Floors, walls, windows, mirrors, and bathroom fixtures might be adequately cleaned with some form of an extension tool to reduce bending and over-stretching. However, the demand for spotless cleanliness and hygiene, management often requires their cleaning staff to spend extra time and effort cleaning by kneeling, leaning, squatting, crouching, slouching and stretching. These postures will in time contribute to new musculoskeletal injuries and aggravate old ones. New approaches, other than strictly ergonomic ones, need to be investigated. For example, action can be taken from the administrative level.
Job rotation is one possible approach.
It requires workers to move between different tasks, at fixed or irregular periods. However, it must be a rotation where workers do something completely different. Different tasks must use different muscle groups to allow muscles already stressed to recover. Another approach is job enlargement. This increases the variety of tasks built into the job.
