Well, that's life under Wakefield for ya'. I got SO frustrated trying to work Communications with "We can't tell them that yet", or "We can't come right out and say that", keep-it-close-to-the-vest tactics.
I'd bet you a c-note that ALPA legal was absolutely ready for this and had planned for it from the day the first announcement about Colgan was made.
You'll probably get a blast email that says something to the effect of "We had hoped the company would not attempt this but, with the Company's history, we were prepared for it and have filed a suit in ____ Superior Court to uphold our RIGHTS under the Scope provision that Pinnacle management signed."
After that you won't hear squat until it's over. POSSIBLY dates for hearings and such, but most likely not.
Sucks, I know...
