If you do leave your employer make sure you get a letter of no objection - without this you wont get back into or a job in Qatar for a couple of years. I think they are changing this soon, does give employers a lot of power over employees and workers ability to move employers. If you do leave a contract early make sure its agreeable with the employer as if you leave on bad terms then they can make things very difficult if they want.
