Eighteenth labor administrative departments at all levels have the right to supervise the payment of wages by employers. If an employing unit commits one of the following acts that infringe upon the legitimate rights and interests of workers, the labor administrative department shall order it to pay wages and economic compensation to the workers, and may order it to pay compensation:

(1) Deducting or delaying the wages of workers without reason;

(2) refusing to pay overtime wages to laborers;

(3) paying workers' wages below the local minimum wage standard.

The standards of economic compensation and compensation shall be implemented in accordance with the relevant provisions of the state.

Article 19 In case of a labor dispute between a laborer and an employer due to the payment of wages, the parties concerned may apply to a labor dispute arbitration institution for arbitration according to law. Anyone who refuses to accept the arbitration award may bring a lawsuit to the people's court.
