UAW Local 174 planned a leaflet campaign titled, "Unionism, Not Fordism", at the pedestrian overpass above Miller Road at Gate 4 of the
River Rouge Plant complex. The leaflet campaign was planned for the shift change, when many of the plant's 90,000 workers would be present. The leaflets to be distributed by the UAW demanded a work day plan of six hours for , in contrast to the
eight-hour day for then in place. The leaflets cited the success of the organizers at
General Motors,
Chrysler, and
Briggs Manufacturing Company, and promised that the UAW would "End the Ford Service System". At approximately 2 p.m., several of the leading UAW
union organizers, including
Walter Reuther and
Richard Frankensteen, were asked by a
Detroit News photographer, James R. "Scotty" Kilpatrick, to pose for a picture on the overpass, with the Ford sign in the background. While they were posing, men from Ford's Service Department came from behind and beat them. The number of attackers is disputed, but may have been 40. The Union breakers were identified as
Pinkertons. Frankensteen had his jacket pulled over his head and was kicked and punched. One union organizer, Richard Merriweather, suffered a broken back from the beating. ==Aftermath==
