Social enterprise is an organizational form reflecting a nation’s social responsibility and value of life. In Korea, social enterprise promotion act was enforced from year 2009 and many social enterprises were started for last 9 years. However, the failure rate of social enterprises is increasing continuously and the status of Korean social enterprise is still staying at an immature stage.

The company has been made success using linked employment system for the disabled. The act on employment promotion for the disabled requires that mid and above sized companies to employ a certain rate of the disabled.
