Majority of the police officer job satisfaction research in the field of Criminal Justice began with an examination of demographic factors. As the research progressed, job satisfaction research has expanded to work-related factors to predict job satisfaction. Although workrelated factors have benefited the job satisfaction research tremendously, further examination of job satisfaction is needed. Hence, the current study focuses on familial factors as a predictor of job satisfaction. Are officers with happier and more harmonious family have higher levels of job satisfaction? To answer this, we examine Korean Coast Guard police officers and their job satisfaction levels. In brief, the results indicate that work-related factors such as work condition, work unsafety, organizational cohesion, and work pride were significant predictors of job satisfaction. Most importantly, the familial factors such as the amount of family conversation, general relationship with family members, and family-work conflict were significant predictors of job satisfaction.
