This book explores the precarious margins of contemporary labor markets. Over the last few decades, there has been much discussion of a shift from full-time permanent jobs to higher levels of part-time and temporary employment and self-employment. Despite such attention, regulatory approaches have not adapted accordingly. Instead, in the absence of genuine alternatives, old regulatory models are applied to new labour market realities, leaving the most precarious forms of employment intact. The book places this disjuncture in historical context and focuses on its implications for workers most likely to be at the margins, particularly women and migrants, using illustrations from Australia, the United States, and Canada, as well as member states of the European Union.
