The unit has no social security.

Legal analysis: For workers, if the employer does not pay social security, it will actually harm their legitimate rights and interests. However, some people think that they agreed with the unit from the beginning not to pay social security, which certainly has no impact on themselves. But in fact, according to the laws of our country, employers must buy social security for their employees.

Legal basis: Article 84 of People's Republic of China (PRC) Social Insurance Law states that if an employer fails to register for social insurance, the social insurance administrative department shall order it to make corrections within a time limit; if it fails to make corrections within the time limit, the employer shall be fined more than one time and less than three times the social insurance premium 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.
