Let's hope you never get taken to hospital in the early hours where you might need life-saving treatment from a doctor who has been working for 24 hours.
No need to get offended.
To use your analogy: A few years ago I had a hospital operation which required me to stay in hospital for nearly three weeks. It was obvious that medical cover was poorer at weekends with more junior staff than weekdays when more senior staff were on duty. In fact this problem is all over the news now.
The same applies to operating aircraft.
