The company buys social security for non-company employees, and the boss asks to sign an agreement. If something goes wrong, it has nothing to do with our company. Please help, thank you.

Because the government's social insurance management regulations stipulate that only company employees can handle the company's social security relationship, and non-company employees can handle the company's social security relationship. One is violation of regulations, and the other is unclear economic responsibility. In the social security relationship paid by the company, the social security premium paid is a part of the company, and the two parts are merged into one person's social security account, not the company employee, but the company also has to pay the social security premium for her. How does the company spend this money and how does it enter the account? Therefore, this is illegal.
