This study examines factors associated with Israeli social workers' investment of effort in, and inclusion of, volunteers in their work. The variables are drawn from three theories: status characteristic theory, psychological contract theory, and organizational culture theory, and from claims regarding training in working with volunteers. The sample consisted of 118 randomly selected direct social workers in 26 municipal social service departments in Israel. The instruments were designed specifically for the study.Findings: Social workers' effort investment and inclusion increased when they: (a) viewed volunteers as contributing to social workers and the organization; (b) expected themselves to invest effort in their volunteers; (c) believed their volunteer met their expectations with regard to service users and social workers; (d) trusted their volunteer; (e) perceived their managerial culture, peer culture, and artifacts as encouraging effort investment and inclusion; and (f) received training in working with volunteers. Implications: On a theoretical level, the findings expand our knowledge about factors that may impact on social workers' investment of effort in volunteers and their inclusion. On a methodological level, instruments with good psychometric properties were developed to examine the associations studied and these can serve in future research. On the practical level, the findings highlight the importance of training in working with volunteers and underscore the value for managers and volunteer coordinators discussing the workers' psychological contract with them and of fostering an organizational culture that encourages effort investment in, and inclusion of, volunteers.
