The latter employee mentioned here is actually male, so I wonder how this claim will play out in court, considering that he's not really in the sex category that his lawsuit claims has been discriminated against.
The only two ways to ensure that "no protected group sees a disproportionate impact" are to make layoffs illegal (probably what some people would like, but impossible), or to require companies to do a lot of demographically-based bias in the name of avoiding it.
