Social security doesn't match the resignation certificate.

Legal analysis: There are many reasons why the resignation certificate is inconsistent with the social security record. The inconsistency between the resignation certificate and the social security record does not mean that the employee lied about the departure time. If the employee's resignation time is consistent with the social security record, and the employee has other evidence to prove that the employee's actual resignation time is the time corresponding to the social security record, then the employer cannot refuse to hire the employee.

Legal basis: Article 4 of People's Republic of China (PRC) Social Insurance Law. Employers and individuals in People's Republic of China (PRC) pay social insurance premiums according to law, and have the right to inquire about payment records and personal rights records, and require social insurance agencies to provide social insurance consultation and other related services. Individuals enjoy social insurance benefits according to law and have the right to supervise the payment of their own units.
