According to the UAE Labor Law, a worker cannot terminate a fixed-term contract before end of its term.
If the worker terminates a fixed-term contract before the end of its term, compensation must be paid to the employer which must not exceed one and a half months' salary.
Moreover, terminating a fixed-term contract before the end of its term is considered illegal, and the employer can impose a ban against the worker for a period of one year.
We recommend you to negotiate with your employer in order to obtain a no-objection clearance to move to another company, so that to avoid a ban.
The UAE Labor Law, in regards of your inquiry:
Article 116
Where a contract is revoked by the worker for reasons other than those specified 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.
