House and Mitchell’s (1974) discussion of path-goal theory suggests that leader effectiveness will be a function of the degree to which they can successfully shift back-and forth among different leader behaviors (e.g., supportive, directive, participative, and achievement-oriented). Fiedler (1974), on the other hand, suggests that it is difficult for leaders to make these shifts because of the powerful role played by their task or relationship-oriented need hierarchy. Thus, he calls for task re-engineering. Discuss these two competing perspectives. Argue how and why each perspective might be true.
