Working Women Unite was formed to create links between working women and the women's movement. The group focused on issues of women and work, and sought to create a relationship with trade unions that would further the position of women in the work force. Specifically, Working Women Unite sought to encourage the formation of women's committees within local unions, discuss strategies on how to organize in a non-union job, articulate feminist demands for working women to take to their unions when negotiating new contracts, and to recognize the value of all women's work regardless of whether it was paid or unpaid. The group also held conferences, workshops, and seminars on issues such as unpaid work, immigrant female workers, women in unions, women working in the home, equal pay for equal work, and the effects of video display terminals in the workplace.
Working Women Unite emerged from the British Columbia Federation of Women (BCFW) during its convention in 1977. During this convention the lack of representation for working women within the BCFW was addressed by a group of women, primarily members of the Service, Office, and Retail Workers Union of Canada (SORWUC), who met and formulated resolutions that were passed at the convention. It was not until 1978 that the group gained momentum with a broader base of support. Women from unions such as the British Columbia Government Employees Union (BCGEU), Canadian Union of Postal Workers (CUPW), Amalgamated Transit Union (ATU), SORWUC, Letter Carriers Union of Canada (LCUC), and Canadian Union of Public Employees (CUPE), along with non-unionized women, and women in the home, became involved with the group. Structurally, Working Women Unite remained within the BCFW, a federation of women's groups in British Columbia working toward liberation of women through fundamental social change.
