I left my job on September 6th, 2000. Will the social security company pay in September?

In this case, the social security company needs to pay.

According to the provisions of the Social Insurance Law of People's Republic of China (PRC), during the establishment of labor relations between employees and employers, employers shall pay social insurance premiums for employees. Even if employees leave their jobs in September 10, the social insurance premium in September will still be paid by the company because the labor relationship lasts until that month. In order to protect the rights and interests of employees and ensure that employees can enjoy the social security benefits they deserve before leaving their jobs.
