Did not sign a labor contract, but paid social security.

Legal analysis: social insurance should be paid regardless of whether a contract is signed with the employer. Paying social security is an obligation clearly stipulated by law. Not signing a contract and paying insurance are actually two different things. You can still pay social security without signing a contract. According to the law, as long as labor relations exist, enterprises must fulfill all the obligations stipulated in the labor law. If employees do not actively perform, employees can complain to the labor inspection department.

Legal basis: People's Republic of China (PRC) Social Insurance Law.

Article 4 Employers and individuals who pay social insurance premiums according to law in People's Republic of China (PRC) have the right to inquire about payment records and personal rights and interests records, and ask 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.
