I don't quite think that asking the reason you are refusing a extension is intimidation. All I have ever had is a simple phone call asking why. Once a follow up from the CP's office. Paid every time.

File the reroute grievance!! Even if you don't understand it, file it.

Really. I'm going to accept the assumption that the people working for the "company" are smart, intelligent people. What reasons other than fatigue or reaching a point where one is unfit for duty would there be for not extending a 12+ hour duty day?

that is some serious knowledge.

Ehhhh.....just a marginal ability to read the PWA.

Most guys don't even do that. They just assume it says something because they were told it does by someone else. Same with TAs, memos, and bulletins.

"We didn't think they'd do that".........

It's actually printed somewhere?

The problem with reading the contract is that you can find a paragraph describing exactly your situation, but it turns out to have been superseded by a LOA/MOU, or an exception, etc. Agree, there's a lot of bad gouge spouted by the sea lawyers. It's complicated.

Even with a LOA/MOU at least one can find a written reference. It is the "past practices" or "accepted interpretation" which aren't written that torque me, especially when the language of the PWA is unambiguous.
