A lot of the jobs that are given to the foreign workers give them the opportunity to bring their family as well. When they are given accomodation, usually for free, it caters to the size of the family. Are there ever cases where the worker's family is not allowed to come or isn't necessarily supported when they come by the employer.
I have also heard that when you are working with a good firm you are provided lot of perks and accommodation is one of them.Your housing problem is solved without any effort and you see it is one of biggest benefits.The best part is that you are given an apartment as to suffice your family well.
