1. It's no use calling the police. The easiest way is to complain to the local labor law enforcement supervision brigade by telephone. They will supervise and inspect the employing units according to the Labor Security Supervision Regulations and order them to pay the arrears of wages.
2. According to Article 30 of the Labor Contract Law, if the employer fails to pay the labor remuneration in full, the employee may apply to the local people's court for a payment order according to law, and the people's court shall issue a payment order according to law.
3. The most effective way is to apply for labor arbitration directly to the local labor administrative department (no charge, no lawyer) and claim compensation from the unit through the award issued by labor arbitration. If you don't pay compensation, you can apply to the court for enforcement.
4. While claiming wages through the above channels, you can also ask the unit to pay you compensation according to the standard of more than 50% 100% of the payable amount according to the provisions of Article 85 of the Labor Contract Law.
