The advantage of transactional leadership is that it clearly defines the roles and expectations from the leader and the followers. The style also ensures that the culture within an organization is maintained, with the rules strictly followed as well as the behavioral norms. On the other hand, the transactional leadership style means that failure to deliver the expected output can result in consequences like reduction of pay, absence of bonuses, or--the worse: dismissal. Simply put, this leadership style is a very direct, in-your-face approach, with the leader expecting results from his followers who in turn must deliver unless they want to suffer the consequences.
