I do agree in general terms. Teaching maths or physics in comp must be a laugh a minute.
So, having got that out of the way, I do have a good few friends that are primary and infant teachers. They've been doing it a few years. They would quite readily describe their jobs as a well paid piece of piss the rest of us have missed a trick not getting in to. Of the ones that work down the road from my house, I know when they are in school, because they get to park their convertible, discovery and cooper s for free on the premises. The cars are never there when i leave for work, they are never there when I get home. But don't get me wrong, I love them to bits and they use their ample free time to help run several voluntary groups such as a community garden and a food bank etc.. oh, and I've just given one of them a Triumph Spitfire, because he has the time and money to do it up, and I don't.
