Sex and Gender Discrimination: What You Need to Prove
Sex discrimination under Title VII encompasses far more than treating women worse than men. It covers gender stereotyping, glass ceiling practices, pay disparities, different application of standards based on gender, and — since the Supreme Court's 2020 Bostock decision — discrimination based on sexual orientation and gender identity.
Sex discrimination under Title VII encompasses far more than treating women worse than men. It covers gender stereotyping, glass ceiling practices, pay disparities, different application of standards based on gender, and — since the Supreme Court's 2020 Bostock decision — discrimination based on sexual orientation and gender identity. The scope of sex discrimination claims has expanded significantly over time, and workers often don't know the full range of what the law covers.
What Title VII Prohibits
Title VII prohibits discrimination "because of sex" in all terms and conditions of employment. The Supreme Court in Price Waterhouse v. Hopkins (1989) held that sex stereotyping — judging an employee for failing to conform to gender norms — is sex discrimination. A woman penalized for being "too aggressive," a man penalized for being insufficiently masculine, a worker penalized for defying gender expectations in appearance or behavior — all of these fall within Title VII's prohibition. In Bostock v. Clayton County (2020), the Court held that discrimination based on sexual orientation or gender identity is necessarily discrimination based on sex. This ruling extended Title VII's reach to LGBTQ+ workers without requiring separate legislation.
What You Need to Prove
A sex discrimination case follows the standard McDonnell Douglas framework: prima facie case (member of a protected class, qualified, adverse action, inference of discrimination), employer's legitimate reason, and pretext showing. In sex cases, the inference of discrimination is typically established through comparators of the opposite sex who were treated more favorably in equivalent circumstances. For gender stereotyping claims, the plaintiff shows that the employer made employment decisions based on the employee's failure to conform to gender-based expectations — not just that the employer was unfair, but that the unfairness was tied specifically to gender norms.
Evidence That Moves Sex Discrimination Cases
Direct comments about gender, statements reflecting gender stereotypes from decision-makers, and comparator evidence are all significant. Statistical evidence showing women (or men) are underrepresented in a level, category, or advancement track — when controlling for relevant qualifications — can support systemic claims. The decision-maker's prior conduct toward employees of the same sex and the employer's general culture around gender are fair game. Pay disparity claims — whether pursued under Title VII or the Equal Pay Act — require specific evidence of pay differences for substantially equal work, discussed separately in the Pay Discrimination deep dive.
