Organizations underperform, or fail, when members avoid partnering with managers—whether through subtle resistance, disagreement, protest, or walkout—to achieve common purpose. Managers should boost partnering not by affecting a pretense of leadership but through a nuanced balance of managerial authority and understanding of members’ points of view. The objective of this article is to sharpen attention on the concept of partnership with organization members and how it relates to some of the important previous literature. We also argue that some of the previous scholarly work contributes to misconceptions related to these concepts. Our work is forward-looking in that it is motivated by the dangerous societal and cultural differences evident in the world, differences that surround management’s decisions and that may induce an overuse of authority to quash disquiet. Using our experiences in both industry and academia, we argue that the crucial link between managers and members is leadership—not leadership thought of as directional and inspirational, but leadership as building a relationship toward common purpose through partnership. “Lead” and “leader” are sorely misused terms, and worse, substituting “leader” for “manager” is just plain wrong. We believe that managers become leaders only when followers agree to follow, not when the managers simply step forward energetically with direction. Managers are cheated by mistaken definitions. Reviewing past perspectives about what makes good leaders and managers, we rethink ways to enhance organizational harmony through a clearer understanding of managership, leadership, followership, and partnership. Only by thinking and acting as partners in common purpose can managers and members form the core of success in organizational endeavors.  相似文献

This conceptual article examines the relationship between marketing and sustainability through the dual lenses of anthropocentric and ecocentric epistemology. Using the current anthropocentric epistemology and its associated dominant social paradigm, corporate ecological sustainability in commercial practice and business school research and teaching is difficult to achieve. However, adopting an ecocentric epistemology enables the development of an alternative business and marketing approach that places equal importance on nature, the planet, and ecological sustainability as the source of human and other species’ well-being, as well as the source of all products and services. This article examines ecocentric, transformational business, and marketing strategies epistemologically, conceptually and practically and thereby proposes six ecocentric, transformational, strategic marketing universal premises as part of a vision of and solution to current global un-sustainability. Finally, this article outlines several opportunities for management practice and further research.  相似文献
