The UAE Labor Law stipulates that the employer is obligated to pay the end of service benefits upon the end of the work contract. The end of service benefits are calculated at the basis of twenty-one days ’salary for each year of service from the first five years, and thirty days’s salary for each year in excess of that.
It is calculated on the last basic wage after excluding all allowances.
If the employer refuses to pay the benefits, you can file a complaint at the Ministry of Human Resources and Emiratisation
We advise you not to sign any papers stating that you have received all your rights, so that the employer does not use those papers in the case.
