It’s totally not worth it anymore. Package is the only job where management is looking for any reason to bang you up with write ups,suspensions and or walked out. Every other job at UPS is don’t steal and you won’t get fired.
This is widely overblown, places were that takes place is usually just because the people in charge are just dicks. People that feel that way usually are trying to game the system and get on the radar of management. I've been doing it for 11 years so far and never once saw it on a large scale.
The drivers that do get in trouble a lot are because they do try to purposely work slow, late all the time, complain that they cant finish their routes all the time or other things. If you just show up and give a fair days work for a fair days pay, you can just punch in and punch out with no one batting an eye on you.
