It actually sounds like things are getting better. When I was in school, there were a couple of incidents in which teachers were fired for less than that. No hearings, no appeals. They were just gone the next day. One that I recall was a teacher, in response to a question about some mysterious matter of girl physiology, loaned one of her college health textbooks to a girl for a weekend. The parents discovered the "dirty book" and the teacher was gone by Tuesday.
Meanwhile, we had a couple of utter imbeciles teaching at the high school, solely because they were members of the principal's church. To all appearances, one of them was functionally illiterate, but he had to teach something besides "coach." Unfortunately, that former principal is still leading the school board. Jeez, he must be like 80 or 90 now.
