Hi sir I was complete 12 years in Oman company...

If your inquiry relates to the employer's refusal to pay your dues, here is the following information:
At the end of the work contract, you can ask the employer to pay the following dues:
1- End of service indemnity is at the rate of 15 days’ wages for each year of service for the first 3 years and one month’s wages for each of the following years.
2- Leaves you did not get.
If the employer refuses to pay your dues, you can file a complaint with the Ministry of Labor, provided that you ask to be allowed not to travel until a decision is issued in the labor complaint.
