Hellenic aviator,
You have hit the nail on the head. I have been almost told to go into discretion on several occasions, not been give a day room on a 7hr split and been told that I am not fatigued when I felt sick with tiredness and clearly was.
I fully realise that there are commercial pressures, but we are not machines and as has been mentioned - always the butt of the blame culture when it goes tits-up.
