While working at the Heinemann Electric factory outside
Alexandra, Komape-Ngwenya was recruited by the
Metal and Allied Workers' Union (MAWU) in 1974. For example, to challenge the presumption that she would be responsible for domestic chores in the office, she drew up a chore roster for the men. In addition, Komape-Ngwenya argued that male unionists were rarely concerned with the problems faced by women workers; she said that
parental leave was a rare issue on which women received men's support, because the men hoped to be granted paternity leave and "have a holiday and a rest from work". As an organiser, Komape-Ngwenya advocated for certain women's issues, such as the unionisation of women night-cleaners and their resistance to the sexual exploitation of their supervisors. As part of her union work, in 1978, Komape-Ngwenya was asked to establish the Transvaal branch of the
Transport and General Workers' Union (TGWU, until then based in
Natal); she remained active in TGWU until 1985. During this period, she was involved in founding the
Federation of South African Trade Unions in 1979 – and particularly in establishing the federation's women's committee – and later the
Congress of South African Trade Unions in 1985. The following year, Komape-Ngwenya returned to the rural Transvaal and worked as a full-time fieldworker for the
Black Sash's Transvaal Rural Action Committee, which at the time was focused on supporting those affected by
forced removals. Drawing on her experience with the committee, Komape-Ngwenya co-founded the
Rural Women's Movement in 1986. The movement functioned as an umbrella lobby group and was a prominent grassroots voice in the
negotiations to end apartheid; among other things, the movement opposed proposals to exempt traditional leadership from
gender equality prescripts. == Post-apartheid political career ==
