Speaking of "relentless propaganda" (quoting the parent post), ever notice that every time the example used by pro-union folks is the Screen Actors' Guild or sports teams union? It's almost as if its a canned talking point.
You might also notice how none of these posters can point to any engineering unions (there's barely any in the US and it takes much more smarts to get an engineering degree than become a coder) or have the guts to use technical workers' unions like the Communications Workers of America as their example? Think very hard about why that is.
