This is the second post in a series on the subject of fatigue. In each post, I will focus on steps that management can take to address fatigue.
In the first post, I noted that employees don't think they need more than 7 hours sleep. Managers may want to post articles explaining the impact of sleep debt and the need for more than 7 hours of sleep a day. Just run a Google search for "sleep debt" and copy of few of the articles. If you can find anything by William Dement, he is the subject matter expert. I doubt that doing this will change employee behavior, but it may help to justify any actions management undertakes to address fatigue.
This post draws from a previous post in which I showed how early shift start times reduce the average hours of sleep for day shift workers (http://www.shift-schedule-design.com/Blog?m8:post=problems-with-early-morning-start-times). To summarize, people who start work at 7 a.m. sleep about 20 minutes more per night than those who start a 6 a.m.
Changing shift start times is difficult because people build their lives outside of work around the shift start and end times. When I review employee surveys, they often list the pros and cons of early start times. They say that the best thing about their current schedule is that they get off early, giving them time to do all sorts of things. Then they turn around and say that the worst thing about their schedule is having to get up so early and always feeling tired. How do you resolve this dilemma? It's both the best and worst features of your schedule - at the same time.
The other consideration with shift start times is traffic congestion. Later shift start times may require employees to spend extra time commuting. This takes time away from other activities. For those "other" activities to continue to take place, sleep is often the first thing sacrificed. Although many companies flex their hours to allow commuters to minimize time spent in traffic, this can be challenging for those with shiftwork operations.
Early start times affect more than just shift workers. I've seen articles about the impact of early school start times on student performance. Teenagers have an internal clock that makes it difficult for them to be alert early in the morning, suggesting that learning would improve if schools started at 9 a.m. instead of 8 a.m.

I just got an email from someone searching for a 10-hour rotating shift schedule for a company that worked 18/7. He needed 2-person coverage on the day shift and 1-person coverage on the evening shift. I gave him a quote of $150 for two different options. His reply was: "I’m sorry Bruce, I'm not paying $150 for the schedules. Is there anywhere you can point me to find something similar online. Had a hard time finding anything until I came across your ad."
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.

[Please note that a similar version of this appeared in Industry Week. It was written by Bruce Oliver and Dan Capshaw]
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.

As a general rule employees prefer fixed shifts and employers prefer rotating shifts. You can read more about the pros and cons of each approach here: Fixed Shifts vs. Rotating Shifts.
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.

I've never seen statistics on this but, based on the inquiries for scheduling help I've had over the past 20 years, it appears that a majority of the companies that cover 24/7 use 8-hour fixed shifts. One big reason they never switched to 12-hour shifts was because their workload varied in 8-hour increments. They needed more workers during the daylight shift(s) or, in the case of police, paramedics, and call centers, they needed more workers during the evening hours, especially on Friday and Saturday.
These companies don't realize that it's possible to adopt a schedule with both 8 and 12-hour shifts. You simply create a 12-hour pattern that covers 24/7 and provides the coverage needed on the shift with the lowest workload (usually the night shift). Then you overlay that with one or two 8-hour shifts during the busier times of the day.
Here's an example. Suppose you need 4 people working from 8 a.m. to 4 p.m. and 2 people at all other times. You would adopt a 12-hour schedule that produces 2-person coverage on both shifts and overlay that with a single 8-hour day shift that produces 2-person coverage. The combination produces the exact coverage needed: 4 people from 8 a.m. to 4 p.m. and 2 people from 4 p.m. to 8 a.m.
Here's another example. You need 4 people from 7 a.m. to 10 p.m. and 2 people the rest of the day. You would use a 12-hour schedule with 2-person coverage on both shifts. Then you would overlay that with two 8-hour shifts, each with 2-person coverage. That would give you 4-person coverage during the entire busy period.
Employees don't really like 8-hour schedules. They don't get many days off, they have to work a lot of consecutive shifts, and most importantly they don't get many weekends off. Why not give some of the employees a better schedule using 12-hour shifts. Not everyone will like the 12s, so they can stay on one of the overlay shifts. This seems like a perfect solution. You're not making everyone switch to 12s, and you're offering an option to improve work-life balance for those willing to change.
Why don't you give us call to see how this might work for your organization? We can show you a few different options with all 8-hour shifts as well as a few options with both 8 and 12-hour shifts. Click on this link and fill out the form to get started: Request Quote

