What Desert Knight meant to say was:
There are plenty of pissed off people due to current rostering practices, lack of pay increases, unilateral changes in conditions. But the sad reality is that this is still one of the best expat jobs going. That is not an endorsement of this job, but a reflection on how crappy the other jobs on offer are. That is one of the reasons not too many are leaving.
It is my guess that the situation isn't going to change any time soon. So I don't think you will see many guys leaving for greener pastures, because I dont think they exist.
