Just like the postal strike, there is no reserve workforce for rail laborers. They should strike, even if it is an illegal strike, and the three demands in this letter should be the minimum acceptable compromise. If they want to strike for more, like Medicare for all, or mass transit expansion, I'm all for that too, as should everyone in this sub be.
(Full disclosure, I am not a heavy rail worker)
