[3] At the UGW's 1914 convention in Nashville, Tennessee, a number of large urban locals, with stronger Socialist loyalties and more willingness to strike, and who represented a full two-thirds of the national membership, split off to form the rival Amalgamated Clothing Workers of America under Hillman's founding leadership.The union came to national attention with the 1910 Chicago Garment Workers' Strike, which had started as a spontaneous strike on September 22, by a handful of women workers at Hart Schaffner & Marx.Future union president Sidney Hillman was a rank-and-file leader, and lawyer Clarence Darrow was involved with the settlement negotiations.The action not only pitted workers against management and against Chicago police on horseback, it also exposed divisions in the union—namely that the organization did not support its unskilled members.[5] Later UGW strikes included one in February, 1913, in Rochester, New York, where striker Ida Braiman was killed and others wounded by gunfire.
