Development of an African Working Class [PDF ebook] 
Studies in Class Formation and Action

Originally published in 1975, this volume reassesses the historical, political and social role of African workers and examines the extent to which a working class has formed and undertaken collective action in various parts of Africa. The book is based on primary historical sources or first-hand experiences. The contributors are linked by their belief in the legitimacy of action by organised workers to create a more just society.
