The current employer delays the salaries. How to leave and join a new employer?

Hello ma'am,

I am working in a private company in Dubai. My contract is unlimited and my service is 4years 10 months. My employer doesn’t pay salary regularly. There is always a delay.

If I ask them, they pay only partial money in cash and the balance amount will adjust in the next payment. This process was started during Covid from Jan 2020 and till today they are continuing the same.

Because of such process, my salary got accumulated and it is outstanding. When I check with the employer to clear my dues, they give false promises that they will settle in a week's time.

I decided to put resignation and get a new job offer. The employer wants 30 days' notice but the new company said they will not wait for 30 days and need me to join within 15 days.

Kindly advise as I don’t want to lose my new job offer and, at the same time, my pending salaries and settlement.

Thanks!
