staff.

Once the priorities are clear, this will narrow down the feasible approaches. There are too many possibilities to discuss here, so if you need more help, please let me know.

Resource Changes

Either the staff size or the group's budget is changing. If the group is getting bigger, there may be opportunities to use the extra capacity to reduce the average weekly hours, boost coverage on one or more shifts, or build relief coverage into the schedule to cover some of the absences. If the group is getting smaller, the average weekly hours of work may have to be increased to maintain the minimum coverage requirements.

Sometimes upper management wants to cut costs but not change the headcount. The group will have to do a cost analysis of overtime in the schedule vs. overtime outside the schedule to determine the best approach. You can read about this here:  http://www.shift-schedule-design.com/Overtime_Issues. The group may also be forced to consider other schedule changes that will lower costs as discussed here:  http://www.shift-schedule-design.com/Cost_Reduction.

New Business Requirements

When the demand for an organization's products or services changes (usually by increasing), this may require them to hire more employees or make more effective use of their current employees. In either case, it's a good time to align the coverage with the workload. We start the schedule design process by evaluating work volumes and the associated coverage requirements by time of day and day of the week. We also consider absence coverage if the resources are adequate.

Employee Satisfaction

When employees search for a new schedule, they are primarily looking for ways to increase the days off and weekends off. When managers cite employee satisfaction as a reason for changing schedules, they hope that the change will reduce absenteeism and employee turnover, or improve productivity and morale issues. Once business requirements are satisfied, we will evaluate solutions that maximize days off and weekends off and, if possible, reduce the need for mandatory overtime.

1. Better staff utilization – coverage that is consistent and matched with the workload
2. Reduced labor costs – lower wages and/or overtime
3. Greater employee satisfaction – more days off and/or more weekends off

Unfortunately, doing well with one goal often means compromising the other two.

Here's an example. Suppose the employees want a 10-hour shift schedule to get one more day off each week and possibly more weekends off. This would certainly help the third goal: greater employee satisfaction. But what would it do to the other two goals?

Since the 10-hour shifts would overlap for 6 hours a day, this would exceed the physical capacity of the work area. Employees from one of the overlapping shifts would be sitting around with nothing to do for 6 hours – every day of the week. This is definitely not a good way to use the staff.

What about labor costs? Well, since the 10-hour shifts would require the organization to work 30 hours a day (three 10-hour shifts), the additional hours of coverage would necessitate an increase in the staff size by 25%. This certainly would not save money.

So how do you find a schedule that satisfies all 3 goals? Simple. Instead of starting the search for a new schedule with a focus on Goal #3: Greater Employee Satisfaction, you start with #1: Better Staff Utilization. You then move to the second goal, and finally to the third goal.

Here are the steps we follow when designing a new employee shift schedule:

• Feasibility. We start by comparing your coverage requirements and scheduling preferences with your staff size to determine the feasibility. Sometimes the resources are inadequate, so different approaches may have to be considered.
  
  
• Possibilities. Sometimes, overtime may need to be built into the schedule to avoid gaps in coverage. Occasionally there may be more staff than necessary, so we'll show you different ways to utilize these "extra" resources.
  
  
• Work patterns. In this third step, we start the actual shift schedule design. Often we can apply common scheduling patterns as a starting point, and modify them to fit your unique circumstances.
  
  
• Options. We create several different shift schedule options to show you the range of possibilities, such as the number of consecutive days worked, different shift lengths, relief coverage, alternative patterns, and so on.

This process ensures that the schedules we create are effective with all three goals, not just one of them.

Reasons for expanding the hours of operation include the following:

• Competition. Once a competitor changes its hours of operation, other local companies in that same line of business are pressured to do the same.
• Customers. Longer hours expose a business to more prospects, which can increase sales. It also makes it more convenient for existing customers, which means more repeat business
• Facilities. When the space or equipment is fully utilized, it's cheaper to increase the hours of operation than it is to rent a larger office/shop or to purchase more/larger machinery.

There are three factors that the business owners should consider when creating work schedules for the employees:

• Coverage. What is the most effective way to match the number of people at work with the workload variations?
• Cost. What is the most efficient way to staff and schedule the employees?
• Satisfaction. Which approach will the employees prefer?

