Once hidden behind the veils of entrepreneurship, it is now clear that platforms are reshaping the world of work, and Amazon has been a forerunner in setting the trend. This book examines two key and contrasting Amazon platforms that differ in how they organize workers: its e-commerce platform and digital labor platform (Mechanical Turk). With access to the people who are working at the heart of these platforms, it explores how different working conditions alienate workers, and how, despite these conditions, workers organize within their political-economic contexts to express their agency in traditional and alternative ways. Written for social scientists studying and researching the platform economy, this is a timely and important analysis of work and workers on the (digital) shop floor.Drawing on interviews with Amazon workers and original empirical data, this book explores how different working conditions estrange and alienate workers, and how, despite these, workers find ways to organize and express their agency. Written for social scientists who are studying and researching the platform economy, this is a timely and important analysis of work on the digital shop floor.
