is it true that there is no probation period if I am directly hired by an agency?

Yes, if it is available in the contract.

Yes, as long as the employment contract stipulates that.

Dear J.,

As per domestic workers' law in the UAE, there is a probation period that is not more than 6 months, irrespective if one is 'directly hired' or not.

Refer to your contract with the agency as it is stated in the law that the employment contract shall clearly indicate the probation period.

Regards.
