In Shanghai, the company's policy of supplementing social security for employees is generally to supplement 1~3 months on the human resources computer. If the supplement is unsuccessful, you can go directly to the counter and go to the social security center where the employee works to handle related business. If it takes 3~6 months to make up for it, the process is complicated, and you can also go to the counter to help with it under the guidance of the local social security teacher.

If it is overdue for more than a few months, it can be handled in theory, but the company needs to submit relevant work materials, which involves some illegal matters of the enterprise and is difficult to operate. The limitation of employee labor arbitration and social security related matters is one year, and the general arbitration results can be paid back for two years when paying social security. That is, if you know that your social security rights and interests have been hurt, you can file a labor lawsuit within one year, and you can only repay it for two years at most.
