Pleaseeeeeeeeee, by all means present the mowrey doh c n r's list to the company again so we can all move forward in a federal court of law.
When there is a ratified contract, you will be as free as anybody in this country to file a lawsuit, but it won't be until then and your legal challenge will be that it breached "Good Faith". It will have nothing to do with Nicalou. Pleeeeeeeeeeasssssssseeeeeeeeeeeeee educate yourself on that issue. Your union will not be hamstrung to defend itself next time around. Good luck proving the union acted outside of a "wide range of reasonableness" with the mountain of evidence and history that can be used to defend a longevity based integration. A "Wide Range" is exactly that and there is a reason that DFR suits are very unsuccessful. The West pilots drew a good judge but the law finally caught up to the case.
As stated before, after the precedent of this ruling, good luck with the huge retainer you will need to get any serious legal help next time.
