I don't think $15 is greedy at all, all things considered. If you adjust for inflation, the $8/hr or so PTers made back in the 80s is higher than what even I proposed, and in my opinion $20/hr is closer to what we deserve for the work we do
and the bull
we put up with every day.
But more than that, the union should be setting the wage standard, not the government. So when minimum wage surpasses whatever hourly rate the Teamsters manage to negotiate, that's just embarassing. $12/hr will be less than my state's minimum wage by the time the next contract ends. And you better believe that if the minimum wage is higher than the contractual rate, the difference will be subtracted from raises...just like it is now.
And for what it's worth, I don't think UPS could staff my building for $12/hr if that was the new starting rate tomorrow any more than they can do so now for $10.20/$11.00.
In exchange for the higher starting rate, I'm willing to see progression extended by one or two years and the skilled pay raise eliminated, for reasons I already went over. I don't have as big a problem with progression as I do with the skilled pay being used for favoritism.
