Do you mean this?
Except as otherwise provided in this Agreement, placement on the Polar Air Cargo Crewmembers System Seniority List shall govern all Crewmembers with respect to upgrade and downgrade, retention, furlough and recall in case of reduction in force, award of domicile vacancies and displacements from domiciles, and any other assignments or awards.
So "otherwise provided in this agreement" is just one paragraph down as well as 23 A 1 - correct?
You guys were sold a bill of goods by Dan Katz, who was the only person to really make out on this whole debacle. He tried to make this about scope and the Atlas flying while Polar Engineers were furloughed. Bloch turned it right back to the seniority issue, which is where it really belongs. Yet your CBA is pretty specific don't you think. PFEs furloughed shall be done in order with respect to all the other PFEs on the list. Your CBA gives the PFEs an opportunity to bid to FO once they get themselves qualified. The fact that many decided not to should not be a reason for a grievance.
