I'm a salesman, but I'm not paid. Should the company buy me social security?

The relationship between salesman and employer is also a labor contract. Since the establishment of labor relations, the employer shall pay social insurance to the workers within 30 days. Refer to the Social Insurance Law

Article 58 An employing unit shall, within 30 days from the date of employment, apply to the social insurance agency for social insurance registration for its employees. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay.

Employees-free individual industrial and commercial households who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employing unit and other flexible employees shall apply to the social insurance agency for social insurance registration.

The state establishes a national unified personal social security number. Personal social security number is a citizen's identity number.
