Choose your country, add your name and employer, and get a resignation letter that states the notice period your country's labour law sets. Copy it or download it, then give your employer a signed copy.
Before you send it, read the resignation rules for all six countries to see what resigning does to your end of service pay.
UAE: the period in your contract, between 30 and 90 days. Saudi Arabia: 30 days. Kuwait: 3 months if you are paid monthly, 1 month if not. Qatar: 1 month in your first two years, 2 months after that. Oman: 30 days if paid monthly, 15 days if not, or longer if your contract says so. Bahrain: 30 days. In Kuwait, Saudi Arabia, Oman and Bahrain these are the rules for open-ended contracts, so check your own contract too.
Put it in writing in every country. The UAE, Saudi Arabia, Qatar, Oman and Bahrain laws ask for written notice, and in Kuwait a written copy is your proof. Keep a copy that your employer has signed, or proof that you sent it. In Bahrain the law says to hand it over against a signature or send it by registered post.
In Saudi Arabia, a resignation is treated as accepted if your employer does not answer within 30 days, and the employer can postpone acceptance for up to 60 days in writing. You can withdraw within 7 days of submitting it. In the other five countries, the notice articles do not add an approval step for the employer, so what matters is that you give notice in writing and work through the period.
It depends on the country. In Saudi Arabia you get nothing under 2 years, one third from 2 to 5 years, two thirds over 5 to under 10 years, and the full amount from 10 years. In Kuwait you get nothing under 3 years, half from 3 to under 5, two thirds from 5 to under 10, and the full amount from 10. The UAE, Qatar, Oman and Bahrain texts have no resignation cut. Use the country guide for the figures.
