Yes, I used to work at UPS.
Here is the basic job day.
Every morning, you would get up at around 4 am to head into work. When you got there, you got into what they call the "banana room". This is a bright yellow room where you can get breakfast (bananas) and the color is supposed to wake you up and motivate you.
You then get with your co-worker group (or friend-circle as they called it). You all stand in a circle and say the UPS slogan and the "team" leader says some motivating words. Everyone hugs those around them and then get to work.
Then, it takes a bad turn.
The "Box Man" or the guy in charge instructs everyone of what to do from a podium with a megaphone. This is really annoying at 5am. If you look small they will have you pick up the biggest boxes because it makes them laugh. You will probably have a hernia by the 2nd week. Some of these boxes weight 250+lbs. Also, if you ask someone for help moving a box, you will have to sacrifice that days pay to them. It is a stupid system.
You do that all day with four 10-minute breaks and then you go into the "Blue and white" room, which is BW, for better worker. Here, if you didn't meet your days goals, you had to do push ups and stuff to get stronger. Oh, and I am just kidding about all of this. Boredom > Me.
