Whether Title VII is violated when sex was a motivating part of an employment decision, even though legitimate reasons also influenced the decision.
Holding
Yes. A plaintiff establishes a mixed-motive Title VII case by proving that sex played a motivating part in the challenged employment decision.
Reasoning
Title VII requires employers to treat sex as irrelevant to employment decisions, except in the narrow circumstance in which sex is a bona fide occupational qualification. The phrase “because of” sex does not require the plaintiff to prove that sex was the sole reason for an adverse decision. A decision may rest on both lawful and unlawful considerations.
The Court distinguished a mixed-motive case from an ordinary pretext case under McDonnell Douglas and Burdine. In a pretext case, the dispute is whether the employer’s stated legitimate explanation was the real reason for the action. In a mixed-motive case, both legitimate and illegitimate motives actually may have contributed to the decision, so asking for the single “true” reason is unhelpful.
Sex stereotyping is discrimination because of sex. An employer may not penalize a woman for failing to conform to expectations about how women should speak, dress, or behave. A workplace that demands aggressiveness but faults women for displaying it puts women in an impermissible double bind.