I've discussed these criteria previously, but only in the context of continuous 24/7 operations. Here's a link to the original article: http://www.shift-schedule design.com/Shift_Schedule_Design_for_Dummies. In this post, we will take a closer look at each factor from the perspective of businesses that are less than 24/7.

Coverage

Once a company selects its new hours of operation, it should estimate the workload by hour of the day and by day of the week. The best way to do this is to gather historical data using measures such as:

• Number of jobs or appointments
• Number of in-bound phone calls
• Number of customer visits
• Number of out-bound service calls

Since some calls or visits require more time and effort than others, it might be necessary to classify them into 2 or 3 categories. Each category can be weighted differently to adjust for the time required by employees. A table of the weighted data can help in the selection of shift lengths and coverage on each shift. An example is shown below. Note that Category 2 work takes twice as long at Category 1 work so it counts double in the total work volume.

Days                            Time                        Category 1                  Category 2           Total

Mon-Fri                0800 to 1200                       50                                    4                          58

Mon-Fri                1200 to 1600                       70                                    8                          86

Mon-Fri                1600 to 2000                       85                                   10                       105

Sat                       0800 to 1200                       70                                    9                          88

Sat                       1200 to 1400                       81                                    7                          95

Sat                       1400 to 1700                       92                                    5                        102

As you can see, the volume of work is not constant throughout the hours of operation. It varies by time of day and day of the week. Let's take a closer look at each of these two types of workload fluctuations.

Hourly Variations. With this type of fluctuation, the volume of work changes by time of day. For example, the evenings are often busier than the rest of the day in many retail stores. The three typical ways to address these hourly workload variations are:

• Staggered start times
• Part-time employees that work shifts shorter than 8 hours
• Multiple shifts that overlap one another

Since there are so many different situations, I'll try to give a simple example of each approach.

Example #1. An independent auto repair shop is open from 7 a.m. to 6 p.m. It opens early because the owner wants to avoid commuter traffic. Most customers don't drop off their cars until 8 or 9 a.m., so he starts one mechanic at 8 a.m. and another at 9 a.m. The first mechanic leaves at 4:30 p.m. and the second leaves at 5:30 p.m. The owner stays until 6:00 p.m. to accommodate customers picking up their vehicles after work. The staggered work hours not only extend the coverage to 11 hours a day, but they also match the coverage with the workload.

Example #2. A store that sells bicycles is open from 9 a.m. to 7 p.m. They are busiest from 4 p.m. to 7 p.m. To match the coverage with this workload distribution, they have a 10-hour shift staffed by full-time employees plus a 3-hour shift (from 1600 to 1900) staffed by part-time employees (mostly students).

Example #3. A beauty salon is open from 9 a.m. to 9 p.m. Their busiest time of day is in the afternoon from 3 p.m. to 5 p.m. They match this workload distribution by using two 8-hour shifts (0900 to 1700 and 1300 to 2100). The shifts overlap from 1 p.m. to 5 p.m. This overlap is a little longer than necessary, but it allows the company to only use full-time employees who want to work 8-hour shifts.

Daily Variations. With this type of fluctuation, the volume of work changes throughout the week. For example, many businesses that deal with the public are busier on the weekends than they are on weekdays when people are at work. The two typical ways to address daily work variations are:

• Weekend crews
• Custom-designed work patterns

As with the hourly variations, there are too many possibilities to cover them all, so I'll just give one example of each approach.

Example #4. A stationery store is open every day of the week. The workload is fairly light on weekdays and busier on the weekends. The owner works by himself Mon-Fri. He employs several part-time people to work the weekend shifts. It's easier for him to find people to work weekends since this is usually a second job for them. Plus it gives him the weekends off. The downside, of course, is that the manager is unavailable to supervise the part-time employees. He or she is also unavailable when the store is busiest.

Example #5. A pharmacy is open every day of the week. They tracked the volume of prescriptions filled by day of the week. Wed, Thu and Fri have almost 50% more prescriptions than other days of the week. Weekends are the lightest, whereas Mon and Tue are average. The pharmacy employs 3 full-time pharmacists. All 3 pharmacists work the 3 busy days. Only one pharmacist works on Saturday and Sunday. Two pharmacists work on Mon and Tue.

