Final answer:
This scenario is an example of empowerment, where the agent-in-charge at the gate has the authority to decide whether to give out a 'free ticket' when a flight is overbooked.
Step-by-step explanation:
This scenario is an example of empowerment. Empowerment refers to giving decision-making authority and responsibility to individuals lower down in the organizational hierarchy. In this case, the agent-in-charge at the gate has the authority to decide whether to give out a 'free ticket' when a flight is overbooked. This decision-making power empowers the agent to make a discretionary call based on the circumstances and the needs of the passengers.
