Without personnel files, the new unit has to pay insurance.

Personnel files are not directly related to social security, but indirectly related.

1. For new employees, after signing a labor contract with the company, the company can apply for social security only on the basis of the labor contract, and then the company will establish a new personnel file for the employees, and put the personnel data such as the labor contract and social security approval into the personnel file, which can be kept by the talent market file management bureau or the unit file department (provided that the company has the file management conditions);

2. For employees who have worked in other units before, if the new unit needs to check the personnel files when handling social security, and the Social Security Bureau needs to review the employees' previous working hours and social security contributions, it will handle the social security renewal times and link up the social security contributions.

3. Another function of the personnel case is that when the personnel department goes to social security to handle the formal retirement procedures of employees, the labor bureau should review the age and working years of employees and calculate the length of service. Length of service has a certain influence on retirement salary.

In short, personnel files must follow their own work units, or be stored in the local talent market archives management bureau, and its role cannot be ignored.
