Drawing from experience internationally, on recent and important developments in regulatory theory, and upon models and approaches constructed during the author's empirical research, this book addresses the question: how can law influence the internal self-regulation of organisations in order to make them more responsive to occupational health and safety concerns? In this context, it is argued that Occupational Health and Safety management systems have the potential to stimulate models of self-organisation within firms in such a way as to make them self-reflective and to encourage informal self-critical reflection about their occupational health and safety performance. This book argues for a two track system of regulation under which enterprises are offered a choice between a continuation of traditional forms of regulation and the adoption of a safety management system-based approach on the other. The book concludes with a discussion of the use of criminal and administrative sanctions to provide organisations with incentives to adopt effective Occupational Health and Safety management systems. The book proposes a wider range of criminal sanctions and sentencing guidelines to ensure employers receive sentencing discounts where they have introduced effective management systems.
