Pull into work like it was just another day, to find 7 UPS trailers in the back row. This seems a bit odd to me, seeing as we have a huge yard for them to park in, just behind the fence. (near the back of the building). I asked my preload manager about this, and he said I was on a need to know basis, and didn't need to know. Just wondering why they would block 50 parking spots to put them in? You should have seen the utter mess, when the drivers came in to park. 60% of people were located in the RED zone.
