Scumbag UPS driver

Yes doing there job while running on a specific schedule makes them scumbags

Well, I don't know on what basis does UPS work, but isn't there somewhere your chance to say when (I mean in what o'clock) you prefer to have your delivery delivered?

I work for UPS. I'm in the process of trying to get a full time driving position. I've driven seasonally. The driver doesn't have a schedule per say. You are given a list of your stops and you have deliver them as efficiently as possible. Management is incredibly strict. They track your deliveries down to the second. When you are out there you are more interested in just getting stops off as fast as possible. They don't allot you any time to deliver to anyone at specific time. If you aren't there at time of delivery you can always sign your delivery notification (so long as you don't live in a high risk area/apartment/ or are receiving a high value pkg) and they will driver release it to you. Or you can always just call up your local center and retrieve the pkg there at your earliest conveince. Honestly drivers get caught in the middle of giant shit storm between customers and management. It's no surprise to me when drivers snap like what happened in Birmingham last year.

The UPS guy always leaves whatever I ordered even if no one is home

What do you mean no one is home? UPS doesn't care, they will drop off your package whether anyone is there or not. to schedule a delivery where you need someone present to sign costs extra shipping for you and it's not easy to do. It's hassle just trying to get a delivery the way you want.
