>all govt school teachers need to be fired.
Not all do. Best ones find a school with a decent principal and keep a low profile. If your a moderately good teacher and can coach, without having advanced degrees out the ass, you can get a job anywhere. Very mobile. Best for your own kids, too. Find the best school for them and get a job teaching in the district. A lot of small rural schools are good to work at. Best principals are former coaches; not threatened by and operate wisely with conflict.
Assholes like this teacher are what's left over when all the good ones have left for better pastures.
