Women are a dynamic force in the labor movement.
Of the AFL-CIO's four biggest unions, three are majority female. A fourth not in the AFL-CIO, the National Education Association, is the country's biggest union and has a heavily female membership. Of the two biggest AFL-CIO unions, the Teamsters has a growing number of women members as it branches out to represent workers in many industries. Less than half the UAW's members, for example, are auto workers. It also represents office workers and many others.
