That whole Teamster concept really steamed me . . . those guys made more money, didn't have to dryclean or starch their shirts, didn't have to wear a tie, could call-off when they were hungover (if they had the "points" to burn), and worked fewer hours than I.
That, and if they didn't like you (not in my case) they'd throw nuts and bolts at you when you weren't looking . . . and don't get me started on my asshat boss who wanted me to cross their picket line when they went on strike.
When I was a kid (10-15) I had paper routes and all of the drivers were Teamsters. It didn't take me long to catch on that "fairness" wasn't exactly a priority. I'm not saying the shenanigans were egregious, but I made sure to pay the bill early every week and never let a complaint rise above the driver to anyone at the newsplant. Oh yeah, and scoping out choice garbage pickings didn't hurt either. Once, my mom told me to have the driver help me with a dog problem...sheesh Mom don't do me any favors...lol.
These experiences helped me out later in life at a quaint little spot called McCormick Place.
