Is it illegal for retirees to pay social security for re-employment?

Legal analysis: It is not illegal for retired workers to pay social security for re-employment. As a retired employee, his work unit has not terminated the labor contract, and his social security benefits should be borne by the original work unit according to law. However, the social security benefits undertaken by your original unit and paid by your new unit will cause double payment, which has no practical significance to yourself.

Legal basis: Article 73 of the Labor Law of People's Republic of China (PRC). Workers shall enjoy social insurance benefits according to law under the following circumstances: (1) Retirement; (2) Being sick or injured; (3) Being disabled at work or suffering from occupational diseases; (4) unemployment; (5) bearing. After the death of an employee, his survivors shall enjoy the survivors' allowance according to law. The conditions and standards for workers to enjoy social insurance benefits shall be stipulated by laws and regulations. Social insurance premiums enjoyed by workers must be paid in full and on time.
