In June 1934, Congress amended the Watson-Parker Railway Labor Act so it explicitly included non-operating train personnel and sleeping car companies. Senator Dill sponsored the new act since he thought Pullman porters and maids should be black. A jurisdictional dispute between the Order of Sleeping Car Conductors and the Brotherhood of Sleeping Car Porters had to be first settled in the American Federation of Labor, but the effect was to quadruple membership in the Brotherhood. Black workers could now join the union without fear of losing their jobs.
