The end-of-service gratuity is one of the rights of the worker to the employer in the event of the termination of the work contract, and the Saudi legislator obliges the employer to pay it to the worker at the end of the work contract, whether the work contract is for a fixed-term or indefinite-term. For this reason, this service allows for the method of calculating the end-of-service gratuity, the due date for the gratuity, and how to calculate it according to the rules of the Saudi labor system.