During the coronavirus pandemic, organizations that employ first responders and critical workers want to minimize the risks associated with both public and employee interactions. Here are some scheduling strategies that can help:
Public Interactions
First responders and critical workers who are in close contact with the public, especially with people who might have virus, face a unique challenge. Their repeated exposures increase the chance of getting sick and not being able to perform their duties, or even worse, spreading it among their co-workers. How can managers of these frontline workers address this risk?
One approach would be to gradually rotate the staff through a 2-week furlough, so there's a reserve staff that hasn't been exposed to the virus. And, even if they have been exposed, keeping them away from work for that long will reduce the risk of spreading the virus to fellow workers.
In 24/7 operations, this can be done by adopting a 5-crew rotating shift schedule. If the organization is already on a 4-crew schedule, it would have to shrink the size of the crews by 20% to create 5 smaller crews. Here's an example of what this schedule would look like:
Crew / Week
Mon
Tue
Wed
Thu
Fri
Sat
Sun
Hours
A / Week 1
N12
N12
N12
N12

48
B / Week 2
-

-
D12

E / Week 5
D12
-
-
-
D12
D12
-
36
Average
33.6
Key:
D12 = 12-hour day shift
N12 = 12-hour night shift
The way the schedule works is that each crew (A, B, C, D, and E) starts the schedule in the week shown next to them. After finishing the initial week, they rotate to the next week of the schedule. Crew A moves from Week 1 to Week 2, Crew B moves from Week 2 to Week 3, and so on. Crew E moves from Week 5 up to Week 1. All five crews continue rotating through this 5-week pattern for as long as needed.
Notice that there are 14 consecutive days off from Friday in Week 1 to Thursday in Week 3. This is the 2-week furlough mentioned above. If you only pay for the hours worked, the employees will average 35.2 hours a week when you factor in the overtime from the two 48-hour work weeks (Weeks 1 and 4). If you pay for an extra 40 hours of vacation time during Week 2 of the schedule, they will be paid an average of 43.2 hours a week over the 5-week period.
Employee Interactions
The secondary concern of these organizations is having sick or exposed employees spreading the virus to other employees. Here's an article I saw regarding this: https://shift-work.com/news/news/11-steps-you-can-take-today-to-keep-your-employees-safe-and-your-shift-work-operation-going/
As this article states, 24/7 operations can temporarily switch to using two 10-hour shifts that are separated by 2 hours each. This will minimize contact during shift turnovers/handoffs, and it frees up time that might be used for cleaning and sanitizing. This may not be practical for smaller groups, but the concept has merit and maybe can be modified to suit your unique circumstances.
How do you come up with a 10-hour schedule with only 2 shifts a day? Simple. You adopt any 12-hour pattern and replace the two 12-hour shifts with two 10-hour shifts. You could adopt the 5-week pattern shown above or any other popular 12-hour pattern that uses 4 crews.
If anyone comes up with other scheduling work-arounds during this pandemic, please let me know and I'll try to pass them on. Thanks.

Thank you for your service, Public Safety Dispatchers! I saw this bulletin in my Nixle from the Petaluma Police Dept. I thought it was worth repeating.
The week of April 14 - 20, 2019, is "National Public Safety Telecommunicators Week." This is an opportunity to honor the women and men who serve as our Public Safety Dispatchers. Telecommunicators week began in California in 1981 and quickly grew to national recognition. Just ten years later, Congress designated the second full week of each April as a time to remember the critical role Dispatchers play in keeping us all safe.
Dispatchers are the voice at the other end of the 9-1-1 call assisting a distraught caller and at the other end of the radio when police, firefighters, and medical personnel are responding to emergency situations. If you've ever been the victim of a crime, been in a collision, reported a fire or needed emergency medical help, you've called 9-1-1 and been helped by a Telecommunicator, also known as a "Dispatcher."
Not being visible or always recognized in the public eye, the critical role they play between the community and first responders is essential for every public safety call for service. Our Dispatchers are the direct link to our officers in the field. They monitor the radios, computers, phones, and more, answering thousands of calls from our community each year.
Please join us in this week as we say THANK YOU to the often heard but not seen, first of the first responders, our 9-1-1 Dispatchers.

