My wife's a teacher. Parents are insane. Schools/admin don't push back much. If you're lucky they're just up your ass—"Why does my kid still have a 0 for this assignment in the online gradebook? They turned in their late paper at 10am and it's 3pm now and you should have gotten to it in your 1 hour plan time, and you should have returned my stupid call that I never should have made, nevermind you have literally 100 other kids to worry about and you send weekly updates on all kinds of stuff that I don't read". That kind of crap. If you're not lucky they're the sort that loudly accuses every teacher their kid has of racism every year within the first month of school.
