Not really even… I wouldn’t even call Truman the most pro union president or whatever (he might also be the worst president? it is so hard to choose), but he tried to seize the steel industry away from its owners to avoid a strike… because he saw the industry as responsible, not the union… he also vetoed the taft-hartley act and refused to use it to break the strike

The cool and logical thing to do would have been to nationalize the railways, but that probably never even occurred to a single democrat politician
