Switching jobs

HI ALL

I just have a question that if any person who has completed his first visa job (2 years) in UAE and has renewed the job contract for second visa i.e another 2 years, in case if between he leaves the job will there be any ban imposed on him?  Like briefly after completion of first visa is there any ban (for limited time contract)

Hope you would have understood my concern.

Syed
