Purpose – The purpose of this paper is to investigate the part that gender roles play in fathers’ work-family experiences. The authors compared two models (gender role as a correlate and as a moderator) and hypothesized that gender role beliefs play an important factor related to fathers’ experiences of work-family conflict. Design/methodology/approach – Participants completed an online survey that consisted of questions related to work and family experiences. The final sample consisted of 264 employed, married fathers. Findings – Results showed a relationship between traditional gender role beliefs and number of hours spent at work and at home. Additionally, number of work hours was related to time-based work-to-family conflict, but not strain-based work-to-family conflict. The results supported the expectation that work hours mediate the relationship between a father's traditional gender role beliefs and time-based work-to-family conflict. Research limitations/implications – Limitations of this study include the use cross-sectional and self-report data. Future research might want to expand the theoretical model to be more inclusive of fathers of more diverse demographic backgrounds, and assess the model with a longitudinal design. Practical implications – A key theoretical implication gleaned from the study is that work-family researchers should include the socially constructed variable of gender roles in their work-family research. Findings provide support for the contention that organizations need to ensure that mothers’ and fathers’ unique needs are being met through family-friendly programs. The authors provide suggestions for specific workplace strategies. Originality/value – This is one of the first studies that focussed on fathers’ experiences of the work-family interface. The results clarify that traditional gender role beliefs give rise to fathers’ gendered behaviors and ultimately work-family conflict.
