Work, employment and their regulation have been facing profound challenges in the digital economy. This book analyzes the resulting dynamics of autonomy and control on crowdworking platforms in an interdisciplinary perspective, which brings together law, sociology and organisation studies. On the basis of empirical studies of crowdworking in Germany, the authors find crowdworking platforms to be recursive and adaptive. Therefore, regulators should not make the mistake of reducing them to placing services.
