The effect of a health and safety climate intervention on worker health and safety.

H1: Compared to a control group of teams, employees in teams who are subject to the safety climate intervention will report higher levels of safety climate, -knowledge and -motivation measured at post-intervention (T1).



H2: Compared to a control group of teams, teams who are subject to the H&S climate intervention will report lower levels of physical and mental health problems, and H&S behavior measured at the first follow-up (T2)



H3: Compared to a control group of teams, teams who are subject to the safety climate intervention will report lower levels of work-related absenteeism and work-related health care utilization measured at the second follow-up (T3).



H4: The positive effect of participation in a safety climate intervention on H&S performance will be mediated by changes in safety climate, behavior and health problems.

T0 = pre intervention (1-3 weeks before start intervention)

T1 = post intervention (3-5 months after start intervention)

T2 = follow-up 1 (6 months after post intervention)

T3 = follow-up 2 (12 months after post intervention

The goal of the intervention is to improve the health and safety climate perceptions of teams involved in the intervention. The design of the intervention will include three small-scale interventions aimed at improving at least three health and safety climate dimensions (top management priority, direct management commitment, group norms).

1. Executive management WalkAround

2. Safety-specific Transformational Leadership coaching of direct supervisors

3. Teams engage in an online discussion of healthy group norms and -behavior using the online tool 'Synmind'
