Does the unit pay social security when the contract expires?

Legal analysis: there are two ways to deal with the expiration of the contract: endowment insurance, medical insurance and provident fund:

1. Go to the new unit to continue. In the meantime, if there is no unit, the payment will continue according to the regulations of self-employed (non-freelancers). 2. After completing the relevant formalities, pay according to the self-employed.

Legal basis: Article 84 of People's Republic of China (PRC) Social Insurance Law states that if an employer fails to register for social insurance, the social insurance administrative department shall order it to make corrections within a time limit; if it fails to make corrections within the time limit, the employer shall be fined more than one time and less than three times the social insurance premium payable, and the directly responsible person in charge and other directly responsible personnel shall be fined more than 500 yuan and less than 3,000 yuan.
