This book provides the first systematic assessment of trends in inequality in job quality in Britain in recent decades. It assesses the pattern of change drawing on the nationally representative Skills and Employment Surveys (SES) carried out at regular intervals from 1986 to 2012. These surveys collect data from workers themselves thereby providing a unique picture of trends in job quality.The book is concerned both with wage and non-wage inequalities (focusing, in particular on skills, training, task discretion, work intensity, organizational participation, and job security), and how these inequalities relate to class, gender, contract status, unionisation, and type of employer. Amid rising wage inequality there has nevertheless been some improvement in the relative job quality experienced by women, part-time employees, and temporary workers. Yet the book reveals the remarkablepersistence of major inequalities in the working conditions of other categories of employee across periods of both economic boom and crisis.Beginning with a theoretical overview, before describing the main data series, this book examines how job quality differs between groups and across time.
