Great News!
Great news and not shocking . . .
DL was non-union before the merger so you can count on that side staying status-quo and the NWA unions were an absolute waste of skin . . you can count on at least 50% of ex-NW voting them out (or choosing no union).
Not a statement on unions in general; but, simply my experience having been a dual union member at NW. I have worked for two non-union carriers (current as well) and two union carriers. The largest difference are that I experienced 3 strikes at union carriers which accomplished absolutely nothing.
I will take non-union ANY DAY.
