When an injunction prohibited miners from picketing their wives took over the picket lines &#x2014; an unprecedented act that disrupted mining families but ultimately ensured the strikers' victory in 1952. In <i>On Strike and on Film</i> Ellen Baker examines the building of a leftist union that linked class justice to ethnic equality. She shows how women&#x2019;s participation in union activities paved the way for their taking over the picket lines and thereby forcing their husbands and the union to face troubling questions about gender equality.<br/><br/>Baker also explores the collaboration between mining families and blacklisted Hollywood filmmakers that resulted in the controversial 1954 film <i>Salt of the Earth</i>. She shows how this worker-artist alliance gave the mining families a unique chance to clarify the meanings of the strike in their own lives and allowed the filmmakers to create a progressive alternative to Hollywood productions. An inspiring story of working-class solidarity Mexican American dignity and women&#x2019;s liberation <i>Salt of the Earth</i> was itself blacklisted by powerful anticommunists yet the movie has endured as a vital contribution to American cinema.
