This book explores the hidden world of everyday learning in the lives of manufacturing workers from a social perspective. It challenges the myth that everyday learning, despite its apparent openness and freedom, can be understood as class-neutral. Based on life-history interviews, selected ethnographic observations in homes and factories, and large-scale survey materials as well as the microanalysis of human-computer interaction, the analysis follows learning across the spheres of "working-class life" and draws on the author's personal experiences as a factory worker and academic.
