mac is very flexible with scheduling. I think it all depends on who your managers are and what not, but mine are awesome with that. MAC totally supports you going to school. I'm a 24 hour a week position, and the manager who does the schedules always asks me what times I go to school and what days i need off and what not before she makes the schedules. there's lots of positions all the way from 10, 20, 24, 28 hours... ect.
