Men’s limited movement into female occupations has been identified as a key barrier to future declines in occupational sex segregation and achieving greater gender equality. So why are men so reticent to enter jobs normatively regarded as female? Drawing from qualitative interviews with multiple stakeholders in four female dominated occupations in Australia, this article documents the processes that influence men’s employment in gender atypical jobs. Gender essentialism is central to many processes that generate and/or stall changes in men’s representation in female dominated occupations. While gender essentialism’s role in producing and reproducing occupation sex segregation is well known, its role in reducing occupational sex segregation is a critical process which has previously received limited attention. The paper details gender essentialism’s integrative function.
