Apparently there was some business at the University of Miami about unionizing recently, and the union won; I wasn't around for the drama but I've heard about it. Knowing the background makes this conversation I overheard just savage technology:
Janitor #1: Hey, you workin' hard?
Janitor #2: Not around here, man (chuckles)
Janitor #1: Yeah, haven't you heard we have a union now? (both chuckle)
Thanks, organized labor!
