Leadership remains a cornerstone of organizational success, particularly within multinational corporations (MNCs) that operate in diverse and complex environments. Effective leadership styles and strategies are crucial for enhancing employee motivation and improving organizational productivity. This paper explores various leadership theories, including transformational, transactional, servant, and situational leadership, to examine their applicability in motivating employees within MNCs. Additionally, the paper highlights the role of cross-cultural leadership, communication, emotional intelligence, and strategic human resource management in driving organizational outcomes. Through a comparative analysis of previous empirical studies, the paper underscores that no single leadership style is universally effective. Instead, adaptable, culturally sensitive, and employee-centered leadership approaches yield sustainable improvements in motivation, innovation, and productivity. The discussion also considers the challenges of globalization, digital transformation, and remote working, offering practical strategies for leaders in MNCs to build resilient, motivated, and high-performing teams.The integration of diverse markets, cultures, and technological systems has heightened the need for leaders who can adapt to rapid changes while motivating employees across geographies. Leadership, once understood merely as a positional authority or the ability to direct teams, has evolved into a multidimensional construct encompassing vision, strategy, communication, and the capacity to inspire. Leadership styles and strategies have direct implications for employee motivation, which in turn, influences organizational productivity and competitive advantage.
