 It should be noted that after reviewing your inquiry and legal scrutiny we would like to provide thataccording to the Qatari Labor Law, the worker shall be entitled the gratuity of at least 3 weeks wages for each year of service, provided that the worker has worked for the employer for one year or more.

Article (54)

In addition to any sums to which the worker is entitled to upon the expiry of his service, the employer shall pay the end of service gratuity to the worker who has completed employment of one year or more. This gratuity shall be agreed upon by the two parties, provided that it is not less than a three-week wage for every year of employment. The worker shall be entitled to gratuity for the fractions of the year in proportion to the duration of employment.

The worker's service considered as connected if terminated in any circumstances other than cases that provided for in Article (61) of this Law and returned to service within two months from the date of it expiry.

The last basic salary for the worker shall be taken as a basis for calculating the gratuity
The employer can deduct from the gratuity all the amounts that owed to him by the worker
