What if the original unit owes social security for two years and fails to pay it?

Legal analysis: if the unit stops paying the old-age insurance, it can apply for arbitration to protect its rights and ask the unit to pay back the old-age insurance.

Legal basis: Article 86 of the Social Insurance Law of People's Republic of China (PRC), if the employer fails to pay the social insurance premium in full and on time, the social insurance premium collection agency shall order it to pay it within a time limit or make up for it, and if it still fails to pay it, an overdue fine of 5/10000 will be added daily from the date of default, and the relevant administrative department will impose a fine of more than 3 times the unpaid amount/kloc-0.