Google searches for “Shift Schedule Templates,” will reveal page, after page, after page of software programs. Unfortunately, and to most people's surprise, these programs won't create schedules for you. You have to enter each employee's on-off work pattern into the program to make it work. Some scheduling programs offer free schedule templates, but these are generic 8-hour or 12-hour shift schedules, best suited for large companies with steady workloads.
Smaller organizations with limited staff and/or uneven workloads can't always use the generic templates offered by the software vendors. If they do, they may have to employ extra, unnecessary staff or live with coverage that doesn't match the work volumes during different times of the day (or days of the week). A lot of companies do this without realizing there are better options. How would they ever know?
So, if you're looking for a new schedule, don't be fooled by these scheduling software programs. They're great for managing an existing schedule, but they won't create a new work pattern for you. And for the few programs that actually offer templates, please beware of the following:
1. There aren't any templates for companies that operate less than 24/7.
2. If your staff size is not an exact multiple of 4 (e.g., 4, 8, 12, 16, 20, 24, etc.), the template will not produce consistent coverage. That's because most of them use 4 crews.
3. If your workload and coverage requirements vary by time of day or by day of the week, the template will not address this. These schedules have the same coverage at all times.
4. If your pay week (for overtime calculation purposes) is different than the template's, the schedule might produce highly uneven work hours (e.g., 60 hours one week and 24 hours the next), or it might compromise weekends off for employees.

