I need to ask about temporary contracts

We would like to inform you that according to the UAE Labor Law, if your contract is limited and you filed resignation then the employer may ban you by filing absconding report against you in the labor office. So we advise you to complete the contract 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.
