How do I setup Snap Schedule for a 24/7 work schedule with 8-hr shifts? I have 9 employees working 4 days on, 2 off. They work 8-hour shifts, 24/7, fixed schedules. Over a six-week work schedule, each one works 40 hours per week for 4 weeks and 32 hours per week for the remaining 2 weeks.

Before we start designing a schedule plan for this work schedule, let’s us look at the constraints imposed by the days on/off sequence. Given the 4 days on and 2 days off rule, there are 3 combinations of days on/off that meet this requirement as shown below.
8-hr Shifts, 24/7, 4 On 2 Off Work Schedule - shifts and rotation patterns

Using three 8-hour shifts, we have 9 unique shift patterns that the employees will follow (3 shifts x 3 combinations of days on/off). For fixed shift plans, employees cannot rotate among different shifts so each shift must be staffed independently. The number of teams (a group of employees who follow the same schedule) required by this schedule plan is 9, one team for each unique shift pattern. We have 9 employees so we will assign one employee to each of the 9 teams. Note that only 6 employees will be working on any given day while the remaining 3 employees will be off.

Because we want the scheduling period to be 6 weeks (42 days), there are 7 legs in the work schedule (42 days / 6-day patterns). In this work schedule, each employee will return to his/her original schedule after six weeks as shown below. Note that we could easily have a 6 days scheduling period due the nature of the shift pattern.
