1. If the company acts illegally, employees have the right to raise objections; If the company forcibly implements it, it can apply for labor arbitration; Article 80 of the Labor Contract Law of People's Republic of China (PRC) stipulates that if the rules and regulations of the employing unit that directly affect the vital interests of workers violate the provisions of laws and regulations, the labor administrative department shall order it to make corrections and give a warning; If it causes damage to workers, it shall be liable for compensation.

2. You and other employees of your company signed a customer service system with the company. According to what you said, it was "compulsory signing", but no one objected during the signing process and did not explain the employees' thoughts to the company in time, but subjectively thought it was "compulsory signing". Moreover, signing the customer service system has not caused serious damage to you, so it is legal.

I suggest that you and your colleagues can negotiate with the company to claim compensation first. If negotiation fails, you can apply for labor arbitration.
