Under the supervision of Pr. Nathalie Lapeyre, my doctoral work focuses on conjugality, sexuality and sexual violence at work in three more or less feminized cultural professions (architecture, theater, video games). More specifically, my aim is to examine the ways in which conjugality, sexuality and sexual violence can affect professional career trajectories, and thus provide new explanations for the persistence of inequalities between men and women on the job market (leading to stagnation, bifurcation, deterioration in working conditions, new hardships, etc.). While these dimensions, relatively ignored in the French sociology of work, contribute to the downgrading of women’s careers, they reciprocally allow men to maintain their careers, or even to move up the career ladder. This thesis therefore sets out to renew our understanding of inequalities at work, going beyond the notion of “gender bias” (Acker, 1990), and seeking to demonstrate that professional cultures and ethos are just as much shaped by sexuality. To this end, various facets of sexuality are included in the analysis (love, couples, break-ups and divorces; ephemeral sexualities, “booty calls”, “one-night stands”; sexual orientation; extramarital affairs and polyamory; sexual violence, ranging from ambient harassment to rape). Another part of this work consists in analyzing the regulation of this sexuality at work, notably through legislative action and public policies put in place since the #MeToo movement, both at the level of the French state, and at the level of work organizations.
