I just want to ask if possible to resign at work...

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

We would like to inform you that according to the UAE labor law, the worker can not terminate the limited contract before the end of its term. In addition, if the worker terminates the contract before its end, he may be subject to a ban in addition to the payment of compensation equivalent to a month and a half salaries. If the employment contract is unlimited, it can be terminated provided that the worker informs the employer at least one month before the actual termination or as stipulated in the contract. The procedures for canceling the visa duration can not be determined , but the procedures to cancel the visa takes between five to fourteen days and may increase depending on the pressure of work at the concerned authorities.
Here is the text of the UAE Labor Law concerning 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. 
Article (117):
1. Either the employer or the worker may terminate an indefinite term contract for a valid reason at any time following its conclusion, by giving the other party a notice in writing at least 30 days prior to termination.
2. For the daily-paid workers, the notice period shall be as follows:
• One week: if the worker has been employed for more than six months but less than one year.

We would like to inform you that The UAE Labor Law stipulates that labor contracts are divided into two parts:

 First: Contract Duration:

Is a contract that has a start and end date and can't be terminated by any party before its end. If the worker terminates the fixed term contract before the end date without a legal reason, he must pay compensation to the employer not exceeding a maximum salary of one and a half months and If the employer terminates the fixed-term employment contract, compensation must be paid to the worker for a maximum period of three months

Second: The indefinite contract

A contract that has a date of beginning and end date, but any party may terminate it before the end of the date provided that the other party notified before the completion of a period of not less than thirty days and not more than ninety days and there must be a legitimate justification for the termination of this work contract is the text of the UAE Labor Law and we advise to negotiate with the employer in order to reduce the penalty requirement relating to resignation.
Finally, if a worker terminates a fixed-term or indefinite employment contract, it is possible for the employer to request a prohibition against the worker
Kind Regards,
