Long time lurker here and finally registered. Started at UPS about three weeks ago. Its been going pretty well so far. Im currently a preloader in a center. I've had a few misloads over the past weeks and have zeroed out 3 times. Last Friday I had five Package cars and ten misloads. Monday we were slow and I had three trucks with no misloads. Monday another trainee also started working a few trucks up from me loading with a pt supervisor. Tuesday I got to work five minutes late and I hadn't received any Packages yet but the trainee and pt sup were working on my trucks. I was told to go home for the day. Wednesday I came back to work and was told to go back home again and the pt sup gave me his number to call him on thursday prior to coming in. Thinking this may be the beginning of the end . Basically just want to know if I'm screwed. Should I start looking for another job? I've had a hard times somedays but nearly everyday I get done I help other loaders finish up. Know that might not mean much but I don't slack when I startup. Any advice or suggestions would be greatly appreciated.
