Summary
This study improved a 42-hour/week irregular three-shift system for disabled workers, reducing fatigue and improving work-life balance. A participatory intervention led to a new, more regular shift rotation scheme.
Area of Science:
- Occupational Health
- Ergonomics
- Industrial Psychology
Background:
- Irregular three-shift systems with anti-clockwise rotation can cause worker fatigue, low back pain, and sleep disturbances.
- A disabled persons' facility reported issues with a 42-hour/week shift system, prompting management-labour discussions.
- Worker complaints included physical fatigue, high prevalence of low back pain, sleep deprivation, and irregular holidays.
Purpose of the Study:
- To improve an irregular three-shift work system through a collaborative intervention.
- To address worker complaints regarding physical fatigue, pain, sleep issues, and holiday irregularities.
- To design, implement, and evaluate improved shift rotation schemes.
Main Methods:
- A participatory intervention program involving group study, joint planning, and feedback.
- Methods included time study, questionnaires, and physiological assessments to analyze the existing system.
- Development of alternative shift schemes with more regular, clockwise rotation.
Main Results:
- The intervention led to the planning of alternative shift schemes with clockwise rotation.
- A trial period for shorter working hours was agreed upon.
- The process highlighted the effectiveness of stepwise intervention and participatory approaches.
Conclusions:
- Collaborative, stepwise interventions are crucial for improving shift work systems.
- Addressing a broad range of working life and health issues enhances worker well-being.
- Participatory processes involving management and labor unions are key to successful system improvements.
