Regulating the risks associated with economic activities is a feature of modern societies and one in which the state increasingly seeks to co-opt the regulatory powers of corporations. This study examines the impact of a system of enforced self-regulation on the corporate life of British Railways. It uses this case study of occupational health and safety regulation to focus on broader theoretical and empirical discussions of regulation, risk, and corporate activities. A central organizing perspective of this book is that regulation is a form of risk management. It examines how workplace risks in modern societies are managed by businesses and the individuals within them and considers what influence the law has in this. The tensions between the constitutive and controlling aspects of regulatory law are analyzed with reference to in-depth empirical data about corporate and individual compliance and non-compliance. Related concerns about the social control of organizational and economic life are explored and their policy and theoretical implications examined.
