Where can the factory complain if it doesn't sign the payroll?

Legal subjectivity:

1. You can complain to the labor inspection department where the company is located. The labor inspection department is generally located in the local Ministry of Human Resources and Social Security Bureau, and its internal organs require the labor inspection department to investigate, coordinate and punish according to its functions and powers. 2. If the complaint is invalid, you can file a labor arbitration with the labor and personnel dispute arbitration committee where the company is located, and ask the company to pay relevant wages and economic compensation. Generally, a ruling will be made within 45 working days. If it's final, you can do it even if the company doesn't perform it.

Legal objectivity:

Article 83 of the Labor Law If a party to a labor dispute refuses to accept the arbitration award, he may bring a lawsuit to the people's court within 15 days from the date of receiving the arbitration award. If one party neither brings a lawsuit nor performs the arbitration award within the statutory time limit, the other party may apply to the people's court for compulsory execution.
