If a supervisor notices a crew member skipped routine maintenance, what should the supervisor do first?

The appropriate first action for a supervisor who notices a crew member skipping routine maintenance is to question the worker immediately. This approach emphasizes the importance of direct communication and accountability in the workplace. By addressing the issue right away, the supervisor can gather information about the reason for the oversight, clarify expectations regarding maintenance procedures, and ensure that the crew member understands the importance of their role in the upkeep of equipment and systems.

Immediate questioning allows for a constructive conversation, where the supervisor can provide guidance and support. It also reinforces the supervisor's role in maintaining safety and operational integrity within the sewage treatment facility. Engaging the worker directly fosters a culture of open communication, encourages responsibility, and helps prevent future oversights, thereby maintaining a high standard of operation.

Other options, such as assigning another worker to perform the skipped maintenance or monitoring the worker closely in the future, may not address the root cause of the issue or encourage accountability. Bringing it up later when a favor is asked could diminish the severity of the infraction and lead to misunderstandings in expectations and responsibilities. Therefore, immediate questioning is the most effective approach to address and rectify the situation promptly.
