Workplace terrorism impacts employee safety. Prioritizing security measures and improving evacuation knowledge enhances perceived safety at work, especially for those with post-traumatic stress reactions.
Area of Science:
- Occupational Health
- Psychology
- Security Studies
Background:
- Workplace terrorism is an extreme form of violence with significant impacts on employee health and functioning.
- Previous research indicates workplace violence increases perceived threat and decreases perceived safety.
- Understanding factors influencing perceived safety post-terrorism is crucial for organizational well-being.
Purpose of the Study:
- To investigate longitudinal associations between perceived safety at work and employee views on security and emergency preparedness after a terrorist attack.
- To explore how prioritization of security measures, knowledge of evacuation procedures, and extent of training relate to perceived safety over time.
Main Methods:
- A three-wave longitudinal study of 3065 ministerial employees exposed to a terrorist attack in Oslo, Norway (2011).
- Linear mixed-effects modeling was employed to analyze associations between perceived safety and perceptions of security measures and emergency preparedness.
- Secondary analyses examined the role of post-traumatic stress reactions and demographic factors.
Main Results:
- Higher perceived prioritization of security measures and better knowledge of evacuation procedures were significantly associated with increased perceived safety at work.
- These associations were consistent both between employees and within employees over time.
- Extent of escape and evacuation training showed no strong association with perceived safety; post-traumatic stress reactions were negatively associated with perceived safety.
Conclusions:
- Enhancing perceived safety at work following terrorism involves prioritizing security measures and ensuring clear communication regarding evacuation procedures.
- Addressing post-traumatic stress reactions is vital for improving overall perceived safety among affected employees.
- Targeted interventions may be needed for specific employee groups, such as women and more educated individuals, to maximize the effectiveness of safety measures.
