The authors investigated the impact of organizational justice on social workers' intention to leave Korean social service agencies. Specifically, this study concentrated on the moderating effect of organizational justice on the relationship between burnout and intention to leave. The authors surveyed 218 front-line social workers from 51 social welfare service centers in Korea. Data were collected from a sample of social workers indentified through a multistage cluster sampling process. The authors used a linear mixed model to analyze the multilevel data structure. This study had three major findings. First, higher levels of burnout of individual social workers corresponded to increased intention to leave. Second, higher levels of organizational justice of social welfare service centers corresponded to decreased intention to leave. Finally, and most important, the organizational justice of social welfare service centers moderated the impact of burnout on individual social workers' intention to leave. On the basis of these results, the authors discuss the importance of organizational justice to social service agencies.
