Actually, I thought the main thrust of the article was that you needn't (and shouldn't) go ballistic over disagreement that you have the means to win anyway. Once the dispatcher/scheduler/whatever group realizes you're not going to be pushed into anything you aren't willing to do, you won't have nearly the problems you'd have if they thought you'd negotiate...and arguing IS negotiating. Anybody that's been around long should already know that, but the article did a good job of pointing it out anyway.
