What I'm saying Maximum, is that the life of an airline pilot is far removed from the issues which the Human Rights Act was created to protect.
My employer called to change my schedule recently; they are allowed to do this up to 8 days before the date.
This inconvenienced my wife ia little but when she began to moan I had to cut her short. I have chosen my employer and our relationship provides for our house, food, clothes, car, holidays. etc. whilst they earn a good deal more for my services than they pay me, but that's OK.
I often use the 'I'll call back in 10 minutes' line to buy time and find out whether I really want or need the extra time off or money for an extra duty, or to see if I can arrange alternative plans so as to be able to take the extra duty. I do like to help where I can.
The other side of the coin for the crewing staff is that it is ceaper to pay someone a higher rate for extra duties than it is to employ an extra crew member, and there is always someone who needs the extra money!
