Greening Organizations: The Roles of Leadership and Organizational Citizenship BehaviorsRobertson, JENNIFER 13 February 2014 (has links)
Climate change is a serious global issue that poses one of the greatest challenges facing human kind (Kazdin, 2009; Stern, 2011; Swim et al., 2011). Given that organizations are often cited as the largest contributors to climate change (Trudeau and Canada West Foundation, 2007), research needs to investigate how organizations can positively affect climate change. Accordingly, the purpose of this dissertation is to investigate how organizations can positively affect climate change through workplace pro-environmental behaviors. To this end, three studies were conducted. The first study investigated the influence of leaders’ environmentally-specific transformational leadership and their own workplace pro-environmental behaviors on employees’ workplace pro-environmental behaviors. The second study examined if environmentally-specific and general transformational leadership are empirically distinct but related, whether environmentally-specific transformational leadership evokes higher levels of workplace pro-environmental behaviors than general transformational leadership, and if so, examined through mediation why this is the case. The third and final study conceptualizes and defines workplace pro-environmental behaviors as a form of organizational citizenship behaviors that are targeted at benefiting the natural environment (OCBE), and subsequently, developed and refined a measure of OCBE and assessed the measure’s psychometric validity. This dissertation concludes with a general discussion and highlights areas for future research. / Thesis (Ph.D, Management) -- Queen's University, 2014-02-12 16:26:52.658

Lean management pilosophy and its impact on employee attitudes and perfomance : the critical role of first line supervisors.Roberts, Joanne January 2014 (has links)
Abstract : Using a quantitative research design and survey data from 83 supervisor - employee dyads working in North American facilities of a large multinational healthcare organization, this study explores the critical role of first line supervisors in a lean environment. Many organizations have adopted the Toyota Production System (TPS, also known as lean management or the Toyota Way) in an effort to improve organizational effectiveness. Implementation success has been surprisingly limited. The predominantly negative effects documented in the scientific literature are attributable to the introduction of lean as a series of tools and techniques for cost cutting. In environments that truly manage according to the TPS, all share the belief that the development and participation of all employees is essential to maintain competitiveness. Increased emphasis on teamwork and worker involvement in a lean environment places rising demands on the first - line supervisor. The supervisor role in a lean environment is considered critical and becomes one of encouraging more participation, and creating an environment of continuous improvement. Given that leadership is a complex construct, the current paper uses a multi - domain approach proposed by Graen and Uhl - Bien (1995) to study the effect of empowering leadership behaviours (leader domain), leader - member exchange (relational domain) and psychological empowerment (follower domain) on individual performance (measured as in - role performance and organizational citizenship behaviours) through the mediating variable of job involvement in the work setting. Findings indicate that the role of the first line supervisor in a lean environment is critical. The follower (psychological empowerment) and relational (leader - member exchange) domains of leadership are significant in predicting variations of job involvement in the work setting, and job involvement mediates the relationship between the relation domain variable of leader - member exchange and individual performance (organizational citizenship behaviours targeted at the individual). Empowering leadership behaviours are significantly related and directly related to in - role performance. Development of first line supervisors should emphasize building high quality relationships, facilitating employee psychological empowerment, and demonstrating empowering leadership behaviours in order to enhance involvement in a team setting and individual performance. // Résumé : En utilisant une méthode de recherche quantitative ainsi que les résultats de sondages auprès de 83 dyades superviseur-employé travaillant dans des établissements nord-américains d’une grande organisation multinationale du domaine de la santé, cette étude explore le rôle clé des superviseurs de premier niveau dans un environnement de production « lean ». Plusieurs organisations ont adopté le Système de production Toyota (SPT, aussi connu sous les vocables de « lean management » ou de « méthode Toyota ») dans le but d’améliorer l’efficacité organisationnelle. De façon surprenante, le succès de l’implantation de cette méthode de production s’est montré limité. L’effet négatif prédominant documenté dans la littérature scientifique est attribuable à l’introduction du « lean » comme une série d’outils et de techniques pour réduire les coûts. Dans les environnements véritablement gérés selon le SPT, on partage la croyance que le développement et la participation de tous les employés est essentielle pour maintenir la compétitivité. L’accent sur le travail d’équipe et sur l’implication des travailleurs dans un environnement « lean » place des attentes élevées sur les superviseurs de premier niveau. Le rôle du superviseur dans ce type d’environnement est considéré comme critique et consiste à encourager la participation et la création d’un environnement d’amélioration continue. Étant donné que le leadership est un construit complexe, la présente étude utilise une approche multi-domaines proposée par Graen and Uhl-Bien (1995) pour étudier l’effet des comportements de leadership habilitant (empowering leadership; domaine du leader), de l’échange leader-membre (leader-member exchange; domaine de la relation) et de l’habilitation psychologique (psychological empowerment; domaine de l’employé) sur la performance individuelle (performance dans le rôle et comportements de citoyenneté organisationnelle) via la variable médiatrice de l’implication au travail, et plus spécifiquement dans l’environnement de travail (job involvement in the work setting). Les résultats indiquent que le rôle du superviseur est crucial. Les domaines de leadership de l’employé (c.-à-d. l’habilitation psychologique) et de la relation (c.-à-d. l’échange leader-membre) sont significatifs lorsqu’il s’agit de prévoir les variations de l’implication au travail, et l’implication au travail agit comme médiateur entre les variables des domaines de leadership et la performance individuelle (comportements de citoyenneté organisationnelle). Le développement des superviseurs de premier niveau devrait mettre l’accent sur la formation de relations superviseur-supervisés de grande qualité et faciliter l’habilitation psychologique des employés afin d’encourager l’implication dans le travail d’équipe, et par le fait même, la performance individuelle.
