Mate, in my view the majority of them (beaurocratic managers) can't make in the class room and get out as soon as they can. Get into a non-teaching managerial position and then just try and work their way up the ladder with no real regard for those that are actually teaching - at the chalk face.
This is not the place to express my true feeling but I'm sure you get the idea.
Only two things are need to succeed in teaching, a. a sense of humour and b. getting a true buzz out of the students, especially kids.
A terrific job stuffed up by politicians.
End of rant.
pip pip
well getting there
