title: Healthy shiftwork, healthy shiftworks.
abstract: Reflecting diversifying shift systems, extensive effort is put into managing shiftwork and reducing safety and health risks. It is accepted that shiftworkers are exposed to particular risks inherent in their irregular work schedules. This raises the question of how and to what extent we can ensure healthy work life for shiftworkers. In answering the question, we need to identify effective measures to improve both shiftworking conditions and the health of shiftworkers. Based on recent experiences in managing shiftwork, we note three directions of such measures: (a) comprehensive action to avoid risk-enhancing conditions based on general guidelines, (b) risk control as to workload, worksite ergonomics and risk reduction, and (c) support for flexible and restful working life. International standards are obviously relevant to these three aspects. Our own experiences in applying a set of ergonomic checkpoints to plant maintenance shiftwork demonstrate the usefulness of focusing on flexible work schedules and on multiple job-related factors such as night workload, ergonomic environment, resting conditions and training. There is a strong need for participatory planning and implementation of multi-area improvements as well as for relying on flexible schedules and autonomic teamwork. We may conclude that healthy shiftwork and healthy shiftworkers are compatible with each other only when certain conditions are met. In achieving this end, we need to combine (a) comprehensive measures to improve work schedules and job life, (b) strict risk management and (c) locally adjusted participatory steps for continual improvement.
