Even with punitive sickness program in play....CAD should get their ass kicked for permitting it.
This is a 41 year old person....who knew they were sick and flew.....with a highly contagious and damn hard bug to quarantine ....should have the book thrown at them. Cathay FOP dept should be hauled over the coals. Even if immunised we could have sat in that seat picked up the bug and brought him home to our children. This person showed a complete lack of thought....and we have him employed flying pax....like you just demonstrated max incompetence.
If he had to be hospitalized he knew he was too sick to fly.....no grace from this pilot.....just shame and sack. The race to the bottom in pilot quality .....
