This paper investigates the relationship between defensive communication in performance appraisal settings by considering the mediating effect of leader–member exchange relationships. In a study of employees of a US federal fire department, defensive communication was associated with lower quality leader–member exchange relationships, which in turn was related to burnout. We discuss the implications of these findings, particularly as they apply to organizations and their employees, as well as limitations and directions for future research. 相似文献

ABSTRACT The business world has been using corporate branding and relationship marketing to build customer loyalty and satisfaction. In recent decades, individuals have applied the tenets of branding to themselves to create the idea of personal branding—marketing yourself as your own brand. By thinking in terms of personal branding and relationship marketing, distance education librarians can more effectively reach out to remote students and build long term relationships that are beneficial to both students and librarians.
