According to the behavioral approach to leadership, effectiveness is not determined by the personal qualities of the leader, but rather by his way of behaving towards his subordinates. Behavioral theory assumes that the leader affects the actions of his or her employees and then manipulates the workplace. Thus, we can highlight the similarity between the trait and behavioral approaches: they both focus only on the leader, while completely ignoring their colleagues. Both theories state that the leader must operate according to what is acceptable to him and must behave in the way that makes sense to him and create a comfortable work environment only for himself (Miner, 2015). According to these concepts, employees are expected to adapt to the personal qualities of their manager and his behavioral approach. This creates a big disadvantage for theories of traits and behavior. None of them are able to identify the logical relationship between the leader's personal qualities and behavior on the one hand, and effectiveness on the other (Miner, 2015). However, together they create a basis for the development of a more effective situational approach.
