On the evening of November 22, 1909, there was a great mass meeting of workers held at Cooper Union in New York. Samuel Gompers, President of the American Federation of Labor, presided, and the stage was well filled with members of the Women's Trade Union League. The meeting had been called by the League in conjunction with Shirt-Waist Makers' Union, Local 25, to consider the grievances of shirt-waist makers in general, and especially of the shirt-waist makers in the Triangle factory, who had been, for more than two months, on strike.

The story of the strike, the causes that led up to it, and the bitter injustice which followed it were rehearsed in a dozen speeches. It was shown that for four to five dollars a week the girl shirt-waist makers worked from eight in the morning until half-past five in the evening two days in the week; from eight in the morning until nine at night four days in the week; and from eight in the morning until noon one day in the week—Sunday.

The shirt-waist makers in the Triangle factory, in hope of bettering their conditions, had formed a union, and had informed their employers of their action. The employers promptly locked them out of the shop, and the girls declared a strike.

The strike was more than two months old when the Cooper Union meeting was held, and the employers showed no signs of giving in. It was agreed that a general strike of shirt-waist makers ought to be declared. But the union was weak, there were no funds, and most of the shirt-waist makers were women and unused to the idea of solidarity in action. Could they stand together in an industrial struggle which promised to be long and bitter?

President Gompers was plainly fearful that they could not.

Suddenly a very small, very young, very intense Jewish girl, known to her associates as Clara Lemlich, sprang to her feet, and, with the assistance of two young men, climbed to the high platform. Flinging up her arms with a dramatic gesture she poured out a flood of speech, entirely unintelligible to the presiding Gompers, and to the members of the Women's Trade Union League. The Yiddish-speaking majority in the audience understood, however, and the others quickly caught the spirit of her impassioned plea.

The vast audience rose as one man, and a great roar arose. "Yes, we will all strike!"

"And will you keep the faith?" cried the girl on the platform. "Will you swear by the old Jewish oath of our fathers?"

Two thousand Jewish hands were thrust in air, and two thousand Jewish throats uttered the oath: "If I turn traitor to the cause I now pledge, may this hand wither and drop off from this arm I now raise."

Clara Lemlich's part in the work was accomplished. Within a few days forty thousand shirt-waist makers were on strike.
