Dear kamel, If I am not wrong you are referring to your gratuity which will be awarded at your end of service. It is paid according to your basic pay, which is as stated, 2000 QR. Up on completion of 1 year service, you will be granted 21 days of your basic pay as gratuity (i.e. 2000/30= 66.6; 66.6x21=1399 is your one year gratuity).
Ignore the message if you are not referring to gratuity. Thanks and have a good day.
