It’s absolutely possible, and schedules can skip any number of weeks. It will take a little bit of configuring, but it’s not hard.
Schedule A is a basic schedule of 2 days on, and in the ‘Repeating’ section turn on “Alternate”, set to weekly, with one week on, one off, starting in week 1. Schedule B is also a basic schedule, 3 days on, repeats alternate weeks, starting in week 1. Schedule C is again a basic schedule, 2 days on, repeats alternate weeks, but starting in week 2, not week 1.
Now you’ll need to make a composite of these schedules. Since a composite can have only two other schedules, we’ll first make a composite AB which is schedules A and B. Then we’ll make a composite ABC, which is a composite of the composite AB and the basic schedule C. Your employees then get this composite ABC as their schedule.
