Influence de la culture organisationnelle et du type de leadership sur la satisfaction au travail des infirmières soignantes

La moyenne pancanadienne des infirmières qui quittent leur emploi dans la première année d’embauche est de 19,9% (O’Brien-Pallas, 2010). Ce taux représente un coût important puisqu’on estime que l’embauche d’une nouvelle infirmière engendre des frais de formation de l’ordre de 30 000$ (Hayes, 2007). Le présent mémoire repose sur l’idée que le leadership des infirmières chefs et la nature de leurs interventions de gestion jouent un rôle important dans la rétention des infirmières sur les unités ce qui, à son tour, contribue à l’amélioration et au maintien d’un environnement de travail sain qui favorise l’adaptation aux changements organisationnels et opérationnels (Cummings, 2005). Selon une perspective environnementale d’analyse des systèmes organisationnels, cette situation implique que le bon fonctionnement de l’établissement de santé dépend de la capacité à « acquérir et maintenir les ressources », (Pfeffer, 2003 p.2) incluant les ressources humaines. L’objectif de ce mémoire est d’analyser l’influence de la culture organisationnelle et du type de leadership des infirmières chefs sur deux variables soit l’intention de quitter le poste actuel et la qualité perçue du milieu des infirmières soignantes. Cette étude quantitative s’appuie sur un devis corrélationnel. Afin d’assurer la représentativité, un échantillonnage probabiliste a été utilisé. Le biostatisticien de l’Ordre des Infirmières et Infirmiers du Québec (OIIQ) a fourni les noms et coordonnées de 1000 infirmières qui travaillent sur les unités de soins des quatre hôpitaux ciblés par l’étude. L’analyse des données a permis d’identifier quatre relations causales. Une relation a ainsi été établie entre la culture organisationnelle et le type de leadership utilisé. Ensuite une relation a été établie entre la culture organisationnelle et la qualité perçue du milieu. La relation suivante est entre le type de leadership utilisé et la qualité perçue du milieu par les infirmières soignantes. Finalement, l’effet médiateur du leadership résonnant entre la culture organisationnelle et la qualité perçue du milieu a été démontré. Des suggestions d’améliorations aux niveaux organisationnel et académiques ainsi que des recommandations au niveau de la gestion et de la pratique infirmière découlent de l’analyse des données. The national average of nurses leaving their job in the first year of employment is 19,9% (O’Brien-Pallas, 2010). Those changes represent an important training cost as it is estimated that hiring and orienting a nurse on a unit costs 30 000$ (Hayes, 2007). This thesis is based on the idea that nurse managers’ leadership style and their management interventions are playing an important role in nurse retention. In turn, retention contributes in maintaining and improving a healthy work environment where those conditions facilitate organisational and operational adaptation (Cummings, 2005). From an environmental perspective for analysing organisational systems, this implies that good functioning of health care establishment depends on its capacity of “acquiring and maintaining resources” (Pfeffer, 2003 p.2), which includes human resources. The goal of the present master’s thesis is to analyse the influence of organisational culture and nurse managers’ leadership style on bedside nurses’ intent to quit actual position and their perceived environment quality. This quantitative study is based on a correlational design. To ensure representativeness, a probability sampling was used. Biostatistician of the College of Nurses of Quebec (OIIQ) provided the names and addresses of 1,000 nurses working on the wards of four hospitals targeted by the study. Four major relations were detected after data analysis. The first relation was established between organisational culture and the type of leadership used by nurse managers. Second relation was established between organisational culture and its impact on bedside nurses’ perceived environment quality. Third relation was established between the type of leadership used by nurse managers and its impact on bedside nurses’ perceived environment quality. Finally, it was demonstrated that resonant leadership acts as a mediator between organisational culture and perceived environment quality. Suggestions for improvements regarding organizational and academic levels and recommendations at the management and nursing practice levels arising from the analysis.