Cost

Small business owners are especially concerned with keeping costs at a minimum. That's why it's important to compare the cost of different staffing/scheduling approaches before picking one. I'll try to illustrate how to do this.

This example is a retail store that is open from 10 a.m. to 6 p.m. Mon – Sun. Using data on the number of customer visits by hour of the day over the past year, the manager established the following coverage requirements:

Mon-Sun             1000 to 1500       2 people per hour

Mon-Sun             1500 to 1800       3 people per hour

Approach #1. This approach emphasizes the use of full-time employees supplemented by part-timers. There are 3 full-time employees that provide 2-person coverage throughout the week using 8-hour shifts. There are 3 part-time employees that are used to boost the coverage from 3 – 6 p.m. The total cost is calculated below:

3 FT employees * 40 hours/week * $12/hour wages * 1.4 cost of benefits = $2,520 per week

PT employees * 21 hours/week (average) * $10/hour wages = $210 per week (note that it doesn't matter how many part-time employees are used; it's only the total hours per week that's important)

The total cost is $2,730 per week.

Approach #2. This approach emphasizes the use of part-time employees with two full-time employees who will supervise the part-timers. The total cost is calculated below:

2 supervisors* 40 hours/week * $15/hour wages * 1.5 cost of benefits = $1,800 (note that the supervisors' time counts toward the coverage requirements)

PT employees * 53 hours/week * $10/hour wages = $530 per week (note that it doesn't matter how many part-time employees are used; it's only the total hours per week that's important)

The total cost is $2,330 per week.

Based on cost alone, Approach #2 (supervisors + part-time workers) is the best. The owner has to balance the cost savings with the time the manager will spend hiring and training the constant turnover of part-time employees. Although using part-time employees often is the least expensive approach, other considerations may override this.

Employee Satisfaction

Although employee satisfaction is important, it should never be the starting point in the search for a new schedule. I can't count the number of times I've been contacted by managers who selected the hours of operation to justify a shift length that he or she thought employees would like better than 8-hour shifts. They often forget that longer shifts will either increase the staffing requirements or reduce the available coverage.

For example, I had a manager of a business that ran 16 hours a day (two fixed 8-hour shifts) for 7 days a week. They needed 2-person coverage. They used 6 employees working an average of 37.33 hours/week. The manager said the employees were unhappy with the schedule, so he was thinking about changing to two 10-hour shifts.

The problem with two fixed 10-hour shifts with 2-person coverage is that it would require 8 employees or the coverage would drop to 1 person for 2 days a week on each shift. The manager forgot that the extra 2 hours a day for the 10-hour shifts would increase the hours of coverage by 25%.

In most cases, shift length is not left up to employees since this is more or less defined by the hours of operation or the hours in which overlapping shifts are needed. So the choice for employees usually boils down to the preferred work pattern. Here are a couple of examples.

Example #6. A hardware store needs 4 sales people on a 10-hour shift every day of the week. This requires 7 employees working 40 hours a week. To reward the most senior employees, the manager lets them bid on the days they work. He creates two schedule options:

• Option #1. This schedule has 4 consecutive days of work followed by 3 consecutive days off. The downside to this schedule is that only 2 of the 7 will get both Sat and Sun off.
• Option #2. This schedule allows 3 of the 7 to get both Sat and Sun off. However, not all of the schedules feature consecutive days of work.

Example #7. An appliance repair center needs 5 people on an 8-hour shift every day of the week. This requires 7 employees working 40 hours a week. The manager creates two schedule options:

• Option #1. This schedule requires employees to work 7 days in a row. The employees get 2 weekends off every 7 weeks. One weekend off is 3 days and the other is 5 days. All the other breaks at 2 days.
• Option #2. This schedule requires employees to work 2 to 4 days in a row. The employees get 2 weekends off every 7 weeks. Both are only 2 days off. The other breaks are only 1 or 2 days.

