Despite today’s considerable changes in the labor market, studies on the career commitment of social workers remain scarce. The current study focuses on the personal, organizational, and vocational factors of social workers’ career commitment. The study included 251 social workers from various organizations in Israel. Findings show that their career commitment is positively correlated with Protean and Boundaryless career patterns, as well as with their perceived career success. These findings could contribute in developing tools that could increase social workers’ career commitment, which in turn would enable them to be more effective at work, to the benefit of their clients.
