What are the penalties for not paying social security for workers in factories?

Legal analysis: if an enterprise fails to purchase social security for its employees, the social insurance administrative department should first order it to make corrections within a time limit; If no correction is made within the time limit, the employer shall be fined more than one time and less than three times the amount of social insurance premiums payable, and the directly responsible person in charge and other directly responsible personnel shall be fined more than 500 yuan and less than 3,000 yuan.

Legal basis: Article 3 of the Labor Law of People's Republic of China (PRC) stipulates that workers enjoy the rights of equal employment and occupation selection, remuneration, rest and vacation, occupational safety and health protection, vocational skills training, social insurance and welfare, submission of labor dispute settlement and other labor rights stipulated by law. Laborers should complete labor tasks, improve their professional skills, implement labor safety and health laws and regulations, and observe labor discipline and professional ethics.
