This book provides an account of the evolution of social security and employment policy and governance in Britain between 1973 and 2023. It explains how this remaking of policy and governance shaped, and was shaped by, the transformation of the labour market and power of claimants and workers. Advancing a class-centred explanation, the text situates contemporary working age active labour market policy as the contingent outcome of a long struggle over curtailment of labour autonomy and the challenges arising from policy ‘success’ for securing social cohesion, state legitimacy and better economic conditions for growth.This book provides an account of the evolution of social security and employment policy and governance in Britain between 1973 and 2023.
