Can I sue the company for not paying social security in full?

Legal analysis: Yes, insufficient payment of social security is a violation of relevant labor laws. It is suggested to go to the company's social security labor arbitration to complain, demand full payment and provide relevant documents. After the company pays the overdue payment, the personal part shall be borne by the individual, and labor arbitration may impose administrative penalties on the company. In this case, the company will operate according to the payment. If you do not support arbitration, you can bring a lawsuit to the court. The contact labor contract can be carried out according to this, and the company has to pay compensation. The compensation depends on your salary. If negotiation fails, you can go directly to the local labor inspection department, file a labor dispute arbitration, fill in the labor dispute application form, and provide proof of the actual labor relationship between the company and you. If the labor department fails to negotiate with the company, it can directly sue the company's illegal behavior in the local people's court, and put forward the reasons and requirements for the complaint.
