If you read the LOA, STV is voluntary - you can bid it. If the slots are not filled then they will be assigned. Even if most of the slots are filled by volunteers, is it worth giving this to the company (ie - what do we get for it)?
Also what extra RLA protections are we getting from the LOA that are not already in the CBA? It appears to me the only gains go to the company.
All-in-all this LOA is a give to the company for nothing in return!
My vote is NO
