Description:This book investigates work relationships on the border between employment and self-employment by bringing together economic, sociological and legal research approaches. It answers the following questions: Why do firms deploy dependent self-employed workers? Why do individuals supply this form of work? By which informal and formal mechanism is dependency created? Who are the dependent self-employed workers? How can firms solve the control-flexibility dilemma in these work relationships? Which implications for social and labour market policy do we find?
