not in silicon valley at least. i think even the engineers ( especially the engineers? ) are #vanlife 
i honestly think it’s just lack of familiarity. most american software engineers are coming from middle class or higher income families. probably not many of them have families in unions, with the exception perhaps of the teacher’s union
it’s just not something they see as part of their lives, and i don’t think they grok what benefits it would bring them. they are already showered with tangible benefits, because tech workers are in such high demand
contractors are the odd ones out. they have zero protection, and few benefits. but i’m sure it’s hard to organize when you’re gig’ing it.
