Deviations from heteronormativity affect labour market dynamics. Hierarchies of sexual orientation can result in job dismissals, wage discrimination and the failure to promote gay and lesbian individuals to top ranks. In this article, I report on a field experiment (144 job-seekers and their correspondence with 5549 firms) that tested the extent to which sexual orientation affects the labour market outcomes of gay and lesbian job-seekers in the United Kingdom. Their minority sexual orientations, as indicated by job-seekers’ participation in gay and lesbian university student unions, negatively affected their workplace prospects. The probability of gay or lesbian applicants receiving an invitation for an interview was 5.0 percent (5.1%) lower than that for heterosexual male or female applicants. In addition, gay men and lesbians received invitations for interviews by firms that paid salaries that were 1.9 percent (1.2%) lower than those paid by firms that invited heterosexual male or female applicants for interviews. In addition, in male- or female-dominated occupations, gay men and lesbians received fewer invitations for interviews than their non-gay and non-lesbian counterparts. Furthermore, gay men and lesbians also received fewer invitations to interview for positions in which masculine or feminine personality traits were highlighted in job applications and at firms that did not provide written equal opportunity standards, suggesting that the level of discrimination depends partly on the personality traits that employers seek and on organization-level hiring policies. I conclude that heteronormative discourse continues to reproduce and negatively affect the labour market prospects of gay men and lesbians.

This study is the first to use a field experiment to provide information on the relationship between women being lesbian and their hiring prospects in Greece. Data for 2007–8 support previous findings (in Canada and Austria) indicating that lesbians face hiring discrimination. The study finds that the estimated probability of lesbian applicants receiving an invitation for an interview is 27.7 percent lower than that for heterosexual women applicants. More importantly, the study shows that entry wage differentials assigned are inconsistent with the ascendant empirical claims (from the United States, the Netherlands, and the United Kingdom) that lesbians have higher market earnings. The study concludes that the negative effect of lesbian sexual orientation on wage outcomes in Greece is 6.1 percent. Given that legal actions in Greece have the potential to affect sexual-orientation minorities, it is important to understand the relationships between sexual orientation and the labor market.
