Maybe most intuitively, the employers assert that discrimination on the basis of homosexuality and transgender status aren’t referred to as sex discrimination in ordinary conversation. If asked by a friend (rather than a judge) why they were fired, even today’s plaintiffs would likely respond that it was because they were gay or transgender, not because of sex. According to the employers, that conversational answer, not the statute’s strict terms, should guide our thinking and suffice to defeat any suggestion that the employees now before us were fired because of sex. Cf. post, at 3 (Alito, J., dissenting); post, at 8–13 (Kavanaugh, J., dissenting).
But this submission rests on a mistaken understanding of what kind of cause the law is looking for in a Title VII case. In conversation, a speaker is likely to focus on what seems most relevant or informative to the listener. So an employee who has just been fired is likely to identify the primary or most direct cause rather than list literally every but-for cause. To do otherwise would be tiring at best. But these conversational conventions do not control Title VII’s legal analysis, which asks simply whether sex was a but-for cause. In Phillips, for example, a woman who was not hired under the employer’s policy might have told her friends that her application was rejected because she was a mother, or because she had young children. Given that many women could be hired under the policy, it’s unlikely she would say she was not hired because she was a woman. But the Court did not hesitate to recognize that the employer in Phillips discriminated against the plaintiff because of her sex. Sex
