This will also help to identify which style of leadership may be more helpful in the current organizational context, where global competition is intensive.This section will examine the impact of leadership styles specifically upon team communication and interaction. It will also look into differences in managerial styles within different organizational contexts and the corresponding impact upon employee perceptions.An attempt will be made in this study to conduct a thorough examination of the literature review, in order to determine what previous authors have concluded as a result of quantitative studies that have examined the issue of leadership. In view of the studies that are examined below, the importance of the research question posed in this study is further highlighted. In a rapidly changing, global environment that is also intensely competitive, the importance of relevant, clear, and effective leadership becomes vital in ensuring organizational success.The article by Tatum et al (2003) is useful in comparing transformational and transactional leaders. It points out the differences between these leaders in their decision making styles and organizational justice patterns. Transformational leaders adopt a comprehensive approach in their decision making and tend to focus on the achievement of social justice in the workplace. Transactional leaders, on the other hand, adopt a more structured approach towards organizational justice and in their decision making, they tend to favor limited options and few alternatives.A study conducted by Aarons (2006) developed the concept of transformational and transactional leadership further in the context of mental health providers’ attitudes towards adopting the evidence-based practice.
