Is there only one person in the company who can pay social insurance? Those who meet the conditions for paying social security can. Because social security is guaranteed at the national legislative level, it is the right of employees to purchase social security. Article 2 of the Social Insurance Law of the People's Republic of China, the state establishes basic endowment insurance, basic medical insurance, work-related injury insurance, unemployment insurance, maternity insurance and other social insurance systems to protect citizens' rights to material assistance from the state and society in accordance with the law in cases of old age, disease, work-related injury, unemployment, maternity and other circumstances. Article 3 The social insurance system shall adhere to the principles of wide coverage, basic protection, multi-level and sustainable development, and the level of social insurance shall be commensurate with the level of economic and social development.
