My old company wants to put absconding ban to me...

If your inquiry relates to a ban being imposed against you, here is the following information:
At the end of the work contract, the employer must review the General Administration of Residence to apply to cancel the worker’s visa, and within thirty days from the date of visa cancellation, the worker can either obtain a new work contract or leave the UAE to avoid paying a fine due to overstaying and if the previous employer filed an escape report against you because you submitted a complaint to the Labor Office, in that case, you can file a new complaint indicating the maliciousness of the escape report and that the employer has made an escape report because you submitted a labor complaint, provided that you provide evidence that proves the validity of your complaint.
