The aim of this book is to examine the ways that contemporary organizing draws increasingly on the affective dimensions of worker sociality. The book explores the different ways that such kinds of affectivity have come to the fore in the contemporary ‘post-bureaucratic’ modes of work that necessitate high levels of social interdependence. Drawing on four detailed case studies the book examines the ways in which affectivity institutes an intensity of interaction in the workplace that involves workers in socially-negotiated processes through which they not only revisit, (re)define and (re)produce their own tasks, but also their own identities and interpersonal relationships.
