I like how you took my response to a post having nothing to do with a disparity of outside hire wages vs. established wages from 4 YEARS AGO and turned it into the argument YOU wanted to have instead. But here we go....
You're acting as if you represent part timers as a whole. Many part timers are interested in the sick days, vacation days, medical, dental, vision and pension contributions the peak hire doesn't see. The union has to represent the workforce as a whole. Their actual goal is to get as many opportunities for part timers to move into full time jobs and eventually retire.
As to your assertion that the union only gives a sh#t about full timers, well, that's actually the goal. Getting as many part timers into and protecting good full time jobs. I, for one, seem to remember 15 days in 1997, where I as a full timer and 10 year UPSer walked a picket line when the union was fighting for part timers and asked all of us to support a strike. We did. So to your point of the union only caring about full timers, the longest strike in UPS history was over part timers getting more full time opportunities.
So that leaves us with you complaining that for a couple weeks a year, an outside hire gets a few bucks an hour more used to entice them to come to our little hellhole for a few weeks. You say you've been working at UPS for years. You can't be naive enough to believe you'd have it better without a union. Can you? You feel like UPS management will give you a fair deal without the union. C'mon. Or, you're suggesting that because you alone feel slighted, you shouldn't have to pay dues because you're not "cared for" and let the burden fall to everyone else. I personally feel that you're being short-sighted, turning this into a one issue gripe, only looking at this from your perspective and therefore missing the whole point of a union.
