When I was in Jr. High we had a male teacher that used to slam kids up against the wall. I was told one parent complained but nothing was ever done about it. Today he’d be sued into oblivion.
In all fairness he was a jerk. He tried teaching at the local college and lost his cool there. They booted him.
In our school, the men teachers took the problems guys out in the hall. The women would go get a shop teacher. There were a few boys bounced off lockers. Never saw it, but we heard it. That said, school was safe for us and we knew it.
