Abstract
Based on a case study of the South African food and canning industry at the Cape from 1940 to 1960, this article examines the conditions that fostered women's high level of involvement both in the trade union and in local and national political organizations concerned with gender and racial issues. Particularly important were women's prevalence in seasonal labor, which gave them few individual options for improving their situation at work; a progressive, nonracial trade union that encouraged close ties between family, work, and community and that kept women involved during the off-season; and an active political movement concerned to mobilize women against the threats to their work and family lives from the apartheid state. In addition, unlike women in many areas of Asia and Latin America, these women had a long tradition of productive labor and were not expected to refrain from visible public activity.
