The 1909 strike at New York city's triangle shirtwaist strike demonstrated that women workers could create solidarity across social and ethnic lines.
The Uprising of the 20,000, also known as the New York Shirtwaist Strike of 1909, was a labor dispute that mostly affected Jewish women who worked in New York shirtwaist manufacturers. The strike was the biggest by female American employees to that point. The strike began in November 1909 under the direction of Clara Lemlich and the International Ladies' Garment Workers' Union, with assistance from the National Women's Trade Union League of America (NWTUL). The NWTUL and the factory owners reached a settlement in February 1910, which resulted in better pay, hours, and working conditions. The Triangle Shirtwaist Factory Fire, which exposed the hardship of immigrant women working in hazardous and challenging conditions, occurred only a year after the strike came to a conclusion.
