1. Hours - work from 10 30P - 3 30A or so, no such thing as rush hour traffic getting to/from work at that time. Plus going to WallyWorld after work for groceries at 4-5 AM when no one is there sure beats standing in line behind 50 people in the middle of the day!
2. Paid workout.
3. No need to deal with idiots in the general public (however idiot co-workers/supervisors are another story)
4. The other sorters in my area are for the most part really cool people, and we always end up making jokes about stuff all night with that particularly sardonic brand of humor that comes from working for Brown.
5. Job satisfaction derived from doing a hard job well. Most of our new hires can't hack it after a week or two, sometimes even less. I'm only average height and skinny and it's always fun when I get some newbie unloader who looks like a football player and thinks he is hot stuff and can blow me out, and he's tired by truck #2 because he hasn't learned to pace himself or built up stamina.
6. Double shifting (if/when possible, though not since last peak season) meaning you can get over 8 hours working a "part time" job. Especially when I could go in on twilight and unload package cars or break jams on a PD...Easiest. Money. Ever.
7. I know people who have high-paying jobs for big-name companies who don't have anywhere near as good benefits (especially the free health insurance)
8. The fact that several sups I know have said I should consider turning in my letter - not worth it to me, seems like a dead-end road, but I at least took it as a complement.
9. I remember working in retail I hated my job often because for a long time I sat around bored as hell staring at the clock and wondering how long my day was going to drag on. Not an issue at UPS, the busier I am and the harder I work the faster the time goes by.
10. When you work in the hub no one gives a damn if you wear a 5-year-old T-shirt with holes in it, because it's comfortable in 100-degree heat, or that I have long hair (yeah, got to chop it off when I go drive, but with the $$ increase I will do so with a smile)
I guess that's my top 10??
