Personnel employed in the protective services are routinely exposed to events and situations that can be described as stress inducing and traumatic. While the general stereotype is that these occupations are highly stressful, as a result of this repeated exposure, recent studies have shown that such personnel rate the organisational characteristics of their job as more stressful than operational exposure to traumatic incidents. The aim of this investigation was to apply a model of organisational health in an emergency services context, with a specific focus on the contribution of organisational factors to employee stress and well-being. Participants were 321 police, ambulance and firefighting personnel. Structural equation modelling analysis revealed that organisational climate had the strongest influence on employee job satisfaction, with both direct and mediated relationships through coping and daily work experiences. The fact that organisational processes have such a profound impact on employee well being highlights the importance of acknowledging the effect of organisational influences on protective services employees, particularly for the development and promotion of truly preventative mechanisms in dealing with critical incident and occupational stress.
