What leadership style is characterized by the leader actively making all decisions and having complete control over the group?

The leadership style characterized by the leader actively making all decisions and having complete control over the group is authoritarian leadership. In this style, the leader maintains strict control and minimal input from group members, making unilateral decisions and expecting obedience. This approach can lead to efficient decision-making in certain situations, particularly where quick responses are necessary or where the leader has expertise that exceeds that of the group members.

This leadership style contrasts with others such as democratic or participative styles, where input and consensus from group members play a crucial role in decision-making, fostering a collaborative environment. The laissez-faire style also differs significantly, as it allows group members much more autonomy and freedom in their work, with minimal intervention from the leader.
