Dutchie and anyone else going to a Netjets interview.
Netjets is right. No matter what they tell you or put into your contract they will change it if they want. They have done it and will do it again.
It does not matter if it is in writting, it will changeif some one decide that they want you to work more than you agreed.
Netjets pilots in the US are discussing a strike. In europe this will not happen because the pilots are never all together and the company know this.
