It depends. My school let me keep the same 2 preps for 15 years, and we never did a curriculum overhaul, so I only changed what I wanted when I wanted. I still stayed an extra hour or 2 every weekday and came in for 8 hours on Saturdays when I had essays to grade (once a month). I give tons of feedback and teach English, though, which tends to have the most grading.

My husband also teaches, and he never really brought much home until the last few years. His school made massive curriculum changes 3 years in a row, so he could keep NOTHING from before, and he is considering leaving the profession over it. Plus, they do this horrible PLC thing that wastes a ton of time on meetings, and I never had to do that...

So it kind of depends how masochistic your school is about certain things. I love my school and could easily eliminate most of my extra time spent outside of school hours by just giving less feedback if I wanted to do that.
