When did/are you cutting back at work?

Just curious as a ftm when you other mama's cut back your hours (If at all) or are planning to cut back at work? I'm a teacher in a long term assignment that is getting cut back to half days starting next week and I am thinking it'll be nice to have a shorter day. I'm 29+3 and dragging my feet all day every day... seems like I just can't sleep well enough to feel rested plus the hip and back pain from side sleeping. Anyone else going through this?
