But visible tattoos aren’t the equivalent of the tie you don’t like. It’s like coming in for a job interview in shorts and a t-shirt. In some cases, nobody will care; in a lot of cases, they will and it shows a bit of a lack of judgement to presume that nobody would care.
Whether or not I personally care about tattoos (I don’t), if I’m making the decision for someone’s job, a tattoo is a negative in many circumstances. I could be worrying that my more conservative superiors will think poorly of my applicant, and by extension me; I could be concerned about contact with clients who weren’t more open-minded. As a hiring manager in my current company? Pah, I could care less. But then again I probably could care less if someone came in wearing a t-shirt either, if I thought they were really skilled and would fit in, because a) we are extremely casual in dress here, b) our culture is pretty eclectic, and c) I work pretty closely with the owner and know for a fact he’s very non-judgemental and rational. It helps I work for a very small company that has virtually no face-to-face client contact. If I was working in an average corporate environment, visible tattoos would be a concern. It’s a conscious decision weighted with more concerns than my own personal aesthetic taste.
