I agree.Will and arbitrator undo what another arbitrator did?
Don't think so.
It seems like no one has considered the possibility that a new arbitrator might not care what list USAPA submits. Arbitrators don't have to use either side's seniority solution. It's not about splitting the baby. They can discard both sides and come up with something THEY think is fair given the circumstances. As long as they adhere to the law, and there is no corruption involved.
So riddle me this... Let's say USAPA submits a DOH list, and APA submits their list. Not wanting to undo what another arbitrator already did, what's to stop him from FIRST reordering the USAPA list as an exact mirror image of the Nicolau award? He cites the same reasons as arbitrator Nicolau did, and the previous arbitration. Then takes that reshuffled list that is no longer called the Nicolau award, and inserts it into his solution for the current merger, using ratios, fleet, seat, career expectations, widebody aircraft, projected attrition, and even some LOS adjustments.
There is absolutely nothing stopping an arbitrator from doing something like this. In the DL/NW merger the arbitrator rejected both sides solutions, and came up with his own. It ended up being closer to the DL suggested method, but used different assumptions.
There is just no way to predict what will happen in arbitration. But common sense will prevail. And IMO common sense dictates that an arbitrator will be reluctant to completely ignore a previous arbitration award by one of his peers. There is simply no precedent for it. The union can ask for and present whatever it wants to. But the arbitrator holds all the power.
