I have worked in the factory for more than ten years and didn't buy social security.

Legal analysis: workers can directly apply to the unit to pay social security, or directly propose to terminate labor relations. After the termination of labor relations, the unit will still pay social security. After the employee and the employer propose the labor relationship, the employer shall pay various social insurances for the employee. If the employer violates the law by failing to pay insurance, the employee may propose to terminate the labor relationship immediately on the grounds that the employer fails to pay social security.

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

Article 2 The state establishes social insurance systems such as basic old-age insurance, basic medical insurance, industrial injury insurance, unemployment insurance and maternity insurance, so as to guarantee citizens' right to receive material assistance from the state and society in accordance with the law in case of old age, illness, industrial injury, unemployment and maternity.

Article 3 The social insurance system adheres to the principles of wide coverage, basic protection, multi-level and sustainability, and the level of social insurance should be compatible with the level of economic and social development.

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.
