Pros
UPS has some great people as part of the team that you interact with on a daily basis. The learning curve is huge, so you are always challenged to succeed in a mostly positive way. There is room for advancing your career and you can move into different departments and you have some input in career reviews. The benefit package is very competetive. The day absolutely flies by because you are so busy so it seems like you get to see your family soon after you wake up.
Kontras
The stress level is very high, and the monetary compensation could be higher for the level of responsibility that you have. I believe that most people feel overloaded withing their respective jobs. The training is poor. The praise and positivity is low when you do a good job so its hard to know how well you are doing with very little feedback unless you make a mistake.
