to organizing women into trade unions and ensuring successful collective bargaining for them. The WTUL also emphasized the passing of labor standardization legislation as well as promoting the education of women in the workforce. The WTUL counted a diverse group of people amongst their ranks, from educated women reformers of a mostly white, Protestant, and native-born background, to young women workers which included a large number of immigrants, namely Jews, Italians, and Irish. Among the more affluent of their numbers were figures like Eleanor Roosevelt, Jane Addams, Florence Kelly, Margaret Dreier Robins, and Mary Morton Kehew, while the working class members of the WTUL included figures like Mary Kenney O'Sullivan, Rose Schneiderman, Pauline Newman, Fannia Cohn, and Clara Lemlich. The heyday of the League came between 1907 and 1922 under the presidency of Margaret Dreier Robins. During that period, the WTUL led the drive to organize women workers into unions, secured protective legislation, and educated the public on the problems and needs of working women. Support for Union Organizing The League supported a number of strikes in the first few years of its existence, including the 1907 telegrapher's strike organized by the Commercial Telegraphers Union of America. The WTUL played a critical role in supporting the Uprising of the 20,000, the New York City and Philadelphia shirtwaist workers' strike, by providing a headquarters for the strike, raising money for relief funds, soup kitchens and bail for picketers, providing witnesses and legal defense for arrested picketers, joining the strikers on the picket line, and organizing mass meetings and marches to publicize the shirtwaist workers' demands and the sweatshop conditions they were fighting. Rose Schneiderman in particular led efforts during the great garment strike of 1909. Working with the League's New York City branch, the NYWTUL, she was able to successfully organize over one-hundred shirtwaist makers, coordinated events which helped fund the strike, and persuaded women to join their local branch of the International Ladies’ Garment Workers’ Union (ILGWU). Some observers made light of the upper-class women members of the WTUL who picketed alongside garment workers, calling them the "mink brigade". Furthermore, Schneiderman’s Socialist views and actions during the strike also highlighted the tenuous relationship between the wage earners and the middle-class women which made up the WTUL. These distinctions split strikers from their upper-class benefactors as well: a contingent of strikers challenged Alva Belmont concerning her reasons for supporting the strike.
