Good evening

What the employer has done is considered against the law and therefore, with no evidence at the employer and the termination of services, it is considered an arbitrary chapter that requires the employer to pay compensation to the worker in accordance with the text of Article (115)
Article 115
Where an employment contract is for a definite term and the employer revokes it for reasons other than those specified in Article (120) he shall be required to compensate the worker for any damage the latter sustains, provided that the amount of compensation shall in no case exceed the aggregate wage due for a period of three months or the remaining period of the contract, whichever is shorter, unless otherwise stipulated in the contract.
** The Labor Office may also give you permission to change the workplace without the need to not object to the sponsor if it proves that the employer is abusive in completing the work and what is not achieved with legal articles, especially Article (120) of the Labor Law, so we recommend that you pursue the complaint before the Labor Office
*** So you can go to the work office and file a complaint and claim all labor rights
Article (90)
Without prejudice to the cases in which the employer is entitled to dismiss the worker without warning or the remuneration provided for in this law, the employer shall not be entitled to dismiss the worker without notice. The worker shall be dismissed or warned of dismissal while enjoying his leave provided for in this dismissal.
Therefore, you can go to the labor office and file a complaint and explain the details and they will cancel the visa if the employer was arbitrary.
