I'm trying to create a morning and an afternoon shift. They should not be handled by the same person ever. The night is taken by an actual oncall schedule which is separate and works fine and doesn't need changing in this context.
But the result for me is, that the shifts don't actually align at 50% each, but get this weird fragmentation pattern, even when making two distinct slots and a rotation of exactly the hours length of the slots (which already is annoying since for us it would actually be 4.5 hours each, but even at 5 hour each it still doesn't work).
The only way I have found to get rid of those, is to have two entire schedules again, but then the system doesn't give you any option I can find to ensure both schedules aren't given to the same person, if the same people are in the pool for both schedules, which for us they are.
Does anybody have an idea what else we could do to have two daytime shifts, each assigned to one person in its entirety and not the same person for both on one day?
Attached the failed schedule fragmentation and my attempted settings.
