It is against the labor law to reduce wages without reason. If the company really needs to reduce its salary due to poor management, it needs to reach an agreement with the employees through consultation, and it should be in written form. According to Article 35 of the Labor Contract Law, the employer and the employee can change the content of the labor contract through consultation. Changes to the labor contract shall be made in written form. If the salary is reduced without reason, the employee may propose to terminate the labor contract in writing on the grounds of "not paying the labor remuneration in full and on time", and ask the employer to pay the corresponding economic compensation according to the working years. If the employer refuses to pay, the employee may apply to the Labor Bureau for labor arbitration.
