Book excerpt: This book investigates four core characteristics of occupational health and safety legal systems in order to provide a comparative and critical analysis of the similarities and differences in protecting the health and safety of workers at the workplace. In addition to analysing the health and safety regulations, the book addresses corresponding oversight and enforcement mechanisms. It compares and contrasts five different legal systems, namely those of the EU, the Netherlands, the UK, Sweden and China. Beyond offering an overview of the modes of OHS regulation, instruments and legal enforcement practices, the book helps to answer the question of how to improve working environments in order to protect workers from all kinds of dangers encountered at the workplace. The intended readership includes researchers with a background in labour law, comparative law, Chinese law and/or European Union law.
