Hi, If I plan on not availing my annual leave...

We would like to inform you that according to the UAE Labor Law, the employer is not allowed to do so as he has to pay leave allowance.
Article 78
Each worker shall be entitled to his basic wage and the housing allowance, if applicable, in respect of his days of annual leave. Where it was imperative for the work interest to put a worker on duty during all or part of his annual leave, and if the leave days on which he worked were not carried forward to the following year, the employer shall pay him his normal wage plus an allowance in lieu of leave, for the actually worked days, calculated on the basis of his basic wage.
In all cases, the worker may not be employed during his annual leave more than once during two consecutive years.
Article (79)
The worker is entitled for the salary of the annual leave which he did not receive if he has been terminated from the job, or he left the job after the notification period stipulated in the in the law. The indemnity shall be calculated on the bases of the wage of obtained during the leave.
Article (80)
