In the current context of the pension scheme in Korea, low-income employees at small businesses have a higher risk of falling into a blind spot, not covered or benefiting from the social insurance, as they are reluctant to enroll due to the financial burden the pension contributions place on both employers and employees. The Korean society recognized the need to strengthen the social safety net for the vulnerable, particularly those at the lower end of the wage scale. In this regard, the National Pension Service (NPS) was committed to extending coverage to the difficult-to-cover groups in order to provide an essential foundation of retirement security for Koreans.

After continuously raising such issues in the National Assembly and the relevant agencies, in 2012, the NPS began to financially support those who earned below a certain income level and who worked for businesses with less than 10 employees. The amount of assistance was increased each year to extend coverage to a wider group of people, including the most vulnerable, in order to ensure a solid foundation of retirement security for Koreans.
