Crew Rest, Fatigue, and a Colleague Who Should Not Fly
You are the senior cabin crew member on a two-sector day. Your colleague, a cabin crew member with eight years' service, arrives for the first sector looking pale and tired. She mentions she slept about three hours because of a family problem, and that she has taken an over-the-counter cold remedy containing a sedating antihistamine. She says she is fine to fly. The first sector is a short hop, then a two-hour turnaround, then a four-hour sector landing after midnight local time. The crew complement is at the minimum required for the aircraft type, so removing her would mean the flight cannot operate as scheduled.
1. What are the competing pressures here, and what is the correct professional judgement?
Read the worked answer
Competing pressures: operational pressure (minimum crew complement, schedule, passengers, cost of delay), loyalty to a colleague, her own wish to fly and not be seen as unreliable, and your duty to safety. The pressure that must not win is the operational one.
Correct judgement: she should not operate in this condition. Two factors combine: significant sleep loss (about three hours) and a sedating antihistamine, which impairs alertness and reaction time and is explicitly a concern for safety-critical duty. Fatigue is a known contributor to error, and a crew member who is impaired cannot perform emergency duties reliably. Minimum crew complement is a reason to find a replacement or delay, not a reason to fly with an impaired crew member.
Practical steps: raise it privately and without accusation, ask her to speak to the commander or the operator's medical/roster contact, document what she told you, and escalate to the commander if she insists on flying. Do not simply "keep an eye on her" as a substitute for the decision. If the flight is delayed or cancelled, that is a consequence of a safety decision, not a failure by you.
2. How would you handle the conversation with her, and what would you avoid saying?
Read the worked answer
Do: speak privately, early, and calmly. Frame it around safety and support, not discipline: "I'm concerned about you flying today, not about getting you into trouble." Ask open questions about how she is feeling and what she has taken. Explain the specific risk plainly: the sedating remedy plus three hours' sleep affects her ability to do her job in an emergency, and that is the standard, not whether she feels fine. Offer the routes available: speak to the commander, contact the operator's medical or roster team, or report unfit for duty. Reassure her about confidentiality and that fatigue reporting is a legitimate process, not a mark against her.
Avoid: discussing it in front of other crew or passengers; making it personal or moralising about her family problem; saying "you look terrible"; pressuring her either to fly or to go home; promising outcomes you cannot deliver; and using words like "I'll have to report you" as a threat. Also avoid the opposite failure of saying nothing because she is a friend or senior to you.
If she becomes defensive, do not argue in the cabin; escalate to the commander and let the formal process handle it.
3. The flight operates with her on board and she makes an error during the second sector. What does a just-culture view require of you?
Read the worked answer
A just-culture view separates the decision from the outcome and looks for system factors as well as individual ones.
Individual accountability: she chose to report for duty after taking a sedating medication and after very little sleep, and she told a colleague rather than declaring herself unfit. That is a legitimate matter for review, and she should be dealt with fairly and consistently with how others are treated.
System factors that must also be examined: was there pressure to fly because crew were at minimum complement? Was there a clear, trusted route to report unfit for duty without penalty? Did the operator's fatigue and medication guidance reach her? Did you, as senior crew, escalate properly, and did the commander act on the information? If the answer to any of these is no, the error is not hers alone.
What you do: report the occurrence factually, including what you knew, when, and what you did; do not conceal your own part or hers; support an investigation that looks at both the person and the system; and avoid a blame response that would teach the next crew member to hide fatigue. The aim is a safer operation, not a scapegoat, while still holding people accountable for deliberate choices.
