When recruiting employees, the company should first extract and review the files, and then sign the labor contract, and the files should be kept by the company; Irregular employee files are ignored at all.

To apply for social insurance, you only need to submit a copy of the employee's ID card and labor contract, and you don't need to provide the employee's personnel file.
Jiangsu implements the employment permit system, while Shanghai implements the labor manual system, and local policies will be different. I suggest you call the local social security telephone number "12333" for consultation, which is more in line with the actual situation.
