Hi, I would like file a complaint against my...

If your inquiry relates to your employer forcing you to give them your passport, here are the following information:
If your employer forces you to give you your passport without your consent, there is no legal provision that grants the employer the right to obtain the worker's passport without a legal reason.
If the employer has completed the procedures for obtaining the visa, health insurance and all other procedures, he may not retain the worker's passport without his consent and the worker can file a complaint with the police station and an additional complaint can be filed with the Ministry of Human Resources and Emiratisation.
If the employer is found guilty of retaining the worker's passport without his consent, a fine will be imposed against him

You must not sign the resignation, which the employer has to force you sign in exchange for returning the passport. If you sign this resignation, in that case, you might lose your rights. You shall adhere to file a complaint against the employer at the police and MOHRE .

The worker who wants to resign shall submit it to the employer, and the worker shall continue to work until a decision is made to accept or reject the resignation. Also, according to the UAE labor law, a definite employment contract may only be terminated by the end of its term. An indefinite employment contract may not be terminated until after the notice of the other party is given at least one month before the termination. Also, if the worker terminates the employment contract illegally, he shall pay a compensation to the employer, the amount of which does not exceed a month and a half salary as a maximum. Finally it should be noted that we could not determine whether returning to work without a request to withdraw the resignation letter is considered to be a complement to the employment contract or not, as this matter depends on the discretionary power of the labor court judge.
