Plain English Summary
Background and study aims
Organizational workplace interventions to improve employee health aim to reduce health hazards and enhance health promoting working conditions. In particular, organizational workplace interventions which involve participation of workers may have a positive impact on employees’ health, since these types of interventions draw on workers’ deep knowledge of the working procedures and because they are likely to improve employees’ job control. This study is looking at a programme designed to improve the work environment by focusing on improving the performance of core job tasks. It is expected that focusing on core job tasks will reduce work stress, and that reduced work stress will result in favorable outcomes with regard to job satisfaction, exhaustion, sleep disturbances, short term sickness absence, and parents’ satisfaction. Results from organizational workplace intervention studies are, however, inconsistent, and only few studies have used a strong research design. Therefore, the aim of this study is to use a strong research design to examine whether a workplace intervention focusing on employees' work tasks can increase employees' well-being, reduce their short-term sickness absence, and increase parents’ satisfaction.
Who can participate?
Male and female employees in all age and job groups employed in one of the 78 participating pre-schools.
What does the study involve?
Participating workplaces (pre-schools) are randomly allocated to one of two groups. Workplaces in the first group continue to work as normal for the duration of the study. Workplaces in the second group take part in the workplace intervention. The program consists of seminars and workshops. Based on consultants implementation support, seminars, and workshops, local intervention activities were developed and implemented in workplaces. A work environment consultant being assigned to all workplaces for the full implementation period.
What are the possible benefits and risks of participating?
If successful, the intervention would result in an increased level of job satisfaction, decreased levels of exhaustion and sleep disturbances, lower risk of short-term sickness absence, and increase parent satisfaction. The intervention was not expected to pose any risks on participants.
Where is the study run from?
The study is run by The Children and Youth Administration and takes place in 78 pre-schools within the Children and Youth Administration of the Municipality of Copenhagen, (Denmark)
When is study starting and how long is it expected to run for?
September 2010 to September 2013

Study hypothesis
1. The workplace intervention, a participatory organizational-level occupational health intervention aiming to improve the working environment by focusing on core job tasks, will lead to increased job satisfaction and reduced exhaustion and sleep disturbances in the intervention group compared to the control group
2. The workplace intervention, a participatory organizational-level occupational health intervention aiming to improve the working environment by focusing on core job tasks, will lead to a lower risk of short-term sickness absence in the intervention group compared to the control group
3. The workplace intervention, a participatory organizational-level occupational health intervention aiming to improve the working environment by focusing on core job tasks, will lead to higher user satisfaction among parents in the intervention group compared to the control group

Intervention
78 workplaces (pre-schools) will be randomized to either intervention group or control group by a statistician at The Danish National Research Centre for the Working Environment using a random number generator.
Control group: Workplaces will continue to work as usual for the duration of the study (25 months)
Intervention group: A working environment consultant will be assigned to each pre-school in the intervention group. Further, a steering group in each intervention group pre-school will receive implementation support from the working environment consultant for the full implementation period. The intervention consists of intervention activities for all steering group members, i.e. seminars and workshops focusing on how to develop and implement intervention activities tailored their own workplace using a participatory approach, change management training, workplace culture, and tools to evaluate achievements. Based on seminars, workshops, and consultants’ implementation support, the steering groups will develop and implement intervention activities tailored their own workplace involving all employees.
The total duration of the intrvention is 25 months. The total duration of follow-up is 2 years for self-reported employee measures, 31 months for register-based employee measures and finally, 1 year for self-reported parents’ measures.
