A local employer confides to you that she secretly does Internet searches of applicants before she calls them in for interviews. She tells you that she has a very established clientele and needs to make sure her new employees "fit in". She's particularly concerned about people with visible tattoos and piercings, but explains that she's also on the lookout for bad grammar, handicaps, and people with gray hair. She explains "my customers expect a fresh, 'All-American' look here. My employees look like the boy or girl next door".
Is she breaking any laws?
If so, which ones and how?
Can she legally avoid hiring people with any of these characteristics?
