I used to work at FedEx, and while most people did try to get all the packages in safely and “this way up,” they just want us to pack so many boxes into each truck that it becomes impossible by the end of the shift no matter how good you are at Tetris, and you end up just having to put things wherever they fit, even if they’re crushing another box. But also, yeah, there was one guy who took great pleasure in punting boxes into his truck, so pack that shit up good.
