The reality is simply that 30% participation and results of 55/45% against don't exactly indicate a mandate.
Those results are good enough for a contract to be signed.
However, I'd be surprised if there were less than 50% participation and 60/40 opposed to a change. But the poll is biased in favor of age 65, so some of the results of the poll will be used to make a case for changing ALPA policy.
The phone poll is complete; what were the results from that?