Wikipedia defines para-transit as follows:
"Para-transit is recognized in North America as special transportation services for people with disabilities, often provided as a supplement to fixed-route bus and rail systems by public transit agencies. Para-transit services may vary considerably on the degree of flexibility they provide their customers. At their simplest they may consist of a taxi or small bus that will run along a more or less defined route and then stop to pick up or discharge passengers on request. At the other end of the spectrum—fully demand-responsive transport - the most flexible para-transit systems offer on-demand call-up door-to-door service from any origin to any destination in a service area. In addition to public transit agencies, paratransit services are operated by community groups or not-for-profit organizations, and for-profit private companies or operators."
Because the demand for para-transit services is so highly variable, scheduling the drivers is a challenging task. Most para-transit organizations tend to rely on overtime and a large pool of drivers that can be called into work when needed. I believe there is huge opportunity to schedule the drivers more effectively and reduce the costs. This opportunity comes from two key points. The first point is that historical trip volumes can and should be used to develop a schedule. The second point is that relief coverage is the best way to accommodate both employee absences and deviations from historical average trip volumes. Let's take a closer look at the specific steps involved.
Step #1: Historical Trip Volumes
The first step is to determine the workload distribution throughout the hours of operation. Start by categorizing the trip data into 2 or 3 groups based on the time involved. For example, Category A consists of trips that last 30 minutes or less. Category B consists of trips that last 30 to 60 minutes. Category C consists of trips that last more than 60 minutes.
Then look through the past year's historical data of trips made during every 30 minutes of the hours of operation. So if the first trip of the day begins at 6 a.m., I would calculate the average number of trips in each category between 6:00 a.m. and 6:30 a.m. Then I would do the same for 6:30 a.m. to 7:00 a.m., 7:00 a.m. to 7:30 a.m., and so on. I would put these averages into a summary table.
If you have the data (and the time), you could also determine the maximum number of trips that occurred during each 30-minute period and add this data to the summary table. You also could create separate tables for each region in the service area and for each season of the year.
Step #2: Driver Requirements
The second step is to determine the coverage requirements. The number of drivers needed during each 30-minute period depends on the type of service the organization offers. If the service is door-to-door, you will need one driver for each trip. If the service is limited to fixed routes, you will need fewer drivers per trip. The point is that you will need to translate the trip volumes into driver requirements by time of day. In scheduling jargon, this is called establishing the coverage requirements. Once these figures are made available, a scheduling expert can help with the remaining steps. I say this because the next few steps are the most difficult part of the process.
Step #3: Schedule Framework
This step will determine the shift lengths, start times, and number of drivers needed on each shift. This is basically a trial and error process. Here is a simple example:
Time Period Drivers Needed
0600 to 0700 5
0700 to 0900 6
0900 to 1300 8
1300 to 1500 7
1500 to 1800 5
You begin with the first time period of the day (0600 to 0700). 5 drivers are needed on this first shift. You can test the three standard shift lengths: 8-hour, 10-hour and 12-hour shifts according to how well they fit with the afternoon requirements. If we use a 12-hour shift, this will means 5 drivers will be working from 0600 to 1800. This matches the coverage needed from 1500 to 1800, so that would be the best choice. For most organizations, it's never this simple and compromises (e.g., over-staffing for part of the day) are likely to be necessary.
6 drivers are needed during the second period (0700 to 0900). We therefore will need 1 driver on this second shift (since we already have 5 people at work from the first shift of the day). Again we will test the three standard shift lengths for the impact on the afternoon. The best choice would be an 8-hour shift since anything longer would unnecessarily boost the coverage after 3 p.m. when it isn't needed.
We continue this process, sometimes going back to the beginning and changing earlier choices to make the entire framework more efficient, i.e. no understaffing and minimal overstaffing. The framework I would choose is as follows:
Shift Length Drivers Time Covered
12 5 0600 to 1800
8 1 0700 to 1500
4 2 0900 to 1300
If part-time drivers are not allowed in an organization, I would choose the following framework:
Shift Length Drivers Time Covered
12 5 0600 to 1500
8 3 0700 to 1500
Step #4: Basic Staffing Requirements
Now that we know the shift lengths and coverage requirements, we can determine the number of drivers needed to produce the coverage requirements. The 12-hour shift will require 10 drivers to produce 5 drivers every day of the week. The 10 drivers will all work an average of 42 hours a week. The 8-hour shift will require 2 drivers to produce 1 driver every day of the week. They will average 40 hours a week and there will be 3 days a week in which both drivers must be scheduled to work (to ensure 40-hour work weeks). If you can use part-time drivers, you can avoid the days of overlap. The 4-hour shift will require as many part-time drivers as you want.
Step #5: Supplemental Staffing Requirements
In the previous step, we focused on the staff needed just for the coverage requirements. But remember, the coverage is based on the average number of trips, not the peak demand. Also, drivers get sick, take vacation, or change jobs. That means we need some extra staff to allow for this. If we assume a 10% absence rate and another 30% difference between the peak demand and average demand, we need a 40% relief allowance.
In addition to the extra staff needed for relief coverage, some of the shifts will need extra personnel to simplify the schedule design. Here's a summary of the staff needed for each shift:
Shift Basic Staff Relief Staff Extras Total Staff
0600 to 1800 10 4 1 15
0700 to 1500 2 1 0 3
0900 to 1300 2 1 1 4
Step #6: Schedule Design
For the 12-hour shift, we will create a 3-crew schedule (5 drivers per crew) that averages 42 hours a week. For the 8-hour shift, we will create a 3-crew schedule (1 driver per crew) that averages 40 hours a week. For the 4-hour shift, we will create a schedule that averages 20 hours a week. We will use the staff on this part-time shift as trainees and reserves for full-time employees that decide to change jobs.
Here is an example of a schedule for the 12-hour shift:
Crew/Week Sun Mon Tue Wed Thu Fri Sat Hours
A / Week 1 - 12 12 - - 12 12 48
B / Week 2 12 - - 12 12 - R 36
C / Week 3 R R R R R R - 42
The three crews of 5 employees are assigned to one of the 3 weeks in the cycle. Crew A is assigned to start in week 1, Crew B is assigned to start in week 2 and Crew C is assigned to start in week 3. At the end of each week, the crews move to the next week of the cycle: Crew A moves to week 2, B moves to week 3, and C moves up to week 1. They continue to move through the 3-week cycle. All three crews are working the same 3-week schedule. They are merely in different weeks of the 3-week pattern.
R is a relief shift which means the crew is on-call for the entire 7 days shown. If someone from week 1 or week 2 is scheduled for vacation, an employee on relief will simply work the vacationer's schedule that week. If no one is absent, the employees on relief can be called in for a couple of hours to satisfy a temporary increase in demand. The organization should establish rules on the priorities for relief work and limits on the hours and number of days worked during the 7-day period.
Here is an example of a schedule for the 8-hour shift:
Emp / Week Sun Mon Tue Wed Thu Fri Sat Hours
A / Week 1 - - 8 8 8 8 8 40
B / Week 2 8 8 - - R R R 40
C / Week 3 R R R R R - - 40
Conclusions
We've demonstrated how assembling historical data on trip volumes can be used as the foundation for scheduling transit drivers. We also illustrated how to build extra capacity into the schedule to cover absences/vacancies and temporary fluctuations in demand. The key point is that schedules for variable workloads are ideally based on actual data rather than gut feelings, intuition, overtime considerations, etc. Using a full-time scheduling person that spends the day on the phone trying to get drivers to come to work is not the most efficient or effective approach when it comes to scheduling para-transit drivers. So if you want to keep service levels high and costs low, see if we can make this new scheduling process work for you.

