Don't go back if you can avoid it! I worked in Dubai back in 2001-2003. I came back to Britain and went on supply as I could not get a job from abroad (they will not give you a telephone interview and expect you to foot the bill for a plane flight back for interview) Although I have long since settled - I came back to get married- I feel that I should have stayed abroad. Why? Teaching in Britain is a VERY HARD job compared to teaching abroad. In Dubai, I had nothing like a discipline problem, was left alone to teach and felt very little scrutiny apart from what is fair - the termly observation by the HOD and generally, the atmosphere was conducive to actually enjoying your job! In Britain, almost the exact opposite is the case. You are always being asked to justify everything you do and it is mostly a demoralising experience. Stay abroad, unless you are a glutton for punishment!
