I don't see that happening today, either. I saw some of it "trying" to happen around the time I started 3 years ago, but in all the cases I saw, the captain won the disagreement without reprimand. It's really hard to argue with safety, and any captain worth his or her salt will do what's right, regardless of what the company says. (Within reason, of course.) After all, that's your job as a captain. If you're taking flights you don't feel are safe, that's not very "in command" now, is it?
