As a professional, is it not your responsibility to deal with the conditions and recognize issues such as fatique? This is the same for any high risk profession.
Look what they do to the train drivers in accidents where fatique was blamed, or truck drivers? Why is it that pilots feel they are exempt from punishment?
Does anyone assume that the pax expect a disaster because the driver has to commute or works too many hors and is tired? What about the other drivers sitting on the ground, are they responsible for being on the taxiway the AC was trying to land on?
If you cannot handle the job, then move on. If you dont move on, you should be removed.
