Today, I didn’t give a 110% at work. I estimate this would have cost about 300kgs of fuel.
I am an army of one.
That's the spirit!
Now if everyone did this on every flight imagine the costs?! Using above example, roughly $700 x number of flights per day (not known exactly by me), the costs must be near an extra $100,000 a day. Or $36,000,000 a year. Compare that to the amount you are saving by pissing everyone off with these contracts.
Easier to treat your staff well really.
