There was an article in the blog Parent Dish yesterday about a school district requiring teachers with tattoos to keep them covered. Apparently they're a distraction to the kids, or send a message about tattoos being acceptable that somebody doesn't like, or something. Personally, I'd say that if you want to discourage students from getting tattoos, seeing a bunch of teachers sporting them might make them somewhat less of an instrument of rebellion. With "body art" being more and more mainstream these days, I wonder whether future generations will begin to find it terribly uncool?
I've never noticed a tattoo on my kids' school teachers, and I don't know that it would bother me particularly. Not as much, anyway, as the speech therapist at my kids' elementary school whose thong used to show prominently above her pants when she sat on the bleachers at assemblies and leaned forward. Don't know if a tattoo was also visible; I was too embarrassed to look. I'll bet some fifth-grade boys weren't, though.
