I did Masters' research on this well more than a decade ago, how diversity injection is best used to break up unions and solidarily of a workforce leading to a cheaper and less demanding human resource to be used in greater excesses. Even back then, basically all the research was in basic agreement on this, "yup, you want to have employees at each-other's throats over their low pay, not at your throat, so you do lots of diversity initiatives!", it was standard knowledge. It also reduced productivity, but most workforces were overstaffed a bit anyways so a bit of lost theoretical maximum didn't really hurt.

Employees worried that there's a gender or race pay gap don't worry that you're paying them piss-all, and they don't trust their coworkers so they won't unionize as readily.

This was BEFORE Occupy Wall Street, mind you, so the sudden obsession during that for the Left to be race-and-gender-baiting isn't really mysterious, it's simple injection of a philosophy that they knew worked really well to sabotage and break down the movement. Alas, I don't think the Powers That Be realized just how effective their agent's sabotage was, given the damages it is causing now.
