I think there's something to be said for medium sized companies. I work for one that's trying to grow and become much larger, but it's decidedly not big. Our execs though actually seem like pretty cool people, and the CEO seems to be a legitimately good person. He's generally been open and honest, and he's told stories that make me think he does actually value employees as people.
He was talking about gay rights and the value of diversity during our weekly company forum the other day, and I asked him about our company's support for DEI given the political pressure from conservatives to abandon it. He said he didn't give a damn about them, and doing the right thing was more important. I don't agree with everything he's done -- we've had layoffs, and morale isn't great, and we're totally broke -- but I respect that he actually seems to mean what he says. And even when we had layoffs, executives and management weren't safe either.
I think a lot of what it comes down to is the genuineness of leadership and how closely tied they are to rank and file employees. That's easier at small and medium companies. Large companies also tend to attract greedy robber barons.
