TP,
If you are seeking advice, I am sorry to inform you that here on Pprune you will only get sarcastic remarks from pilots who do not have a clue about the real world.
I am afraid you have to make an informed decision about moving to Dubai on your own.
I sugest you visit Dubai for a vacation and talk to people who live here to arrive at your own informed opinion of the place.
There are a lot of pilots who have been working for Emirates for over twenty years and most are quite happy here. As far as I know all the people you find bitching about Emirates here, continue to work for Emirates for some inexplainable reason.
If you have some company that these unhappy people would find better to work for, you should let them know so they may be relieved of their suffering.
I personally think there is no perfect place or company, and at the moment Emirates is probably the best company to work for in the long term.
