Despite their continuing importance to the UK economy and their employment of significant numbers of workers from a range of professions, the utilities have received scant attention from critical scholars of work. This neglect represents a missed opportunity to examine the impact of nearly twenty years of privatisation and marketisation on workers, their jobs and their unions. This thesis aims to make a contribution to knowledge here by investigating, contextualising and explaining changes in the labour processes of a privatised utility in the United Kingdom. The research is informed by oral history methods and techniques, rarely adopted in industrial sociology, and here used alongside labour process theory to reconstruct past experiences of work. Drawing on qualitative data sets, from in-depth interviews with a cohort of employees who worked continuously over three decades at the research site, British Gas’s Granton House, and on extensive company and trade union documentary evidence the research demonstrates how British Gas responded to restrictive regulation and the need to deliver shareholder value by transforming pre-existing forms of work organisation through introducing call centres. The call centre provided the opportunity for management to regain control over the labour process, intensify work and reduce costs. In doing so, the study identifies the principal drivers of organisational change, documents the process of change evaluates the impact on workers’ experience. Thus, as a corrective to much recent labour process theory the research offers both an ‘objective’ and ‘subjective’ account of change over an extended time. The contrast between workers’ experience of working in the clerical departments and in the call centre could not be starker. Almost every element of work from which workers derived satisfaction and purpose was abruptly dismantled. In their place workers had to endure the restrictive and controlling nature of call centre work. The relative absence of resistance to such a transformation is shown to be a consequence of failures in collective organisation, rather than the totalisation of managerial control, as the postmodernists and Foucauldians would have it.

Le travail des chefs d’établissement (ChE) a évolué au gré des politiques éducatives. Ces derniers deviennent des agents du changement ou managers dans des établissements autonomes soumis à l'obligation de résultats. En France en 2006, les ChE rencontrent de nouveaux défis avec les réseaux ambition réussite (RAR) au collège. Une situation inédite qui pose une question nouvelle aux ChE : comment piloter des équipes composites dans un collège en RAR ? Le parti pris dans cette thèse est celui de l’ergonomie de l’activité qui questionne un paradoxe : d’un côté, la focale est mise sur le développement du travail collectif dans les établissements et son impact sur les performances, d’un autre côté sont négligés l'organisation du travail à laquelle se livrent les cadres pédagogiques comme le travail d'organisation des professeurs pour faire vivre ces collectifs. Le but ici est de montrer l’importance du travail réel pour comprendre les conditions et difficultés des cadres pédagogiques pour organiser le travail des professeurs. / Headmasters' work has been changing with educational politicies. Headmasters are becoming agents for change or managers in schools wich are independent and under an obligation of results. In France in 2006, headmasters are challenged with the reform of Ambition success networks. An unprecedented situation that raises the question : how to manage heterogeneous teams ? This thesis uses the ergonomic approach to the activity in order to study a paradox : on the one hand, the focus is put on collective work and its impact on performance, on the other hand, the organisation of the work by headmasters and the work of organisation by teachers are ignored. The aim is to show the importance of actual work in order to understand conditions and difficulties of the work of organisation in wich headmasters are engaged.
