"Horrible and unsightly to some and beautiful works of art to others.
My daughter can choose to add whatever adornments she wishes to her own body."
Of course she can, daffy. But she must not be surprised if some people consider them horrible and unsightly. So much so that it may jeopardise her chances of employment (the original theme of this question). To return to some civility (I don't think it was helpful to link tattoos with prostitution) whilst many people are indifferent or find tattoos perfectly acceptable, a large number of people find them unsightly or even repulsive. This is particularly so when they adorn the face, scalp or head. Employers have to consider the impact their staff will have upon their customers and indeed other members of staff. If they believe their customers or staff will be put off when dealing with staff members with tattoos they must take this into account when recruiting.
Tattoos are not everybody's cup of tea and those with them, or thinking of getting them, need to take into account the impact their appearance may have on others. If they do not it is unreasonable to expect their appearance (over which they have control as far as this issue goes) to be ignored. It's no use them saying "It's my body - get over it". Because they will not.
