Goldfield provides a statistical and historical examination of the erosion of unionization in the private sector. Based on National Labor Relations Board data, which serve as an accurate measure of union growth in the private sector, he argues that standard explanations for union decline--structural, industrial, occupational, demographic, and geographic changes--are insupportable or erroneous. He makes a compelling case that the decline is due to changing class relationships, determined corporate anti-unionism, lack of realism on the part of the unions, and a public view of unions as too powerful and untrustworthy. Goldfield maintains that by understanding the decline of U.S. labor unions it is possible to understand the conditions necessary for their rebirth and resurgence. ISBN 0-226-30102-8: $27.50.
