Felix Frankfurter,
Local 1976, United Brotherhood of Carpenters and Joiners of America…
“ American Iron and Machine Works was engaged in a controversy with Local 850 of the International Association of Machinists, the bargaining representative of its production and maintenance employees, and a strike had been called at the company's plants. Picketing at the plants prevented the carriers that normally served American Iron from making pickup and deliveries, so American Iron hauled freight in its own trucks to the loading platforms of the carriers. ”
