I just want to ask my contract of employment copy

We would like to inform you that according to the UAE Labor Law, which regulates the contractual relationship between the employer and the worker, states that both parties shall have a copy of the contract as below article states:
Article (35):
Subject to the provisions of Article 2, an employment contract shall be written in duplicate, with one copy to be delivered to the worker and the other to the employer. In the absence of written contract, adequate proof of its terms may be established by all admissible means of evidence.
If the employer refused, then you can go to the labor office and file a complaint to force the employer to grant you a copy of the contract.
