The purpose of this paper is to create an understanding of the negotiation process behind the decision of who will stay at home with a sick child and to develop the knowledge of the mechanisms considered to affect the negotiation process, in particular, the mechanisms likely to contribute to an uneven use of care leave. In the study six interviews were conducted with three sets of parents. These interviews were then analysed with Janet Finch’s (1989) definition of negotiation of family responsibilities. The study finds that the negotiation on care leave is a result of the negotiation of the shared view of reality. This image is in turn influenced by a number of institutional aspects such as job design, relative resources, and the couple's ideological points. Previous studies that found that relative resources, converted to salary, affects the distribution greatest. Instead the results of this study points out that the nature of work is most important for how parents divide their care leave. If one parent have work that easier can be pushed forward or to be away from, the latter tend to be the one who stays at home. This arrangement, however, is affected by a number of other factors. For example, the ideas of a fair distribution of care leave counteract this tendency.
