An old friend and colleague of mine left to teach in a school in Vale Colorado and he thought the conditions were better over there, but he was into snowboarding and mountain biking etc so I think the lifestyle and opportunities he had made a big difference to him. Think he's left teaching in the classroom now in favour of something else to do with education though.I have many teacher friends that I've made over the years. Mostly disenchanted angry people. But that sounds like most of my friends.
Maybe all teachers should have sheds where they can hide - or padded cells where they can have a good scream.
