January 2021: A new paper in Labour & Industry describes the distribution of labour by sex/gender across occupations in the Canadian workforce and examines changes in this distribution since 1991. Women’s increased labour force participation in Canada is a well-known trend over the past 40 years, and there is a perception that the gendered division of workplaces has decreased over time. This study found that over 40% of broad occupational categories were highly divided; three-quarters were mainly composed of men. For the most precise classifications, 58% of occupations were highly divided (78% mainly composed of men). The forces driving sex-segregated jobs include systems of gender essentialism, organizational hierarchies that favour men, and labour markets that are change-resistant.
