I'll share one ridiculous union story.
When I was a 24 year old engineer I was working at a small company that had a union for the shop workers. Anyway, I had recently completed my MBA and because I didn't go to commencement, I had the physical diploma mailed to me.
However, because I lived in an apartment, I didn't want it left outside. So I had it sent to my work address.
So I get a call from the recieving department on the day it showed up that I had a package. Great. I walked down to get it and carried it back to my cubicle.
A few days later my manager stops by with some questions. Apparently the people in the shop saw me carrying a package (my diploma) and filed a grievance.
Newbie that I was, I just started laughing at the ridiculousness of the whole thing. I explained to my manager what it was and he said, no problem and understood.
The idea that somebody filed a grievance against me for carrying my Masters diploma from Recieving to my cubicle, to me, pretty much said it all. Yes, I know they didn't know what it was, but...yeah.
