Research on work-family balance has seen flexible work arrangements as a key solution for reconciling work and family, but it has given contradictory results in regard to fathers. This article focuses on flexible parental leave for fathers in Norway, which until now has rarely been studied. Based on interviews with 20 fathers, the article explores their experiences with flexible organization of the leave, which provides them with a menu of choices, and considers how it affects their caring. Findings show that it allows work to invade care, produces a double stress and promotes half-way fathering. Flexible use of the father’s quota tends to confirm fathers as secondary carers instead of empowering them as carers.
