Labour law claims are time barred after one year

I have worked for a company in a senior management role for two years and resigned due to my personal reasons.

My resignation was accepted and I was asked to hand over the charge to new management since more than one year ago now. My visa was also cancelled after a few months of my resignation.

The new management took the charge and could not manage the business efficiently after my exit, and the business which resulted in the termination of the new management.

The company is now blaming me that during my tenure with the company earlier, there was some wrong decision taken which has caused losses to the company.

The company now wants to file a legal case against me. I am getting several threatening messages and calls to come back and resolve the old issues, which is causing me mental torture and disturbance in my family.

I am not in a position to help the company to recover their irreparable damages now.

Please advise what is the UAE labour law for such a situation.
