Well, it depends where you are working. The conditions you are under now. Is your wife working and kids happy. I know it is hard to resist the magic of Emirates.
Go do the interview. If possible spend a few days here before or after. Have a good talk with the recruiters. See if your family would like it. Only then decide.
Be careful reading the posts in here. They are very biased. Look at it this way. There are other jobs out there, but they prefere to sit under a palm tree and bitch. Remember no job is perfect. No employer your friend. Your contract is changed every now and then, without telling or asking you. That is one of the harder things to accept. One the other hand the sunshine is guaranteed and the tax office is hard to find...for now!
It is a personal decission. Good luck
