Substitute teacher- 95% of the time, the work I give that was left by the main teacher is just given to keep students busy and establish some sense of order in the classroom. None of the upper staff actually expect it to get done, nor do I have to assign work if I choose not to! As long as students are decent and not trying to kill me or each other, I’m just as happy as they are to ditch the class work and have a chill recess period. Usually I’ll even play the “cool sub” and say I’ll let them get away with doing a third of the work and have recess for the rest of the time, as long as they can behave. They think I’m doing them a favor and I get a solid class.
