This study explored health outcomes following workplace aggression among social workers in Israel. Grounded in the social exchange theory, a relationship-based perspective was used to explain the mechanism through which exposure to workplace aggression results in employee outcomes. Reports of employees and managers were analysed with respect to the impact of varied forms of aggressive behaviours perpetrated by clients and co-workers on posttraumatic stress and somatic symptoms. The intervening effects on symptoms of two forms of perceived organisational support, organisational procedural support and interpersonal co-worker support operationalised as team trust were examined. Overall, 548 employees and 89 managers in 31 social services departments completed self-report questionnaires. Results revealed positive associations between exposure to both co-worker and client aggression, and posttraumatic stress and somatic symptoms. Importantly, while perceived organisational support is often equated with social support, this study found that two elements, organisational procedural support and team trust, had differing impacts on somatic and posttraumatic stress symptoms following WPA. Specifically, team trust was negatively associated with symptoms, while organisational procedural support showed no effect. This study has important implications for timely prevention measures to deal with workplace aggressions and valuable directions for future studies.
