Problems with my salary with my boss

Referring to the Omani Labor Law that state that delaying any payment for more than extra seven days is illegal, and the ministry fines the violator.
The Omani Labor Law provides that the complaint should be filed within 15 days in case they want to revoke the termination, and within 1 year from the date of their right to such entitlements.

Article (51) of the Omani Labor Law relate that:

Wages shall be paid on a working day and at the workplace subject to the following provisions:

1-workers who are appointed on monthly wages shall be paid their wages at least once every month.

2-If the wage is paid on the basis of the number of pieces produced and the work requires a period of more than two weeks, the worker shall get a weekly payment on an account proportionate to the work he has completed and the balance of the wage shall be paid to him in full during the week following the completion of the work assigned to him.

3-In cases other than the above-stated, the salaries of the employees shall be paid weekly.

However, the salaries may be paid every two weeks or monthly if they agree in writing to such an arrangement and in all cases the salary must be paid within (7) seven days from the end of the period in which it becomes due.

A resolution by the Minister may set the timings for payment of employees’ salaries at the establishments under the provisions of this Law before their due date on the national and official occasions.
