Britannia (or Cambridge as they refer to themselves, and often claim direct affiliation to Cambridge University rather than just the use of the teaching materials) continues to have a shocking reputation in Kurdistan for the way in which they treat their staff - I can't say about the standard of education, though. Although Erbil is the regional capital, it's a small town for efl teachers and word has gotten around (I haven't worked for them). I've heard of at least one verifiable case of a staff member being unpaid a considerable amount, there are rumors of a member of staff being assaulted by one of the managers a couple of years ago. I know one person who worked for them without too much trouble for over a year though, so it can't be ALL bad. Certainly they are known for slandering teachers who leave, so I found their response to this with the link to a libel website very funny!
