National Women’s Trade Union League is established.

Founded by Mary Kenney O’Sullivan, Mabel Gillespie, and others, it created at the American Federation of Labor national convention at Faneuil Hall. The organization subsequently locates its headquarters at today’s 230 Stuart Street (then 7 Park Square). Mary Morton Kehew is the first president. Although not a union, it is affiliated with the American Federation of Labor. Its purpose is to help women workers form trade unions, provide workplace protections, relief, publicity, and general assistance for women’s unions on strike, and also to work for woman suffrage. The organization soon establishes a soup kitchen at 5 Boylston Place. The organization claims 424 members, including 275 female trade unionist and 150 professional allies by 1910. Eleven trade unions affiliate with it by 1911, most in the garment industries. By 1913, however, only 8,809 women belong to Boston Unions, just 8% of the female workforce.
