The law regulating labor relations gave the employer the right to require the worker not to compete or participating in a competing work or projects within a specified period of time and place

Therefore, if your employer requires you not to compete for one year or more after the end of the contract, you are necessarily bound to fulfill this obligation. You can get rid of this obligation by filing a lawsuit in the labor court and asking them to exempt from this condition. If your employer does not require this, you are entitled to work in a competitive company without any legal problem.

Article 127:

Where the work assigned to a worker allows him to become acquainted with the employer's clients or to have access to his business secrets, the employer may require him to undertake not to compete with him or participate in any enterprise competing with his own, after the termination of his contract. For such an undertaking to be valid, the worker must be at least 21 Gregorian years of age at the time the agreement is concluded, and the agreement must be confined, in terms of time, place and the nature of the business, to the extent necessary to safeguard the employer's legitimate interests.
