We would like to inform you that according to the UAE Labor Law for the disciplinary procedures before the termination are as below:
Article 102
The disciplinary measures that an employer or his representative may impose on the workers shall be as follows:
1. Warning.
2. Fine.
3. Suspension from work with reduced pay for a period not to exceed 10 days.
4. Denial or deferment of periodical allowance, in firms applying such a scheme.
5. Denial of promotion, in establishments applying a promotion scheme.
6. Dismissal without prejudice to severance pay.
7. Dismissal with denial of all or part of the severance pay. This penalty may not be imposed for reasons other than those exclusively specified in Article 120 hereof.
Article 103
The disciplinary regulation shall specify the circumstances in which each of the disciplinary penalties referred to in the preceding Article may be imposed. The Minister of Labour and Social Affairs may issue, by ministerial resolution, a model table of disciplinary actions and rewards, to be used by employers as a guide in preparing their own lists.
Moreover, you can ask for any deduct by the labor office by filing a complaint. We advise you not to resign and stay at work to prevent the employer to ask for any compensation as below article states:
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.
So if you want to terminate the contract then you will be forced to pay the visa expenses, then the sponsor will ban you and you will be forced to leave the country.
Article (120) of the Federal Labor Law:
The employer may dismiss a worker without notice if and only if the worker:
1. Assumes a false identity or nationality or submits forged certificates or documents.
2. Is engaged on probation and is dismissed during or at the end of the probationary period;
3. Commits a fault resulting in substantial material loss to the employer, provided that the latter notifies the labor department of the incident within 48 hours of his becoming aware of its occurrence;
4. Disobeys instructions on the safety of work or workplace, provided that such instructions are in writing and posted at a conspicuous place and are communicated verbally to the worker, in case he is illiterate;
5. Defaults on his basic duties under the contract and fails to redress such default Despite a written interrogation and a warning that he will be dismissed if such default is repeated;
6. Is finally convicted
7. Reveals any confidential information of his employer;
8. Is found in a state of drunkenness or under the influence of a narcotic drug during working hours;
9. Assaults the employer, the manager in charge or any of his workmates during working hours; or
