Going back to the title of the thread, why work in Dubai?
Well, probably the best ATC pay in the world, with an employer which can be trusted to pay on time and will stand by its staff when they need hospital treatment, etc.
An exciting city, and yes it's a construction site but it's a construction site with lots and lots of great bars! Yes, the drivers are lousy but once you've bought the sports car or the huge SUV and having the reactions and skills of an ATCO, you'll be just as bad a driver as the locals. How can anyone hit you when they're all behind you, right?
You needn't worry too much about being robbed, mugged, burgled or taxed (except on booze). It's a Muslim nation that never pretends to be anything else yet gives limited rights to Christians, as opposed to all those "Christian" nations that bend over backwards to avoid the slightest offense to their Islamic immigrants while losing sight of whatever national character they once had.
Above all, a great mix of Kiwis, Brits, Sefricans, bloody Aussies, Scandanavians and assorted Europeans and North Americans, most of whom can be counted on to be good company at Friday brunch. Abide by the local laws, enjoy the lifestyle and do the work, and what's not to like?
