This book presents an evidence-based assessment of the impact of EU enlargement on industrial relations and social standards in old and new EU Member States. It combines chapters which give an overview of the process of enlargement/integration and comparative socio-economic data at EU and national level, with chapters that present an in-depth analysis of the impact of European integration on national industrial relations. These in-depth analyses cover both a number of old EU Member States in Western Europe and new Member States in Central and Eastern Europe. The book combines supranational European, Western and Eastern perspectives on the impact of European integration. A combination of solid empirical data and critical theoretically informed analyses, will be of great interest to researchers and students in various fields, including industrial relations, public sector employment relations, European Studies, socio-economic studies and political science.
