Until you celebrate with employee buddies one time where they see it. The word will then be out. And what about company parties, swimming, beaches, etc.
Except I do not socialize with my employees - IE hang out.
At a company party where people are partially clothed, all the tatts are exposed by those who have them (not everyone is anti-tatt by the way), besides everyone would be to busy looking at my Italian breasts to notice my tatts.
