Ah so and you wonder why 75% & more US teachers are already stressed out. You quit but many teachers like teaching, and others do not have second vocation to fall back on. It is the other demands on them that cause the problem. And now people like you think it grand that they take on the job of body guards for between 20 to 30 students given over to them.? Even you should be able to foresee the worst case scenario in such a situation.Been a long, long time since you've been in school obviously.
I was a teacher for 7 years. I hated it, because lifting people out of ignorance was the last thing they wanted us to do.
