So today I asked my SUP (full-time) one if I could switch from loader to unloader. He didn't give me a yes or no for a while after explaining in many ways to persuade me not to switch. He said if everyone came up to me and ask that I'd have to move everybody. I simply said "I'm not everybody" So he blah blah ranted on about excuses which I thought they were about how come he couldn't or can't. Then he said "Its possible I can, then no, then some lecture" Then he asked my reasons and I simply stated some reasons and then said honestly my reasons don't matter. After 25 minutes of him trying to figure out what to say I completely wanted a yes or a no. Then he says "he" invested in 1,000$ to train me and to pay this person to train me which he didn't UPS did *I thought in my mind* I simply stated I believe loading is not for me, and I'd like to try the unload and experience a different department of UPS. I thought I had the right to do such a thing which I was told by employees I could inside my HUB.
