IMO you’re wrong to assume that forcing all labor actions to be illegal will unshackle a very powerful labor movement in the US. Surveillance is a hundred times what it was in the apogee of the labor movement. The thing that made the labor movement strong at that time was the material conditions of the time: America was rapidly industrializing and conditions were very poor for workers. Now, while conditions are obviously far from good, the neoliberals seem to have found a compromise for labor aristocracy to get enough shallow pleasures on borrowed money that US labor is nowhere near as radical as before, and offshoring industry has globalized the reserve army of labor (making the entire periphery scabs).

I expect that Teamsters and unions involved in logistics will continue to go hard because they have uniquely loadbearing functions.
