Good evening I want to ask how can complain about...

In accordance with the provisions of the Federal Labor Law stipulated that the worker who completed a year or more in continuous service deserves an end-of-service gratuity at the end of his service and is calculated on the basis of twenty-one days' wages for each of the four years of service spent with the employer and in addition to that so  the employer bears the costs of your return to the agency that brought you from it or to any other place that has been agreed upon and if the employer violates this, you can file a complaint with the relevant labor office
