Les pratiques de gestion à haute performance et l'épuisement émotionnel
This thesis aims to explore the indirect effect of high-performance work practices on emotional exhaustion. Job resources (job control and supervisors social support) and job demands (psychological demands and work hours) are theorized as mediation mechanisms in this relationship. Job demands-resources theory (Demerouti et.al, 2001) in background of this work is enhanced by the addition of a group-level construct in the explanation of emotional exhaustion. Therefore, this study aims to test two antagonistic perspectives on the effect of high-performance work practices on occupational health. The data for this study is from the SALVEO study conducted between 2009 and 2012 by the Équipe de recherche sur le travail et la santé mentale (ERTSM). A total of 1,961 employees in 89 employee groups nested in 60 workplaces were surveyed on their perceived level of job control, supervisor social support, psychological demands, work hours and emotional exhaustion. The line managers were surveyed on the implementation of high-performance work practices. To test hypotheses, descriptive analysis, bivariate analysis, and multilevel path analysis were performed. Results suggest that job resources reduce emotional exhaustion whereas psychological demands increase it. The finding further reject the pluralist perspective and confirm the unitarist approach by arguing that some high-performance management practices such as compensation and participation in decision-making are associated with less emotional exhaustion by providing more job resources to individuals. Others like staffing are also associated with less emotional exhaustion by reducing jobs demands. Moreover, we did not find evidence that combination of high-performance management practices had more effect on individuals than individual practices. Results highlight the importance of continuing studies on the association between human resources management and occupational health.
