Data collection for effect and process evaluation. The data for process evaluation will be collected via (a) observation and audio recordings made during all main intervention activities, (b) questionnaires distributed to all team leaders, (c) various organizational documents such as evaluation forms from activities and meeting minutes collected during the course of intervention, and (d) interviews conducted at different levels of organization (example. health and safety representatives, human resources personnel, steering group members, and line managers and workers from both the intervention and control group). For collecting information for both effect and process evaluation, a main questionnaire at T0, T1 and T2 will be used.
