Can I ask the company to pay social security when I leave during the probation period?

Yes Employees should also be insured during the probation period. The probation period is an investigation period of no more than six months agreed by the employer and the employee for mutual understanding and choice after establishing labor relations. Once the labor relationship is established, the employer shall pay social insurance for the workers according to law, and the probation period is not a "special period" independent of the labor relationship. Article 58 of the Social Insurance Law, the employing unit shall, within 30 days from the date of employment, apply to the social insurance agency for social insurance registration for 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.
