Hello! My employment visa was for 1 year. And...

It should be noted that after reviewing your inquiry and legal scrutiny we would like to inform you that the law gives the employer the right to terminate the employment contract during the probation period without warning and without gratuity, and you are entitled to only your wages for the basic working hours and overtime

Article (37):

The worker may be appointed under probation for a period not exceeding six months and the employer may dispense with the services of the worker during this period without warning and without end of service reward. The worker may not be appointed. Under experience more than once with one employer, and if the worker successfully passed the period of the experiment and continued to work, the period of service shall be calculated.
