Labour relations had important connections with industrial performance in Greater Sao Paulo, the most important industrial centre in Brazil and Latin America, between 1945 and 1960. This book shows that the predominant industrial practices in terms of wages, working conditions and industrial training kept away activities based on quality and innovation which could produce sustained growth in the long term. As a result, the most important industrial centre in Brazil was locked into inefficient industrial practices and technologies, which have since marked the economic history of Brazilian industrialisation.
