How can a leader's style affect a follower's motivation?

The path-goal approach is based on expectancy theory,"which suggests that subordinates will be motivated if they think they are capable of performing their work,if they believe their efforts will result in a certain outcome,and if they believe that the payoffs for doing their work are worthwhile." Leaders motivate by making subordinates' paths to their goals clear and their work conditions more satisfying.This involves choosing the leader behaviors that best fit subordinate needs (affiliation,etc.)and task characteristics (formal authority,group norms,etc.).
