If the company's practices are illegal, it may apply to the labor arbitration committee where the company is located for labor arbitration. Demand payment of wages and economic compensation. The company may terminate the labor contract with you on the grounds that you have seriously violated labor discipline and company rules and regulations, but it must investigate and verify, make a decision according to the prescribed procedures and notify you. It is illegal for the company to terminate the labor contract with you on this ground if you don't "lower the quality for no reason" at all. Even if you seriously violate labor discipline and company rules and regulations and damage the products, the company can terminate the contract with you and demand compensation for the losses, but it should not be "unpaid wages". When applying for arbitration, you only need to provide proof of the existence of a labor contract relationship with the company. Other evidence about your punishment basis, the basis for terminating the contract, salary standard, etc. shall be provided by the employer and proved to be legal. If the company cannot provide it, it should be considered that the company's behavior is illegal.
Satisfied, please adopt.
