ABSTRACT
The four case studies that make up Part IV demonstrate what can be achieved when working in organisational settings. The first two were designed to try to identify the impact of two types of traumatic experience on workers. In the first, the employees were crew members working in cash carrying vans. All had been exposed to an armed raid. The results of the study showed that there were personal and situational factors which appeared to make the incidence of posttraumatic stress more likely. These included a history of anxiety or depression and being a parent. There were also some situational factors which were associated with higher levels of post-traumatic stress. These were where a gun was fired, or they were threatened with gas or a physical attack. This study supports much of the previous work in this area and suggests that where any of these factors are present the organisation should take special care of the employee.
