Belonging to a union can bring higher wages, fringe benefits, greater job security and, sometimes, training. But unions - still known as "brotherhoods" - often remain rigidly segregated by gender, despite the fact that sexual harassment and discrimination in employment are illegal. "Live Wire" is an in-depth case study of Local 3 of the International Brotherhood of Electrical Workers, arguably the most powerful and influential building trades local in the United States. Francine Moccio brings to life forty years of public policy failure that has resulted in restricted opportunities for women in skilled blue-collar jobs. "Live Wire" is a unique foray into the gender dynamics of one trade and one union in historical depth, based on extensive primary, secondary, and archival research. It contributes much-needed research about sex segregation in blue-collar occupations, particularly in unions and fraternal organizations. And it provides important insights into complex interactions of work, union, and family life.
