Unions are illegal


In order to exit the country, you need an exit pass from your sponsor - who can withhold it at will (in effect you are a prisoner) - good sponsors do not usually withhold it unless for good reason.


You can be jailed for debt here - or even passing bad cheques and you will not be allowed to leave the country without clearing loans/credit card debt etc when your job ends.


Today the weather is so bad I can hardly see across the street for the dust.


Choice of employer/sponsor is crucial to ensure they actually meet their obligations under your employment contract.  BTW regular working hours can mean 48 hours per week 6 days per week depending on your contract


Rude gestures and/or words (or those interpreted to be so by others) can also land you in jail, or at least in front of the police trying to explain yourself.


Ramadan means no eating, drinking, or smoking in public from Dawn to Dusk.


I would suggest you do more research as your OP seems very naive as to what to expect in the GCC.  As someone else said - there are other threads on this topic on this site, try looking at some of those and maybe you can ask questions more relevant to your personal situation - otherwise all we can do is give you generalities.
