I am working in a Karela company in here. According to the Qatar government policy the working hours is 48 hours. But we are working 72 hours in a week. I am working this company for last 10 month. When I am asking for raise my salaries they ask me to change my sponsorship. I am working this company with letter. For last 10 month i work 800 hours where even a single dirham of my overtime was not paid. Asking for help to anyone.
