"An ERG wants to make all these really concrete changes often at a workplace but has no power to do that [...] They might have some funding or the ear of an executive, which we did at Uber, but ultimately it kind of relies on the good faith of an executive to work on whatever changes you want. ERGs kind of passively work against the idea of a union in that they're a way for you to kind of spend your energy without it turning into anything, which I'm really sad about, but that's what I've found in my experience."
