Back in 2009 I worked part-time at the early morning shift loading UPS's brown delivery trucks. I made above minimum wage with no option of overtime yielding ~12k/year. They had an education credit of 1.5k/semester provided you were a full-time student (12+ credits/semester). I don't remember about the health insurance because I was under my parents'. At that time there was a 10 year wait queue for full-time employment because it's primarily seniority based. And the Teamsters union initiation dues suck your first month of pay.

Oh, make sure to properly pad your fragile packages because they may or may not be pushed, shoved, flipped, thrown, or dropped depending on how busy it is.
