I think we're seeing the beginnings of them, but they definitely have a headwind. It's definitely too early to say they're happening, but there's a possibility for the first time in my lifetime, IMO.
As far as unionization, there seems to be a trend of newsrooms organizing, I've seen a burger place trying to unionize where I live, and more and more people are talking about unionizing in the games space. With tech workers, we're not there yet, but efforts like the anti-ICE stuff could be a first step down that path.
As far as regulation, all the senators running for president support the Green New Deal, and so do a handful of congress members. And locally, several cities have passed laws providing paid sick leave, including in Texas.
These are frankly all pretty small, but taken together, I think they show that things could change.
