One of the things that happens when ppl go thru class struggle is that a good portion of them get pushed to the left and many get radicalized. Also- the strike itself being heard about changes the folks who hear about it.
The point is to build a larger, more radical movement.
If congress tries 2break railway workers power by trying to legally force them to take a deal they don't want-
Railway workers must disobey congress and strike anyway.
Congress and rail companies will cry about it and railway workers will win. It'll probably have 2b a wildcat.
