Path Goal Theory views the manager's role as a guide to help employees choose the best path to reach their goals. It is based on Expectancy Theory and provides a cognitive approach to understanding motivation. According to the theory, leaders should engage in different leadership behaviors depending on the situation to ensure employees' goals are aligned with organizational goals and provide them with the means to reach both personal and organizational goals. Directive leadership tells employees what to do, while supportive leadership shows concern for employees. Participative leadership encourages employee participation in decisions, and achievement-oriented leadership sets challenging goals and drives performance improvement. The most effective leadership style depends on factors like an employee's locus of control and the demands of the situation.
