Isn't it illegal to sign a labor contract and pay social security in a unit?

Legal analysis: Do social security and labor contract have to be one company? There are two situations.

The first situation is that as long as you work in a company, the company must sign labor contracts with employees to determine the labor-employment relationship, and the company must purchase social security. Such companies must sign a labor contract to purchase social security, and the other four insurances must also be handled together.

The second situation is that the labor contract relationship of the labor dispatch unit exists between the labor dispatch agency and the dispatched workers, and their social security and labor contracts are not in the same company.

So to sum up, the labor contract and social security payment are not a company, but can be in a company.

Old-age insurance, the full name of social basic old-age insurance, is a social insurance system established by the state and society in accordance with certain laws and regulations to solve the basic life of workers who reach the working age limit stipulated by the state and terminate their labor obligations or quit their jobs because of old age.

A labor contract refers to an agreement between a laborer and an employer to establish a labor relationship and clarify the rights and obligations of both parties. The conclusion and modification of labor contracts shall follow the principles of equality, voluntariness and unanimity through consultation, and shall not violate the provisions of laws and administrative regulations. After a labor contract is concluded in accordance with the law, it is legally binding, and the parties must fulfill their obligations under the labor contract.
