If merely complying with an employment contract is viewed as being behaviour detrimental to the company then surely, by their own definition, they're abusing it! Don't they realize how ridiculous,arrogant and 'threatening' that sounds. I've read several missives from the DFO recently regarding the company's stance on intimidation and have watched them apply severe intimidation over 26 years!!
It's a fascinating situation whereby they refuse to apply a black and white rostering system without the 'if,buts,maybe's,and 'under normal' circumstances' that would essentially remove the instability and crew discontent and yet remain unaware that it could so easily be fixed. The only people who are looking aggressive and behaving dishonourably in full view on the international stage are the folks managing this shambles. How on earth can you employ a group of new joiners..immediately renege on the employment promises..be sued in court and lose a large settlement..still be forced to employ them and wind up with employees that hate you from day one and still think you've done a great day's work...insane!