In both examples, the employees are shown the two schedules. They discuss the options, particularly the pros and cons. They then vote on the option they prefer. This forces them to make tradeoffs. In Example #6, they must choose the increased likelihood of getting a weekend off. In Example #7, they must choose between more consecutive days of work with longer breaks vs. fewer consecutive days of work with shorter breaks.

Overtime

Since four 10-hour shifts add up to 40 hours a week, some people believe 10-hour shifts will eliminate overtime from the work schedule. Unfortunately, this is not always the case as shown below:

A crew can consist of one to hundreds of officers. Unlike many 8 or 12-hour shift schedules that require 4 crews, 10-hour schedules require 5 or more crews. For example, to have 1-person coverage around-the-clock, you need 5 people if you use rotating shifts and 6 people if you use fixed shifts. To have 2-person coverage, you would need 10 people (5 crews of 2 each) with rotating shifts and 12 people (6 crews of 2 each) with fixed shifts.

The most common 10-hour schedules rely on 5 or 15 crews. These schedules average 42 hours a week, the same as most 8-hour and 12-hour schedules that use 4 crews. I occasionally get calls from Police Captains and Lieutenants who have tried to create a schedule on their own, but can't make it work. They didn't realize that the schedule needed an occasional 50-hour work week or that it required more crews. Overtime is unnecessary only when the schedule is comprised of 6 crews or 21 crews (and sometimes with a crewless schedule).

Overlapping Shifts

A schedule that uses three 10-hour shifts will have 6 hours a day in which the shifts overlap one another. There are two common ways to use the overlaps:

• Overlap each shift by two hours. Officers on the out-going shift can do their paperwork while officers on the in-coming shift are out on the street. This ensures continued coverage throughout the day. This approach tends to be preferred by the officers.
  
  
• Align the overlapping shifts with the busiest period of the day. Coverage can be boosted for 6, 12 or 16 hours a day depending on how the shifts are scheduled. I recommend this approach because the primary reason for having a schedule is to allocate the resources to match the workload. The downside is that it often requires unusual shift start/end times. This approach tends to be preferred by management.

Coverage Reduction

The biggest problem with 10-hour shifts is that they require more resources than 8-hour or 12-hour shifts. A 10-hour schedule requires more staff because the officers are working 30 hours a day (three 10-hour shifts). This will either require 25% more personnel or a 25% reduction in the coverage levels. In most cases, headcounts are frozen, so the impact is reduced coverage on each shift.

Even if sufficient staff is available, they are usually needed for other purposes such as absence coverage. Since the absence rates in most police departments are rather high, most Chiefs opt to use any “extra” staff in one of two ways:

• Increase coverage levels above the minimum. For example, a department needs a minimum of 3 officers on each shift. This requires at least 12 officers working an average of 42 hours a week. They use their staff of 16 officers to provide 4-person coverage. This allows for up to one absence on each shift.
  
  
• Build relief coverage into the schedule. This is often more efficient than increasing the coverage on each shift. For example, the same department only has 14 officers, so they adopt a 14-week rotating shift schedule in which 2 of the 14 weeks are devoted to relief coverage. This requires fewer staff and provides more flexible absence coverage.

When the "extra" coverage is lost, absences (like vacations, sick time, training, court time, etc.) will have to be covered using overtime. This is the most common reason for rejecting the switch to 10-hour shifts. This is such an important point that I have to repeat it. Adopting 10-hour shifts will reduce the coverage on each shift (except for the periods of overlapping shifts). Since part of this coverage provides a cushion for absences, the 10-hour shifts will result in much higher levels of overtime.

Absences

Some people believe that 10-hour shifts will reduce absences. Since the longer shifts provide one additional day off each week, this time can be used for doctor's appointments or other personal business. I am not aware of any studies that confirm this, but it seems possible. The Shift Length Experiment prepared by the Police Foundation did not report any significant reductions in sick leave when switching to 10s (http://www.policefoundation.org/publication/shift-length-experiment/). If there is an impact, it is undoubtedly small. 

Conclusions

10-hour shifts are universally popular with the officers. Chiefs or Sheriffs are aware of this, but lack of resources to make the change. From what I've seen, it's primarily the larger departments that have adequate resources to adopt 10s. Smaller departments (less than 30 officers) rarely have enough personnel.
