There isn't really an inherent problem with the T&Cs at Erbil. First, several people who have put their time in (a long time, in fact) have recently decided it's time to return home. Second, of course some people arrive in places like this and have underestimated the cultural differences from home (wherever that might be) or just plain miss home more than they thought they would. Others adapt and thrive in a place like Erbil (which is not a bad place to be; certainly not at all like most people's current impression of Iraq in general).
So, in short, the turnover rate in Erbil is not higher than other similar posts, nor higher than anticipated.
