For the record, I'm a part-timer with almost a decade in under my belt and make half the hourly rate of a package driver.
Out of 240,000 bargaining unit members working at UPS, only 180,000 were eligible to vote. That's 60,000 scabs, most of which are part-time. Union density is always higher in the driver ranks because of the constant threat of being fired for the most miniscule infraction. There are definitely more 22.3 combo scabs than drivers, but that's a separate issue and probably not statistically relevant.
Out of those 180,000 eligible voters only 64,518 returned ballots. While there were some reported ballot irregularities in several locals, that's roughly 36% of eligible voters being counted. 115,482 eligible Teamster members employed by UPS - many of them PT - did not return a prepaid return envelope with their ballot that required them to make up to a maximum of 3 marks to cast their vote.
While those are hard numbers, let me throw some anecdotal evidence at you: At my local's monthly membership meetings, there are roughly 6-8 part-timers (including myself) that regularly attend. While turnout is usually pretty low, there are probably five times that number of full-timers that attend. Simply put: The majority of part-timers do not participate in contract ratifications, officer elections, or union meetings.
A number of drivers on BrownCafe have admitted they would be more than willing to forgo chunks of their general wage increases in order to increase pay for part-timers. The majority, however, probably would prefer not to do so and, as a result, the PT work force essentially subsidizes the higher wage rates set for FT drivers because a contract favoring PT employees would have a good shot at being voted down.
