There are lots of reasons why people choose to move back to the UK, even if being abroad has been good. My brother has just gone back after some time in Europe ..put his CV online at CV library and got calls from loads of agencies and recruiters. He got back to England last Wednesday and has had two interviews already (with callbacks for a second interview for both) and three interviews lined up for next week. He's not a shortage subject teacher, but is flexible as to location. I'm not sure that anyone who only has private school experience could cope with some comprehensives, but, I have to say that a money grabbing, results driven international school can also turn you into a bit of a robot. Also, there are lots of new training intiatives for 14-19 yr olds and a big shedload of supply work as far as I can see. Don't fancy it myself though.