Your group needs a new employee work schedule. Maybe the staff size has changed. Or the demand for your product/services requires you to increase the hours of operation. Perhaps you've run out of space and need to add a 2nd or 3rd shift. Maybe you're just tired of listening to employee complaints. Whatever the reason, you know that something has to be done.
If you're like most managers in this situation, you may be asking friends or associates in your industry about their schedules. And you're probably searching the Internet for additional ideas. It's important to find a solution that doesn't require a lot of time or money. Your regular responsibilities can't be put on hold and your budget has little room for unexpected expenditures.
Unfortunately, a schedule that's not tailored to the organization's hours of operation, coverage requirements, staff size, and pay week will rarely be a good solution. You will probably end up with problems such as these:
Ineffective coverage
Inconsistent coverage
Over-staffing
Unnecessary overtime
Minimal weekends off
Let's look at each of these problems a little closer.
Ineffective Coverage
The fundamental purpose of the schedule is to ensure the right number of people at work during all the hours of operation, i.e., to match the coverage with the workload.
If the work volume is fairly steady, then the coverage also should be constant. A schedule with hours of overlapping shifts would be ineffective for these situations. For example, using 10-hour shifts in an organization with a steady workload would be a waste. There is no need for the 6 hours of double coverage while the shifts overlap. It would also be costly, since it would require 25% more personnel than a schedule using 8-hour or 12-hour shifts.
If the work volume varies by time of day or day of the week, the coverage should reflect that. Possible solutions include mixed shift lengths, overlay or power shifts, 10-hour shifts, staggered shift start times, or different coverage levels on each shift. An example of ineffective coverage is a police department with a heavier workload on Friday and Saturday evenings that uses a schedule with the same coverage throughout the week.
Inconsistent Coverage
An ideal schedule consistently matches the desired coverage. Some schedules don't do this. Here are two examples:
Sometimes companies have more staff than the minimum necessary. They may have reached this position because they were using an inefficient schedule which required more employees or they thought the extra personnel would help to cover absences. A small food processing firm needs 5 people working on a 24/7 basis. They employ 23 people, three more than the minimum necessary. They could have used the extra employees to build relief coverage into the schedule, but instead adopted a schedule in which the coverage varies between 5 and 6 people.
Sometimes organizations adopt schedules that produce fluctuating coverage because they like the work pattern even though it is a poor match for their requirements. For example, a warehouse needs at least 3 people working around the clock. They chose a schedule with a 6-on-3-off pattern because their employees thought it would be better than the current schedule. Because of their staff size, however, the coverage varied between 2 and 3 people. To maintain the minimum coverage levels, the company was forced to hire 3 more employees. The coverage now varies between 3 and 4 people. In this case, choosing the wrong schedule increased their costs by 25% and it is still producing inconsistent coverage.
Over-staffing
Nobody wants to overstaff, yet it happens all the time. It occurs primarily for three reasons:
The organization sets an annual target of less than 2,080 work hours per employee (<40 hours a week). For example, a police department has a labor contract that limits employees to 1,820 hours a year. This is an average of 35 hours a week. They need 5-person coverage using 10-hour rotating shifts. Because of the reduced work hours, they have to employ 30 officers. If they worked an average of 42 hours a week, they would only need 25 officers.
The organization builds extra coverage into the schedule rather than using relief coverage. For example, small utility needs 4-person coverage at all times. Although they could do this with 16 people working an average of 42 hours a week, they employ 20 people to have 5-person coverage at all times. They could have employed 17 people (rotating shifts) or 18 people (fixed shifts) and built relief coverage time into the schedule which would have accomplished the same thing.
The organization wants a schedule with no built-in overtime. A small hospital needs 3 CNAs on a 24/7 basis. Their 8-hour fixed shift schedule requires at least 12 people working an average of 42 hours a week. However, they are instructed to eliminate overtime from the schedule. To maintain the same coverage, they are forced to employ 15 people at 40 hours a week.
Unnecessary Overtime
People adopt work patterns that were intended for a different pay week. If they don't tweak the schedule, they could end up with highly unbalanced work weeks and more overtime than necessary. Example: A small trucking company found a schedule that was intended for a Sun-Sat pay week. Since their pay week starts on Monday, the employees work 60 hours one week and 24 hours the next, and the company has to pay for an extra 3 hours of overtime per employee every week.
Minimal Weekends Off
Employees want to get as many weekends off as possible. This may not be achieved if the organization chooses the wrong schedule or doesn't modify it to fit their pay week.
A nursing home has a schedule with several split weekends in which employees work either Saturday or Sunday instead of both. A different pattern would have provided more full weekends off.
Many work patterns work best for a certain pay week. For example, a popular 8-hour rotating shift schedule pattern that requires only 4 or 5 consecutive days of work provides 1 weekend off every four weeks - only if the pay week begins on Sunday. Trying to use this pattern with a Monday start will mean the workers never get a full weekend off.
Conclusions
When organizations select a schedule that is not matched to their specific resources or requirements, employees can suffer from fewer full weekends off and the organization can suffer from ineffective coverage and higher costs.
