Final answer:
The most suitable leadership style for Axel, as the new supervisor of non-routine, experienced, and confident employees, is likely a supportive or participative style aligned with Theory Y, supporting autonomy and involvement in decision-making, as recommended by the path-goal theory.
Step-by-step explanation:
According to path-goal theory, the leadership style that would be most appropriate for Axel, as a new supervisor of highly experienced and confident employees working in non-routine jobs, would likely be a supportive or participative leadership style. Considering that these employees show high competence and confidence, they do not require a leader who provides extensive structure or close oversight. In the context of McGregor's Theory Y, which assumes that workers seek to work hard and productively, and driven by internal satisfaction, a leadership approach that facilitates involvement in decision-making and values autonomy would be effective. Axel should focus on being a facilitator and enabler, providing support and resources as needed, and seeking input from the team. According to transformational leadership style, being inspirational and considering the individual's needs can further enhance the motivation and productivity of such employees.
