The UK construction and transport sectors remain the most heavily male-dominated industries, showing minimal progress in women’s participation. Long and inflexible working hours presume a male model of the worker unconstrained by caring responsibilities. Yet the experiences of the minority of women who work in these sectors are of interest to those concerned with reducing occupational gender segregation. Sexuality is often overlooked in differentiating women’s experience of male-dominated work, and gender conflated with heterosexuality. Through examining the interaction of domestic circumstances and work arrangements of heterosexual women and lesbians, this article finds that atypical domestic circumstances may be required to support male-dominated work. Heterosexual ‘breadwinner’ norms were challenged by women’s capacity for higher earnings from male-dominated work, but often required strategies to manage associated emotions. Evidence from lesbian relationships indicates a possible shift from prioritization of financial self-sufficiency in the context of legal status for same-sex partnerships.
