This is a two-group cluster randomized controlled trial to compare an organizational intervention to control. The home care units will be treated as clusters to avoid contamination within units.
Control group: No intervention, their work will continue as usual without any instructions from researchers.
Intervention group: The intervention will consist of the operational managers distributing the physically strenuous shifts evenly between the workers in each home care unit. This will be achieved using a tool developed in Microsoft Excel which gives an overview over how much strain we expect each shift to have and gives a score on how well the operational manager distributes the strain between employees.
The intervention will last for approximately 4 months, depending on duration of pre and post measurements.
