I have found that sometimes the company makes an error with the cost index on the flightplan, as sometimes the flight time might be longer than the block. I try my best to fix this by adding the fuel and and going faster. So when they make an error with my roster, and dont give the days off required, I also try and help out by dailing #2.
If they didnt want you to take those sick days they would pay you for them at the end of the year.
Help them help us.
