Perhaps it is the union that keeps the school system from being able to retaliate, or it could even be stupid government laws and politically correct policies that prevent teachers from taking matters into their own hands.
Most of your examples of such treachery, I have observed, seem to be based on fiction stories/movies.
Are you saying that what I am telling you about my mother’s experiences in the public schools is fiction?
Hello, I was there.
Fiction — exactly.
Teachers, as part of the union, probably actually give up their legal right to sue the administration for most harms that evil principals may perpetrate against them.
The whole thing is a deplorable hoax.
Teachers unions? Think about it.
