This book, based on the work of the fifth colloquium of the CNRS GDR "Companies under the Occupation", looks at the issue of work under the Occupation through the prism of the company. The focus is on three main issues: the impact of the requisitioning of labour by the STO (Service du travail obligatoire) on the structure of the labour market, the life of companies and the behaviour of workers; the consequences of German demands and Vichy policy on working conditions and wage levels; and the role of the new forms of staff representation provided for by the Labour Charter, trade unions at company level and the corporatist ideology of work. By extending the scope of the study to all companies, regardless of size, to all sectors of activity, including services, to all categories of workers, not forgetting women and foreigners, and by making ample room for international comparisons, this volume profoundly renews our knowledge of these dark years.
