In the event that your employer harassed you and subjected you to mental disturbances, in this case you can file a complaint against your sponsor in the relevant labor department and accuse your sponsor of exposing you to mental disturbances and the employer will be called in to prevent him from that and if he refuses to stop your harassment, you can file a claim with the request to terminate the work contract and cancel the work visa with your sponsor
Article (105):
A worker may terminate the contract of employment without notice in any of the following events:
1. Assault by the employer or his representative against the worker, during or because of the work, by words or deeds that are punishable by law.
2. An act committed by the employer or his representative that is considered as immoral against the worker or a member of his family.
Termination of the contract in either of the above two events shall be deemed as unfair dismissal by the employer.
