From my experience, I would say I liked how the job kept you moving. It was constantly stop and go and grab the packages and deliver them then on to the next stop. It made the day go by quickly. I also liked the interactions when delivering packages. People were usually really friendly to you. I also liked that I got to work with different drivers and hear their experience with the company and see different parts of town.
I didn’t like having to work out in the cold, but the driver would give you gloves and hand heat warmers which helped a lot. Not to mention the uniform UPS gives you is extremely insulated.
