This has been a really interesting thread. I've had tattoos since I was in my 20's - I was careful to get them in places they generally didn't show or wouldn't if I didn't want them to. When I was 30 I pierced my eyebrow - wore a ring for a long time although I've since gone to a barbell. Recently I got chest tattoos and, although they are still in places I can cover them if needed, I wear a decent number of shirts that show peaks of them although I don't when I don't know my audience.
I am currently a Director in IT at a telecommunications company. One of the other Directors is working on a full sleeve but generally goes for the "long sleeve button down man's corporate uniform" look. Our boss - SVP - isn't into tattoos, something I found out after my co-worker gleefully pointed mine out to him (they go way back, so he knows it's a safe button to push).
My coworkers viewpoint is that for people like Bossman knowing people like me and coworker are good for them and that someday people will look for not only employees but leaders who are tattooed as it shows a certain sort of creativity and personal expression that you don't find in other places. His thought is that tattoos are on a path to be an asset vs a possible detriment.
I know that I personally have made the choice to put my tattoos where I can hide them if I need to. Luckily, I work in an industry (IT) that accepts some more personal freedoms than some others might allow. Still, I recognize that the world doesn't conform to me and I made my choices based on that. I applaud those of you who fight a different fight than I have chosen and thank you for it!
