Working women and their issues played a central role in the women’s movement in the decades following World War II. Feminists lobbied, litigated, and engaged in direct action for workplace fairness. Working women, especially those in unions, joined feminist organizations and established their own organizations as well. There were fault lines within the women’s movement over the issues, strategies, and level of commitment to the causes of working women. In the first two decades after 1945, the unionists and liberal reformers who constituted the so-called Women’s Bureau Coalition (named after the U.S. Women’s Bureau) opposed the mostly affluent and conservative members of the National Woman’s Party for their support of the Equal Rights Amendment, supporting instead protective laws and policies that treated women differently from men in the workplace. With the arrival of second-wave feminism in the 1960s and 1970s, “labor feminists” clashed with the middle-class professional women at the helm of newly formed feminist organizations. As support for gender equality transformed employment practices, some labor feminists sought to retain (or extend to men) selected protective measures introduced in the early 20th century to shield women workers from the worst aspects of wage labor. In the face of harsh economic conditions in the 1970s, labor feminists again opposed other feminists for their efforts to modify the union practice of “last hired, first fired” as a way of retaining affirmative-action hiring gains.
In recent decades feminists have focused on equity measures such as comparable worth and pregnancy leave as means of addressing the unique challenges women face. In addition they have expanded their concern to lesbian and transgender workers, and, increasingly, to the needs of immigrant workers who make up an increasingly percentage of the working population.
