How to protect social security when changing jobs?

Because the social security paid before changing jobs can continue to be paid. After leaving the job, the original employer will stop paying social security and transfer the social security relationship of the workers according to law. At this time, if the laborer finds a new employer, the new employer will pay social security according to law.

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.
