This paper applies the GLOBE Society Practices framework and cultural assessment tools to analyze organizational culture across Greek, Iranian, Singaporean, and German employees. It examines how national cultural dimensions—including power distance, uncertainty avoidance, and communication preferences—shape leadership effectiveness, workplace productivity, and broader organizational culture. The paper demonstrates that transformational and transactional leadership approaches, when culturally adapted, can bridge cross-cultural differences. Key findings emphasize that effective multicultural leadership requires understanding distinct cultural values and communication styles to achieve organizational goals and employee engagement in diverse settings.
Studies have shown time and again that the effectiveness of organizational leadership is directly associated with higher employee morale, productivity, and profitability, as well as reduced employee turnover (Daniel & Cieslewicz, 2012). Indeed, Russette and Scully (2008) emphasize that "Successful leadership behavior of today's more culturally diverse workforce is one of the most important challenges organizations face" (p. 47). Given the increased diversity of many organizations due to globalization and innovations in communication, it is not surprising that there is also growing interest in identifying cross-cultural differences and how they affect the effectiveness of leadership.
The Global Leadership and Organizational Behavior Effectiveness (GLOBE) Study identified nine cultural dimensions that characterize societies and organizations: power distance, uncertainty avoidance, humane orientation, institutional collectivism, in-group collectivism, assertiveness, gender egalitarianism, future orientation, and performance orientation. The first six cultural dimensions were originally described by Hofstede in his seminal book, Culture's Consequences: International Differences in Work Related Values (1980).
One of the major findings to emerge from the GLOBE Study of 62 Societies (2004) was that the effectiveness of leaders is contextual because of the overarching organizational and societal norms, beliefs, and values of the followers involved (Hoppe, 2005). In addition, Russette and Scully (2008) report that "The general findings of GLOBE were that cultural dimensions that influence leaders do exist and that these dimensions can be identified and measured" (p. 48). Subsequent studies by other researchers have provided support for the GLOBE study findings, and there is a growing consensus that leaders must recognize differences in culture in order to be effective (Russette & Scully, 2008). In cross-cultural settings, it is therefore vitally important to understand these fundamental and powerful cultural differences to provide effective leadership. A number of cultural assessment tools are available to facilitate this process, including the GLOBE Study, Geert Hofstede's increasingly expanded cultural dimensions, and the World Bank Worldwide Governance Indicators (Daniel & Cieslewicz, 2012).
When applied to individuals from Germany, Greece, Iran, and Singapore, these cultural assessment tools reveal significant cross-cultural similarities and differences that would have important implications for leadership practice. For instance, all four of these societies score similarly on the GLOBE Study's assertiveness and power-distance indexes, but they differ widely on other indexes, especially uncertainty avoidance. Likewise, none of these four countries fall within the same country clusters of similar cultures developed by the GLOBE Study, which indicate that Germany falls within the Germanic cluster, Greece within the Eastern European cluster, Iran within the Southeast Asian cluster, and Singapore within the Confucian cluster (Hoppe, 2005).
Although it would be impractical to use a completely different leadership style for each individual in this multicultural group, it would be both possible and important to take into account the most salient factors that influence leadership effectiveness. This process would include making a personal inventory of values and formulating a personal leadership style that would be most effective most of the time. In this regard, Russette and Scully (2008) note that "A leader's personal values along with those of the followers influence the leader, and these values can differ by culture" (p. 48).
A personal inventory of values and past experience with leadership in different settings indicates that a transformational and/or transactional leadership style would be most effective in this situation. According to Sosik (1998), "Leadership scholars have identified transformational leaders as highly effective in enhancing group creativity. Transformational leaders use intellectual stimulation, promote consideration of different viewpoints, and inspire collective action to promote group creativity" (p. 112). It is important to note, however, that "Even transformational and transactional tactics used by leaders may vary in their levels of success in differing cultures" (Russette & Scully, 2008, p. 48).
Despite these constraints to leadership effectiveness, it is possible to provide highly effective leadership using transformational leadership if the individual employee's culture is taken into account to forge solid leader-follower relationships. In this regard, Jung and Yammarino (2001) point out that "The nature of the relationships that transformational leaders establish with their followers is oftentimes based on emotional engagement and personal liking" (p. 3). In sum, a transformational and/or transactional leadership style would likely produce the most effective leadership for this cross-cultural group.
Today, Germany is characterized by high levels of co-determination rights that must be considered by management (Hofstede, 2015). According to Hofstede, for German employees, "A direct and participative communication and meeting style is common, control is disliked and leadership is challenged to show expertise and best accepted when it's based on it" (2015). By contrast, Greek employees are accustomed to "one boss who takes complete responsibility" and take enormous pride in their cultural heritage (Hofstede, 2015). In addition, status symbols of power are highly valued by Greek employees to convey the importance of their social position and the need for respect (Hofstede, 2015). Moreover, Greek employees like to socialize, tend to place a high value on rules and regulations, and require some time to develop trust in business relationships (Hofstede, 2015).
Conversely, in Iranian culture, Hofstede advises that "subordinates expect to be told what to do and the ideal boss is a benevolent autocrat" (2015). Likewise, employees from Singapore place a high value on rules and regulations and are accustomed to receiving orders in the workplace (Hofstede, 2015). In addition, Hofstede advises that for Singaporean employees, "Control is expected and attitude towards managers is formal. Communication is indirect and the information flow is selective" (2015). Beyond these similarities and differences, employees from Singapore prefer to avoid conflicts in the workplace but place a high value on hard work and professional success (Hofstede, 2015).
Consequently, the social culture of this diverse group of employees will have a significant impact on what type of communication style is used by their leader. For instance, Silverthorne (2005) reports that "Communication effectiveness is influenced by the fit between the national and organizational cultures and by the cultural diversity of the employees. Communication obstacles will be experienced when national-cultural inconsistencies exist in communication strategies" (p. 217). Given the significant differences in communication preferences among this group of four employees, it would be essential to employ the communication style that is most effective for each of these discrete cultural groups.
"Bidirectional influence between team diversity and org culture"
The research was consistent in showing that national culture has a major impact on the effectiveness of leadership and that those leaders who take cross-cultural differences into account are more effective than those who do not. As workplaces continue to become more culturally diverse, these are timely and important issues for organizational performance, productivity, and profitability. In the final analysis, it is reasonable to conclude that in order to be an effective leader in a diverse cultural setting, it is necessary to fully understand the background and values of different cultures in order to provide the type of leadership that will be most effective in achieving organizational goals.
