I see this thread will roll out the usual anti teaching brigade. Anyone who has taught will know that you pay for your summer off in your own blood because by June most teachers are ready for the mental home.
In fairness, that's not been my experience at all. I have a cousin, primary school teacher, and he and his primary school teacher buddies travel the world for three months each year, making pigs of themselves. We're talking all the hellhole tourism spots; South America, Asia, etc. They live like Men Who Would Be Kings.
They're anything but looking to come back.
