Which of the following is NOT a duty of a lifeguard?

A lifeguard's primary responsibilities include supervising swimmers, maintaining a safe environment, and administering medical assistance when needed. These duties are crucial for ensuring the safety and well-being of individuals in aquatic settings.

Planning team schedules, while important for the overall management of lifeguard services, typically falls under the administrative duties of supervisors or managerial staff rather than the lifeguard's direct responsibilities. Lifeguards focus primarily on active monitoring and immediate response to emergencies, rather than handling logistical or scheduling tasks, making it clear why this choice is not considered a direct duty of a lifeguard.
