Final answer:
The Least Preferred Behavior theory suggests implementing a task-oriented leadership style when an individual changes their behavior to please an authority figure or to avoid aversive consequences. This style prioritizes task completion over group cohesion and is suitable when there is perceived unanimity among the group.
Step-by-step explanation:
The Least Preferred Behavior theory states that a task-oriented leadership style should be implemented when an individual changes their behavior to please an authority figure or to avoid aversive consequences. In this style, the leader prioritizes completing tasks efficiently and effectively rather than promoting group cohesion. It is more likely to be used when there is perceived unanimity among the group. For example, if a manager needs to meet a strict deadline or achieve a specific goal, they may adopt a task-oriented leadership style to ensure the tasks are completed on time and according to the set guidelines.
