And when little adorable 'jonny' pulls a knife and holds the teacher hostage? (worse case scenario)
Or when the kids become disruptive to the teacher in such a way to warrant the expulsion, but the parents pull out the lawyer card and threaten the school system with a big rowdy news report and lawsuit, I bet you, short of something life threatening, the school system is going to fold and let the kid stay or make some arrangements other than expulsion.
Reminds me of a teacher who posted in their blog how horrible their students were to such a degree they vented (in a moment of absolute stupidity) on their blog site... which got them sacked.
No word, however, on the 'horrible children' they talked about. Last heard, they were still in school. Fancy that.
The parents, generally, don't give a crap. Until it's their reputation on the line, then they solve it through the nastiest way possible that schools can either fight and lose face winning, or capitulate and hide it behind the scenes.
A lot of their money comes from the board. The money of the board comes from capitol committees where they, like the school board, have their reputations to worry about as well. You think they'll give them more cash for looking poorly? It affects their end of year bonus. Won't happen.
So, little jonny doing his threats, up to and likely including pulling a knife, very likely is being swept under the rug even as we speak at some school district in the good ol' USA.
Money talks. If you don't have it, which the majority of the teachers do not, then you're screwed.
