So I recently started at UPS as a loader for the big semi-trailers. It's a rough job, but I like it and the workout that comes with it. Everybody has said my walls are decent for the most part, but I need to work on my speed and maintain the quality of the walls I have. Last I checked, I'm getting roughly 150-200 packages scanned/loaded per hour and it is my second day of actual work at UPS. I started working last Monday, then they didn't let me work on Tuesday, then I worked a full day on Wednesday, then they sent me home after an hour today. However, it's hard to work on my speed while still maintaining the quality of the loads if I keep getting sent home after a short period of time. I'm not sure why they keep sending me home early, especially today- as they said they were extremely understaffed and I needed to pick up the pace. Which I did, and I was busting my ass sweating trying to build good walls at a decent pace. About 30-45 minutes after my supervisor told me they were understaffed and I needed to pick up the pace, they sent me home to which I replied "Are you sending me home because I just suck" as it wouldn't make sense to send somebody home, slow or not, if you're understaffed. To which he responded that he called in more people and they're on their way and they've got more seniority than me. Which is understandable, but if it wasn't because I suck- then why not at least wait until they arrive? It's very confusing and there seems to be a lot of politics with the job and I'm just trying to go with it and do as best as I can. But like I said, it's hard when they're not giving me the opportunit(ies) to improve. So how can I work on my loading speed and maintain quality? The training was piss poor and I was immediately just thrown into the job and kind of had to figure it out as I went.
