8-Hour Shift Schedules for 24/7 Coverage
July 11th, 2023 at 3:18 pm   starstarstarstarstar      

A majority of the organizations that cover 24/7 use 8-hour fixed shifts. That would be fine if it weren't for the fact that employees hate the schedules. The universal complaint is that they don't get enough days or weekends off. They simply want a better work-life balance.

 

The employees think 10-hour shifts would be a good choice, but the increased staffing requirements prevent most organizations from adopting them. Most employees don't want 12-hour shifts, though when they see actual examples of 12-hour schedules, they often change their minds. But let's focus this article on 8-hour shifts.

 

There are a lot of different patterns with 8-hour fixed shifts. Unlike 12-hour schedules that normally use 4 crews, 8-hour schedules can use anywhere from 6 to 27 crews. The number depends on the coverage levels, as shown in the table below:

 

Coverage Staffing Total Average* Weekends Possible  Pattern Pattern Pattern
Per Shift Per Shift Staff Hours/Week Off (max)** Patterns #1 #2 #3
                 
1 2 6 37.3 1/2 2 Max. 7 days Max. 4 days  
                 
2 3 9 37.3 1/3 3 Max. 8 days Max. 7 days Max. 4 days
                 
3 4 12 42 1/4 5 Max. 7 days 6-on-2-off Max. 5 days
3 5 15 33.6 2/5 2 Max. 7 days Max. 5 days  
                 
4 6 18 37.3 1/3 3 Max. 7-8 days Max. 5 days 4-on-2-off
                 
5 7 21 40 2/7 2 Max. 7 days Max. 5 days  
5 8 24 35 3/8 1 5-on-3-off    
                 
6 8 24 42 1/4 5 Max. 7-8 days 6-on-2-off Max. 5 days
6 9 27 37.3 3/9 1 Max. 7 days 6-on-3-off  
                 
* Average Hours/Week often can be increased to 40 by requiring occasional extra coverage  
** Max. Weekends Off can only be achieved with certain patterns      

 

Are you thoroughly confused? Sorry. There's a lot of information in this chart. Let me try to explain using 5-person coverage as an example. There are 2 rows with 5-person coverage. On the first row, 7 people are required if they work an average of 40 hours a week. On the second line, 8 people are required, but they only have to work an average of 35 hours a week. 


Why would you adopt a schedule that only averages 35 hours a week? People do it all the time. Not because they want fewer hours. They chose a popular work pattern without realizing that it averages less than 40 hours. In this case, the pattern is 5 days of work followed by 3 days off, aka 5-on-3-off.

 

Continuing with the example, you'll next see the maximum weekends off. The maximum with 7 people per shift is 2 weekends off every 7 weeks whereas the max. with 8 people per shift is 3 weekends off every 8 weeks. After that is a tally of the number of possible schedules along with descriptions of those schedules. Max. 7 days means the schedule requires working 7 consecutive days at some point. In general, the more days worked, the more weekends off.

 

A significant portion of my clients contact me because they have adopted a popular 8-hour work pattern, and they're tired of the employee complaints and never having enough or consistent coverage. I try to show them both alternative approaches (i.e. different shift lengths) and other 8-hour options. This way they can compare the coverage, average hours of work, weekends off, and so on. This chart illustrates the possibilities for 8-hour fixed shifts only.
