Warning all UPS customers UPS does not care about serving your packages. I'm a part-time UPS employee.
UPS part timers get paid over time after 5 hours.
I work in a large sorting hub, if it's getting close to the 5 hour mark my supervisor will not allow me to get "hot" package's to the correct trailer to make service to avoid paying me and other employees over-time. They would rather have your package become a "service failure." This is from a company that has made 2.2 billion dollars in net profits last year.
