The moderating effect of exposure to robbery on the relationship between post-traumatic stress and job satisfaction

Research has disregarded the boundary conditions of the effects of post-traumatic stress symptoms (PTSS) at work. Addressing this issue, the present study examines the moderating impact of the (shared vs. isolated) exposure to robbery on the relationship between PTSS and employee job satisfaction. Drawing on the conservation of resources theory, we argue that PTSS would positively affect employee job satisfaction when the robbery is experienced collectively. To test our predic-tions, we conducted a two-wave study—with a lag of two months between measurements—on 140 employees from a national bank in Italy. Results from hierarchical regression analyses supported our prediction: the exposure to robbery moderated the relationship between PTSS and job satisfac-tion. While within the “isolated exposure” group the job satisfaction score was higher among less symptomatic victims, within the “shared exposure” group those with high PTSS reported higher job satisfaction levels than those with low PTSS. We discuss the implications of these findings for theory and practice.
