22 necessary to the result if a member of the opposite sex might face the same outcome from the same policy?

What the employers see as unique isn’t even unusual. Often in life and law two but-for factors combine to yield a result that could have also occurred in some other way. Imagine that it’s a nice day outside and your house is too warm, so you decide to open the window. Both the cool temperature outside and the heat inside are but-for causes of your choice to open the window. That doesn’t change just because you also would have opened the window had it been warm outside and cold inside. In either case, no one would deny that the window is open “because of” the outside temperature. Our cases are much the same. So, for example, when it comes to homosexual employees, male sex and attraction to men are but-for factors that can combine to get them fired. The fact that female sex and attraction to women can also get an employee fired does no more than show the same outcome can be achieved through the combination of different factors. In either case, though, sex plays an essential but-for role.

At bottom, the employers’ argument unavoidably comes down to a suggestion that sex must be the sole or primary cause of an adverse employment action for Title VII liability to follow. And, as we’ve seen, that suggestion is at odds with everything we know about the statute. Consider an employer eager to revive the workplace gender roles of the 1950s. He enforces a policy that he will hire only men as mechanics and only women as secretaries. When a qualified woman applies for a mechanic position and is denied, the “simple test” immediately spots the discrimination: A qualified man would have been given the job, so sex was a but-for cause of the employer’s refusal to hire. But like the employers before us today, this employer would say not so fast. By comparing the woman who applied to be a mechanic to a man who applied to be a mechanic, we’ve quietly
