Unions in the 21st Century [PDF ebook] 
An International Perspective

This book presents a series of research essays on the state of unions in many different parts of the world. Written by leading researchers in the field it provides insights into the causes of union decline. But it goes beyond historical analyses to investigate the prospects for the future. Can unions organize in segments of the workforce such as the youth, women, low wage workers and those in the informal sector? Can unions network with other organizations such as NGOs nationally and internationally to gain power and influence?
