My partner wanted to help kids out, and did while they were there (and a bit after), but...they just burned out. Too stressful dealing with ridiculous parents, insane testing demands, demands from admin boards detached from the current reality, and atrocious pay.

They started working before I did on a given day, finished grading and working around the same time or later than I did, made far less and were far more stressed the entire time.

And they WANTED to help; nobody is gonna want to do a job that pays like shit, treats you like shit, and works you to death.
