Final answer:
The laissez-faire leadership style gives all power and authority to employees, characterized by a hands-off approach and allowing team members to manage themselves.
Step-by-step explanation:
The leadership style that delegates all authority and power to employees is called laissez-faire. A laissez-faire leader is one who adopts a hands-off approach, allowing team members to make their own decisions without much guidance or intervention. This style is characterized by a degree of autonomy granted to employees, which can result in high levels of creativity and motivation among highly capable individuals. It is important for situations requiring innovation or when team members are more knowledgeable in specialized areas. However, this approach can also lead to a lack of direction and cohesion if not managed properly.
