My secretary has just got a tattoo on her arm. It is of a flower, but it is completely visible. Should I fire her?

It is against company policy, and looks tacky. She said she got it because all of her girl friends got one, and it holds special meaning for her.

But she knows that we have a strict dress code that includes hairstyle, piercings and tattoos. By all rights, I am within my power to let her go. But, I think that is really harsh. I just think that she fell under a spell of peer pressure and forgot that she has an image to maintain at work. Afterall, that is part of the reason why she was hired.

I am toying around with the idea of changing her job position to something not so visible. That way I can still keep her, and she can still earn money, and keep her tattoo. However, she will not like the options. The only positions that I have that allows an employee not to follow the dress code is the Cleaning Lady, and the dock-workers. I don't think that she'll make a good "loading girl", so housekeeper it is.

How can I address this issue in a positive light to her, or should I just go by the book and fire her?
