Must the company issue a social security certificate when leaving the company?

The resignation certificate is actually a document that the new company requires to avoid disputes because it is worried that you still have a labor relationship with the original unit. It has nothing to do with insurance or not. If the new company doesn't want it, you don't have to provide it. However, if you want to transfer the original social security to the new unit, you must go to the original unit to handle the transfer fee, and the resignation certificate is also needed; Personally, I think it is normal to leave and change jobs, but the relationship with the original unit should be improved and the new unit should be coordinated. One-month handover period, it is recommended to run on both sides.

Legal objectivity:

Article 50 of the Labor Contract Law: The employing unit shall issue a certificate of dissolution or termination of the labor contract at the time of dissolution or termination, and go through the formalities of transferring the relationship between files and social insurance for the employee within 15 days. Laborers shall handle the work handover according to the agreement of both parties. If the employing unit should pay economic compensation to the workers in accordance with the relevant provisions of this law, it should pay it when the work handover is completed. The employing unit shall keep the text of the dissolved or terminated labor contract for at least two years for future reference.
