I'm for DOH as long as that's the date they're hired to be IPA pilots (i.e. the date they come to or come back to the union). As far as I'm concerned, taking them from their supervisor position to a line pilot position is no different than taking them from an office job in Atlanta or a flying job at United wrt DOH. Is there any precident for a box-handler or package car driver getting hired as a line guy? Did they keep their original UPS hire date (serious question)?
Another thing to consider: the last time this was put to a vote (and failed), the bottom 200 guys or so were inelgible to vote because they were on probation. I would think you can add another 200 'no' votes next time.
