Revision with unchanged content. This book analyzes and describes occupational health and safety in the context of a changing professional world. The globalization of the professional world, diversified new requirements for employees, emerging occupational diseases and possible accidents on the job are the focus of this book. The emerging costs – whoever has to pay them – will explode in the future. Therefore, this work is intended for compulsory health insurance funds, national health services, employers’ mutual insurance associations, employers, labor unions, chambers of commerce and industry, and my colleagues. The European Union can only develop a complete solution for a social insurance agreement with the background of insurance coverage for business trips. This work covers the different involved institutions, national and international, that are responsible for the health of workers.
