I for one, would not wish to be school teacher these days for quids, and I know quite a few of them.
It is my opinion that so many of the problems encountered, stem not from the school itself, but from the family home.
One particular friend who was teaching year 10, said that on many occasions if he had to pull a boy into line, the next he knew was the father coming to the school wanting to punch the crap out of him, and on one occasion being threatened with a knife. Fortunately, when the parent was faced with the size of this bloke, the threats fizzled out.
By parents getting involved in this way, the kids have no respect at all for any authority. He added that his most successful students seemed to come from homes which had a loving environment, allocated responsibilities and fairly firm guidelines.
Back when I was at school, we had teacher who'd been a Regimental Sergeant Major in the army for many, many years, and struck a lot of fear into the kids if they were not doing the right thing. I too got a few wacks with the stick he carried, but he was always fair, though very tough. When he died some years later, it was absolutely amazing to see who turned up at his funeral. There would have had to have been at least two dozen of who had been the schools biggest tough-nuts from the slum area that was nearby, who'd come to pay their respects to him.
That was a very memorable moment, which indicated that his discipline had taught love and respect.
RIP Ernie, you tough old bastard. You did well.
