The aim of this study is to examine how labor transition of homeless women is proceeded, and to identify mechanisms that cause them to be excluded from labor market. For this, five homeless women who have lived in shelters, and have had labor experience in the market were sampled and analyzed using generic qualitative research methods after in-depth interview. As a result of analysis, homeless women entered the labor market with the aim of self-reliance. But homeless women with poor human capital have been unemployed and employed repeatedly in an secondary labor market. Especially, the psychological and mental impairment of the female homeless had a negative effect on their performance and relationship with their colleagues, thus causing them to be excluded from jobs. So homeless women were subjected to transit downward to work-poor labor market. Due to low wages and unstable labor in the poor labor market, homeless women couldn't escape from poverty. In order to escape from homelessness, most of all, active labor support services are required. and continuous counseling, case management and linkage of mental health services are suggested. Finally, it is suggested that the expansion of support facilities, expansion of residence period, and stable housing support services are necessary.
