Hang on a second kids.
1/. If you have been out on the piss all night (cos no young pilot has EVER done that
)
Is it your employers fault you are hungover?
Should you report for duty secretly impaired?
If you do, is it then your employers fault when you spear into a hill with 9 bods behind you?
2/. You have been up all night shagging your boyfriend/girlfriend/blow-up doll (cos no young pilot has ever done that... probably).
Is it your employers fault that you are such an awesome swordsman?
Should you report for duty secretly impaired?
If you do, whose fault is it when you spear in?
Your fitness for work is YOUR responsibility and it doesn't matter by what mechanism you ended up shagged.
If your boss has been flogging you like a racehorse he is required to have systems in place that will limit the flogging you can receive at work. Your employer cannot, however, control or monitor your private life.
If you burn the candle at both ends you are morally obligated to remove yourself from a position in which you could kill other people through inattention.
If your lifestyle is impacting the career you worked so hard to earn, maybe you should ask Daddy to pay for a career in stockbroking instead.
