My read of the MOU and the SLI process it puts into place is that the NIC is dead. If I really thought otherwise, I would not vote for it regardless of anything else in it!
Will a seniority based integration with the APA transpire in the JCBA negotiation/arbitration going forward? Who knows, more than likely some hybrid agreement combining DOH, longevity, relative position, size ratios, equipment ratios, fences, freezes.....ect, ect, ect, will coalesce. Nobody will get everything they want, the "snapshot" will be taken in the present and it won't include the NIC.
