Research on gendered identities in management has exploded over the past three decades. The focus on gender obscures the place of sexuality in gendered theory. In this article theories of gender as 'object', 'subject' and as social processes are used as interpretative frames to explore the ways in which gender and sexuality are enacted by lesbian managers. Their narratives demonstrate that managing gender was experienced primarily as managing heterosexuality. Disjunctions in identity positions revealed that heterosexual assumptions provide the foundation of gender. Reframing gender as 'heterogender' foregrounds heterosexuality and gender as intertwined and provides another layer to understanding how gender is 'done' in management.
