Leadership is a process of communication between a leader and individuals in which the behavior or attitude of the leader effectively directs individuals towards any goal . It is widely accepted that leadership creates a vital link between organizational effectiveness and the performance of people at the organizational level (Avolio, 1999; McGrath and MacMillan, 2000). The effectiveness of an organization depends on the leader having an effective leadership style in order to effectively achieve the objective of the organization; it is one of the main drivers of improving business performance. Researchers suggest that effective leadership behaviors can facilitate improved performance when organizations face problems (McGrath & MacMillan, 2000).
