Non-competition clause and its application in the UAE

Dear Sir,

I am an Indian residence in Dubai for the last 24 years. I worked in a company with an unlimited contract for the last 14 years (from 2004) and left 15th March 2018.

My first unlimited labour contract was made in 2004. After that, it has been updated in 26-9-2017.

In the meantime, it is between my employer and me whenever they revise my salary they make a contract of 5 to 6 pages with the company rules and do's & don'ts.

In that, they mentioned that as below:

"The employee shall not, without the prior written consent of the employer, at any time during the period of 24 Months from the date on which he ceases to be employed by the employer take up part or full-time employment in any business where the Employer operates, or have shown good intention of operating, which in any way could be construed as being of a competitive nature to that of the Employer' business."
