What should I do if the sales department doesn’t pay commission to the intermediary?

Legal analysis: If no commission is given, it depends on whether there is a deposit receipt. If there is the word "deposit", the sales department can ask for a double return of the deposit if you breach the contract. If you breach the contract, the deposit will not be refunded. This is the "deposit penalty" stipulated by law. You can entrust a lawyer to intervene in civil litigation procedures. Legal basis: Article 18 of the "Interim Provisions on Wage Payment" provides that labor administrative departments at all levels have the right to supervise the employer's wage payment. If an employer commits 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 workers, and may also order it to pay compensation: (1) Withholding or delaying wages from workers without reason; (2) Refusing to pay wages to workers; Failure to pay workers wages for extended working hours; (3) Paying workers wages lower than the local minimum wage standard. The standards of economic compensation and compensation shall be implemented in accordance with relevant national regulations.
