Would it be okay to tell my employee to cover her tattoo?
Why do you want your employee to cover her tattoo?
It's her fault that I lost my job. If she had not shown up with that tattoo on the wedding day, I wouldn't get fired.
I'm sorry that it happened to you. You should not try to control other people's appearance. She can't get rid of the tattoo, but you could ask her to cover it up.
I don't care.
It's fine to have a little bit of petty feelings about people with tattoos after what happened to you, but you shouldn't try controlling people's appearance. How would you feel if people tried to control what you do?
