Care work is typically women’s work. Only a third of the staff on the wards hold a full-time position in Norway. Experience shows that the rota system is the starting point for unwanted part-time work, too small a workload and dissatisfaction at work. The empirical basis for this chapter is an R & D project called the Rota System as Innovation. The purpose of using the concept of innovation was two-fold: partly to draw attention to women’s work and working time arrangements as a relevant and important innovation arena, and partly to use the energy of such a term within this sector to increase awareness about the innovation by creating a full-time culture in this kind of work. The results are related to developing new knowledge, a new rota system, and experience of using the concept of innovation as a tool for promoting change.
