National Federation of Women Workers

The National Federation of Women Workers (NFWW) was a trade union in the United Kingdom of Great Britain and Ireland active in the first part of the 20th century. Instrumental in winning women workers the right to a minimum wage for the first time, the NFWW broke down barriers for women's membership in trade unions in general.
