[Excerpt] Although women now constitute about one third of the members of labor unions in the United States, they are still barely visible in top leadership. To what extent are women currently making inroads in union leadership and what types of union responsibilities do they hold? Is there a glass ceiling? How do the career patterns of women unionists compare with those of men? What can unions do to facilitate their recognition? These are the key questions I examine in this article, drawing on past research supplemented by insights from union leaders I interviewed.
