Educational and intervention strategies for improving a shift system: an experience in a disabled persons' facility.
The improvement of an irregular three-shift system with anti-clockwise rotation of workers of a disabled persons' facility covering 42 h a week was a subject for management-labour debate. Workers were complaining of physical fatigue, high prevalence of low back pain, sleep shortages associated with short inter-shift intervals, and irregular holidays. With the co-operation of trade union members, an educational and intervention programme was designed to analyse, plan, and implement improved shift rotation schemes. The programme consisted of (a) a group study on the existing system and effects on health and working life; (b) joint planning of potential schemes; (c) communication and feedback (d) testing and evaluation; and (e) agreement on an improved system. The group study was undertaken by means of time study, questionnaire and physiological methods, and the results were jointly discussed. This led to the planning of alternative shift schemes incorporating more regular, clockwise rotation. It was agreed to stage a trial period with a view to shorter working hours. This experience indicated the importance of a stepwise intervention strategy with frequent dialogues and a participatory process focusing on the broad range of working life and health issues.
