We would like to inform you that according to the UAE Labor Law, end of services is the worker right and he can claim for it once his job is done. If the employer didn't provide it then you can file a complaint in the labor office as below articles state:
Article (132):
A worker who has completed one or more years of continuous service shall be entitled to severance pay at the end of his employment. The days of absence from work without pay shall not be included in calculating the period of service. The severance pay shall be calculated as follows: 1. 21 days' wage for each of the first five years of service. 2. 30 days’ wage for each additional year of service provided always that the aggregate amount of severance pay should not exceed two year's wage.
Article (133):
A worker shall be entitled to severance pay for any fraction of a year he actually served, provided that he has completed one year of continuous service.
Article (134):
Without prejudice to the provisions of laws that grant pensions or retirement benefits to employees in certain firms, severance pay shall be calculated on the basis of the wage last due for monthly, weekly and daily paid workers, and on the basis of the average daily wage referred to in Article 57 hereof for those paid on piecemeal. The wage used as a basis for calculating severance pay shall not include whatever is given to the worker in kind, housing allowance, transport allowance, travel allowance, overtime pay, representation allowance, cashier’s allowances, children education allowance, allowances for recreational and social facilities, and any other bonuses or allowances.
Article 123
1. Where a worker is arbitrarily dismissed, the competent court may order the employer to pay him a compensation, to be assessed by the court with due regard to the nature of the work, the extent of damage sustained by the worker and his period of service, and after investigating the work circumstances, provided that such compensation shall in no case exceed the worker's wage for three months, calculated on the basis of his last wage.
2. The provisions of the preceding paragraph shall not prejudice the worker's right to the gratuity he is entitled to and the compensation in lieu of notice provided for in this law.
Article (75):
A worker shall, for each year of service, be entitled to an annual leave of not less than:
1. Two days a month, where the worker’s period of service is more than six months but less than one year.
2. 30 days a year, where the worker’s period of service is more than one year.
Where a worker's service is terminated, he shall be entitled to annual leave in respect of fractions of the last year.
Therefore, it is possible to file a complaint at the labor office and claim through this authority. If it is not possible for this authority to help you, it is possible to resort to the court and obtain a court ruling against the employer and compel him to pay you.
