How to appeal a case after losing it while its first appeal is rejected?

My employee has filed a case against me. I lost the case.

The employee is claiming AED 54,000/- from the court. Dubai court has given a decision against me. In the "Petition for review - labor" section, I filed for an appeal which I lost again.

I need to appeal again in order to file a case as he has forged my signature and his salary was AED 2700/- and all salaries are paid while he is claiming that AED 50,000/= was paid by him as company expenses.
