How can an employer sue a company if it doesn't buy social security during the internship?

Legal analysis: Social insurance is compulsory insurance for workers' life and medical security. Among them, among all the benefits enjoyed by employees, only social security is compulsory. There are three ways to defend rights: 1. First, negotiate with enterprises and ask them to pay social security for themselves. If the unit still does not pay, then the employee has the right to terminate the labor contract voluntarily. 2, and then complain to the labor inspection brigade. The labor inspection brigade will send people to the unit for investigation. If the situation meets, the unit will face corresponding punishment, and of course the social security funds owed to employees will also be made up. 3. Finally, apply for labor arbitration. The relevant departments will require the units involved to pay the social security of employees in accordance with the regulations and pay certain economic compensation.

Legal basis: Article 17 of People's Republic of China (PRC) Labor Contract Law shall contain the following clauses: (1) Name, domicile and legal representative or principal responsible person of the employing unit; (2) The name and address of the laborer and the number of the resident identity card or other valid identity documents; (3) The term of the labor contract; (4) Work content and work place; (five) working hours and rest and vacation; (6) Labor remuneration; (7) Social insurance; (eight) labor protection, working conditions and occupational hazard protection; (nine) other matters that should be included in the labor contract as stipulated by laws and regulations.
