Although women have made tremendous gains at work, a striking degree of sex segregation still exists. For a generation of women who were working in low-paying, administrative support positions during the promising era of Title VII, affirmative action did not offer upward mobility. In the 1970s, as employers and regulators began implementing affirmative action amid the gendered structure of internal labor markets, women who were already in clerical roles remained outside the managerial pipeline. Women in 9to5, the National Association of Working Women, sought to bridge the gap between female-dominated clerical and male-dominated managerial ladders using collective action. Yet business and government did not enforce affirmative action such that the clustering of women in low-paid clerical positions constituted discrimination on the basis of sex. Work experience on the clerical ladder remains inadequate training for positions on the managerial ladder.
