The reason the bonding process is possible is because there are those out there that would sign their scrotum away for 2 years for an IF or twin endorsement.
If someone was to refuse signing a bond then each company would deal with it differently I guess. I would never sign another one, not in a pink fit. I would be more than happy to verbally commit to a period of employment ,subject to being treated fairly and looked after by the company and in that case I would stand by my word.
You could find yourself working for a company that is nothing like what it seems and far from what you expected.
Remember when you are looking at it the grass is still green.
Blade root mentioned earlier in this thread that you should just read the riot act when you are presented with the basic award and he's dead right. That is probably easier to do in a small company than it is in a big one when there is others around you who don't.
Who do you think will be selected for a promotion when they need another twin pilot? Certainly won't be the bloke who says no when he's asked to work a day off.
Those that are prepared to go the extra mile would also be willing to sign a bond and they shouldn't have to.
