What about social security before changing jobs in the city?

After changing to work city, you can transfer social security to work city and continue to pay social security. 1. Social security includes pension, medical care, work injury, unemployment and maternity insurance. Second, social insurance is a kind of insurance required by the state. The state develops social insurance undertakings, establishes a social insurance system and sets up a social insurance fund, with the aim of enabling workers to get help and enjoy insurance benefits in old age, illness, work injury, unemployment and childbirth. China's "Labor Law" and "Social Insurance Law" clearly stipulate that it is the legal obligation of the employer to pay social insurance for workers, which is obviously compulsory by the state, and the employer shall not refuse to undertake this legal obligation under any excuse or reason.

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.
