hello sir / madam my company tell that they will...

if the work contract is limitedif the contract is terminated by the employer, then he is liable to compensate the worker for the loss he obtained as a result of the termination of the contract, provided that the amount of the compensation shall not exceed half a month wage for three months or for the remaining period of the contract, whichever is shorter, otherwise otherwise mandated in the contract.
in the unlimited contract Employer can terminate the contract after notifying the worker before a month not more than 3 months. If the employer did not complain with the notice then he must pay instead of the notice period and the compensation must be as the worker wage for that period full of part of it
you can file a complaint in any of Tasheel Offices that belong to the Ministry of Human Resources, In such situation the dispute may referred to the court and may grant the worker temporary work permit to new company till the judgment issued,

we would like to inform you that if the contract includes work under trial for a certain period, in this case the employer can terminate the employee's contract during the trial period, or at the end of that period without commitment to the notice period, and deprive the employee from the end of service benefits ranging from one to six months.
Meaning that the worker can work or not with the employer under trial, which mean that it is not mandatory and it is agreed by both parties.
