To better understand the interplay between digital activism and feminist infrastructure, this study investigates #MeToo activism in the Swedish construction industry and green industry. Both are industries in transition characterized by a dissonance between formal incentives, that encourage women and others to work in environments previously dominated by white men, and the informal power structures hosting a toxic masculinity. Based on media texts and interviews with key persons from the industries, the article situates #MeToo in a local context and shows how it was embedded in a supportive social, cultural, and technical infrastructure. In both industries, at the time of #MeToo this feminist infrastructure was already in place consisting of: an awareness of the problem of sexual harassment and abuse, knowledge of feminist explanatory models, established feminist online networks, and a supportive feminist culture, which together with widespread digital and feminist literacy became instrumental in the organization of the movement. Social media connected activists and created a critical mass by supporting the uniting of conflicting identity positions around shared differences. The established feminist infrastructure meant that the #MeToo activism, by articulating a widespread affective dissonance, pushed open doors that were already half open and forced them wide. This can explain some of the movement's success in Sweden.
