“However, there was a disagreement between him and his managers about his conduct which led to the tribunal proceedings."
"about his conduct" Well that clearly means, according to the judgment, the named managers at Thomas Cook believe that refusing to fly due to a dangerous level of fatigue and putting the lives of passengers and crew at risk, and actually explaining that directly to the company, is "conduct" not becoming of a Thomas Cook Pilot. " at no point was Captain Simkins expected to fly while fatigued." . So apart from playing the spineless, passing the buck "oh I'm sick" card or, with criminal negligence, agreed to fly what EXACTLY should he have done? lie?
The comment about his "conduct" appears to have spectaculaly backfired.
