Some of the teachers were hired back in August. The school dragged their medical tests and benefits to see if they like the teacher for the 1st tri-semester. Some of the teachers are miserable on their housing arrangements. Others complain about being put on inside contracts and receiving no plane ticket back home or any tuition allowances for their children. Some of the employees didn't receive their salary until they cleared their medical examination. Therefore, you basically worked for FREE until you received your Qatar ID.
If a woman is hired usually she can not sponsor her husband. So read the fine lines before you get here.
