US railroad workers are on the verge of a national strike. The sentiment for a strike among 100,000 railroaders is overwhelming. In July, engineers voted to authorize a strike by 99.5 percent. Workers are fighting against the attempts to impose a settlement from a Biden-appointed Presidential Emergency Board (PEB) that does not meet their demands. The Biden administration intervened through the National Mediation Board, which recalled union officials to Washington for three days of mediated talks. Workers have already taken the critical step of forming the Railroad Workers-and-File Committee, which has met with hundreds of workers writing in writing to join and get involved. Workers want to end the intolerable conditions workers are determined to end once and for all, writes John Avlon. . . .
