The SWW was a grassroots, feminist organization of female wage earners which operated from 1978 to 1990. SWW was formed by an alliance of trade union women and community-based feminists. Members of SWW came from many different political backgrounds, including the Waffle, the New Democratic Party, various Communist, Trotskyist and Marxist-Leninist parties, the women’s movement on university campuses and women’s centres, and the trade union movement. Some SWW women were also involved in the organizing drives of the Service, Office and Retail Workers’ Union of Canada (SORWUC), a feminist trade union active in Saskatchewan and BC. SWW originated because an increasing number of women were joining the workplace and becoming both unionized and mobilized.
