its just denial of the problem until theres a fatal accident, then there will be a collective response of 'shock horror, how could the airlines let this happen', completely ignoring the fact that the EU and the local legislators are allowing and promoting working practises that will inevitably lead to the eventual accident.
There is no solution, pilots have allowed themselves to be 'raced to the bottom' and have demonstrated that they will prostitute themselves in any way to get on the greasy pole. Once there, they are intimidated by management to always go just that extra inch to save money and 'get the job done'.
We should be grateful that we work in the EU, at least we where a figleave of respectability and pay slightly more than lipservice to safety.
As to fatigue, just go sick when it all becomes too much. No-one, but yourself, will be hurt if you hit a tree at 4 in the morning after your 3rd late finish. Obviously, do not state fatigue as your reason for being sick, something more inventive will be required.
You are not alone, there are thousands of us staggering from one day to the next like walking zombies. Invest well and retire early is the only advice I have!
