Not surprising since the teachers are not allowed to discipline them and the schools are not allowed to expel the worst students. Back in my school days, if you acted up, the teacher or principal would literally bust your a$$. And if you dared to threaten or strike a teacher, you were permanently thrown out of school. No “alternative school” where you continued your bad behavior with a different teacher. Just expelled. Bye! Sia-nary! Gone!
If you go on YouTube, you find plenty of horror stories of teachers who have quit. The basic story is its due to a combination of low pay, insane rules and unreasonable demands for documentation by school administators, increasing feral children, an inability to discipline & maintain order in the classroom (thanks to the rules). Further, there are no real consequences for kids acting up, even if they injure a teacher.
Again, I don’t blame good people for fleeing a madhouse. Unfortunately, the only teachers left are the ones who are batsh!t crazy themselves.
