Plain English Summary

Background and study aims
Studies have shown that need for recovery (a person’s desire to be temporarily relieved from work stressors to replenish his or her resources) is related to work demands and resources among workers. In the short term, high work demands lead to an increased shortage of resources which is considered to enhance the need for recovery. In the long term, absence of recovery may lead to tiredness, exhaustion, loss of function and physical and mental problems. The accumulated tiredness from repeated insufficient recovery is associated with health problems, sick leave and work disability. Work ability is also associated with long term effects of insufficient need for recovery,
i.e., tiredness, reduced productivity, stress and burnout as well as future sickness absence and early retirement. Blue collar workers (people who perform manual labor) generally experience higher need for recovery, tiredness, reduced work ability and comparatively higher risk of early exit from the labor market. Thus, it is important to develop effective initiatives to reduce need for recovery and increase work ability among these workers to improve the balance between work demands and resources. However, research about these methods is scarce. Therefore, the present study aims to find out how well our method to improve the balance between demands and resources among industrial workers works.

Who can participate?
Workers from work teams belonging to selected departments mainly involved in manufacturing in industrial companies in Denmark will be offered participation in the study.

What does the study involve?
The study involves an audit to find out the existing resources in the companies. Various workshops will be conducted to train leaders and health and safety representatives for supporting and facilitating the study method. The working teams and later the individual workers will participate in sessions to discuss current work demands and resources (both physical and psychosocial), develop action plans and implement them to minimize demands and maximize the positive effects of the resources at work. The workers will be involved in collecting information for a broad effect and process evaluation. For these evaluations, information will be collected via questionnaire at the start, at the end of first year and at the end of second year and also via text messages each month. The information will also be collected via interviews at different levels of organization, via observations during the activities and via organizational records and documents.

What are the possible benefits and risks of participating?
This activities will benefit the workers by improving their work resources and demands,
potentially reducing need for recovery and improving work ability. This will also provide the team leaders with a systematic method to deal with work environment problems and improve the balance between demands and resources in the work team. This will benefit the participating organizations by providing them with the knowledge and training for performing these initiatives in the future. There are no known risks of participating in this study.

Where is the study run from?
The study is managed by a research group from The National Research Centre for the Working Environment in Copenhagen, Denmark.

When is the study starting and how long is it expected to run for?
This is a two-year study. The contact with work places and planning of the study method started in January 2013. In one of the companies, the organizational resources audit has started in May 2013 and the initial information collection will begin in June 2013. An identical procedure will be performed after approximately six months in a second company.

Who is funding the study?
This study is a part of a research grant from the Government (Satspulje grant), Denmark.

Condition

All workers with or without diseases and working in the participating teams in the industrial sectors.

Intervention

This is a two-year waitlist randomized control study.
In the first year, the intervention group will receive the treatment while control group will receive ’treatment as usual’. The intervention will be conducted at different levels of organization. At the organizational level, an audit of organizational resources will be carried out to map the existing resources in relation to the working environment and act upon initiatives not functioning as intended. At the leader level, workshops will be conducted to train leaders and health and safety representatives in supporting and facilitating the intervention activities, to provide these groups with knowledge about the main features of the intervention and to furnish them with an opportunity for learning by sharing the experiences about the progress of the intervention. At the group and individual level, participatory cognitive mapping sessions will be carried out, allowing team members to discuss current work demands and resources (both physical and psychosocial) and to develop action plans to minimize demands and maximize the positive effects of the resources. At all levels, the intervention will be implemented with the existing organization of work (e.g. by utilizing time already allotted for team meetings and leader-employee talks). The company will be provided with visual boards to aid the implementation of action plans. All levels of the company will work together in ensuring that corrective action is taken regarding imbalances between demands and resources uncovered during the intervention. If required, the assistance of an experienced consultant will be available to the teams for implementing action plans.
In the second year, control group will also receive the similar intervention (explain above) while the intervention group will voluntarily participate in the intervention.
