Aims & Objectives: The purpose is to study the process of space appropriation implemented by workers in an university , and how it relates to job satisfaction. There are three objectives : - Define the space appropriation process implemented by the employees, on an institutional level as well as on office level - Determine how this process can be related to job satisfaction by using two indicators, satisfaction at work and satisfaction with the workspace. - Show that space appropriation is a significant predictor of satisfaction at work . Context & background literature :Introduction Our industrialized societies are more and more frequently confronted with organizational problems due to the rise of new technologies and changes in work behavior. As a result, the workspace has become a central topic in environmental psychology (Fischer, Tarquinio et Vischer, 2004). Although there has been much research done on the process of workplace appropriation, we should note that there are only a few studies specifically concerning the link between space appropriation and workplace satisfaction (Paznik,1986 ; Monjaret,1996, 2002 Method of inquiry or argument: 136 French Board of Education((Education Nationale) employees working in the «central region» of France answered a three-part questionnaire : (i) items aimed at determining the sociodemographic and organizational variables, (ii) the spatial appropriation as indicated by the appropriation of institutional space and office space and, (iii) job satisfaction as indicated by satisfaction at work and satisfaction with the workspace. The questionnaire was sent by e-mail.Findings & Conclusions: Our research shows that the employees adapt their space on an institutional level as well as on an office level. Furthermore it underlines the differentiated impact of space appropriation on the indicators of satisfaction; in particular, it points out the predicting power of the indicators of space appropriation of workspace satisfaction.. These results must be confirmed and more closely analyzed in other complementary research in order to more precisely understand the processes of man’s adaptation at work. They do, however, show the interest for town planners and environmental social psychologists to create spaces and even encourage employees to establish an appropriation process of their institutional space and in particular, their office one.
