First Bag
Your point about 25 minute turn rounds is? I would like to see you turn a full B737 800 round with 185 bags off then another 185 on.
When your management signed the contract it was, no doubt, on the basis that they accepted the terms and conditions and obviously believed that the staff were capable of turning a full 737 800 round in 25 minutes. If you now feel that you, and your colleagues, can't manage that, perhaps you should take it up with your management and ask for more staff.
The attitude of the Servisair staff, thats laughable, take a look at the attitude of some of your captains and you will see that they are a lot worse or you that blinkered or got your head so far up the captains bum you dont notice?
The Captain has responsibility to ensure that the aircraft departs on schedule: he / she has every right to use his / her best efforts to make it work. If that entails pushing you to stick to agreed protocols and SOPS it can hardly be described as "attitude"!
