Dear Customer,                                
Thanks for joining and trusting us, much appreciated!

We would like to inform you that if your inquiry relates to resignation from work after five years, here are the following information:
The UAE Labor Law stipulates that the worker shall pay compensation to the employer equivalent to one and a half months in case the worker terminates the work contract.
That is, you must pay a month and a half salary if you terminate the employment contract for a reason not related to the employer. We recommend that you negotiate with your employer to reduce the required amount.
Here is the text of the UAE Labor Law regarding your inquiry:
Article (116):
Where a contract is revoked by the worker for reasons other than those stipulated in Article (121), he shall be required to compensate the employer for any damage the latter sustains as a result, provided that the amount of compensation shall not exceed half a month wage for three months or for the remaining period of the contract, whichever is shorter, unless otherwise stipulated in the contract.

If you have another question, feel free to ask us and we will answer with pleasure.
I hope my answer was helpful, please let me know if you have any follow up questions. If you feel I've answered your question already, please rate my answer from top of the page. Your feedback helps to ensure only the best experts are available to help you.

Dear Customer,                                
welcome again 

We would like to inform you that the fine to be paid is in accordance with the salary you are currently receiving, and the termination of the contract of employment specified term requires the payment of the previous fine and there is no way to reduce that fine unless negotiated and approved by the employer.
Regarding end of service benefits, we refer to the following information:
The end-of-service is calculated on the basis of twenty-one days' pay for each of the first five years, and is calculated on the last basic salary after excluding all allowances.
The fact that the worker terminates the contract of employment after a period of five years does not prevent him from the right to receive the end-of-service bonus.
Here is the text of the UAE Labor Law regarding your inquiry:
Article 138
Where a worker under a definite term contract abandons his employment at his own initiative before the expiry of his contract period, he shall not be entitled to severance pay unless his continuous period of service exceeds five years.
Article 139

 A worker shall forfeit entitlement to his entire severance pay in any of the following two cases:

1. If he is dismissed from service for any of the reasons specified in Article 120 hereof or if he abandons his employment in order to avoid being dismissed in accordance with that Article.
2. If he abandons his employment of his own accord, otherwise than in either of the two cases specified in Article 121 hereof, without notice (in the case of indefinite term contracts) or before completing five years of continuous service (in case of definite term contracts).

Kind Regards,
