They kind of kick-started this years huge labor push. Sure, it was bubbling up for a while before the rail unions decided to take action but they were the first “big” players to threaten a strike in a while. It’s easy to say that from the sidelines after the fact but they were being vilified by national media 24/7 for weeks, getting a bunch of pressure from Congress and being threatened to have the book thrown at them if they decided to strike. They were early to the party and didn’t have all of it’s completely understandable.
It’s also completely valid to criticize Biden for not doing enough when it really mattered, he could’ve put more pressure on Congress, he could’ve visited the workers and given his approval. He’s clearly capable of these things when it suits his interests, why didn’t he do any of that for the rail unions? Surely they could’ve used the help. Why was “working in the background” good enough for them but all of a sudden it’s insufficient for the UAW?
