While fathers in Sweden have had the right to paid parental leave since 1974, fathers take only one-fourth of all days of parental leave parents take. There is a strong cultural norm of involved fatherhood, so couples typically want to share leave more evenly than they in fact do. This article explores how the workplace might constrain fathers' use of this policy, a topic that receives much less attention than economic or attitudinal obstacles. Based on interviews with 56 employees in five large private sector companies, we found that fathers' opportunities for parental leave were reported to exist at the margins rather than at the center of their work lives. Workplace culture included deeply held normative expectations that made it difficult for fathers to choose to take leave, while several aspects of workplace structure negatively affected fathers' capabilities of taking leave. Workplace culture and structure seemed to be based on the gendered idea that the ideal worker will prioritize work and has limited caregiving responsibilities, which set meaningful limits to fathers' ability to take even the two months of nontransferable leave granted by legislation. Future research should explore how formidable these obstacles are in a more representative sample of companies. Contemporary fathers are expected to be more involved in childcare than earlier generations (Coltrane, 2009). The right to government-mandated paid parental leave is a policy that could increase men's involvement in early childcare, without sacrificing their labor market status. Parental leave for fathers is also a policy that can promote gender equality, since fathers who take parental leave are more likely to share childcare with partners after their leaves are over (
