Hii sir

Please note that my answer to your question will be purely from an academic point of view based on the limited initial information provided.

Therefore, it should not be treated as a legal opinion of the need for adequate knowledge and review of relevant documents when reading the applicable laws.

So if you meant the "Probation Period" in the UAE
 In general this period can last between 3-6 months.
But as per UAE Labour Law, probation period is for 6 months.
Please note that the probation period is the period of time where your employer scrutinises you on the job performance and can legally terminate you during this period with a 1 day notice.
