I too have several friends there employed as 'consultants' and they say their deal sucks compared with what the permanent guys get, despite the fact that the 'consultants' do all the flying and the permanents do all the golfing.
The money as a 'consultant' is not that wonderful and if that's what you've been offered you'd get around the same pay, better flying and a much better quality of life with either Gulf Helicopters or Abu Dhabi Aviation. Several guys who left the Emirates returned after only a short time with Saudi Aramco.
