As far as the vote, hard to say. But there's the talk of the "sabotage" to the retirement number by certain members of the IPA. I wasn't here, don't know, doesn't matter.
I'm not sure the voters are the ones who prevented a better retirement, or the faction listed above. Personally I would have voted for a better retirement. I'm biased though, I couldn't get to UPS until a family member retired.
