This article discusses the persistence of a gender gap among university-based academics, despite the development of equity policies and "family-friendly" initiatives. Over four decades of research are reviewed from the liberal states of Australia, Canada, New Zealand, USA and the UK, including my own qualitative interviews in Canada in 1973 and in New Zealand in 2008. The paper summarizes some of the structural, relational and interpretive factors contributing to the perpetuation of the gender gap. I argue that academic work has been influenced by similar global trends visible in other workplaces and that academics share the prevalent patterns of gender relations contributing to the gender gap. Despite over four decades of social change, including policy initiatives to improve the status of academic women, this article shows that the gender gap continues in these countries for similar reasons.
