"Her voice is totally different than what you hear on TV," Gibson tells WCBS-TV's Deborah Garcia in an exclusive interview. "She's a totally different person."
Gibson, a native of Romania, says she didn't know who Campbell was when she became her housekeeper in November 2005. But she said she soon learned her employer was someone to fear and almost impossible to please.
"Sometimes I was out of my breath. I didn't know what to expect," Gibson said. "If I didn't have to work for money I would have quit that place after a couple of days."
Gibson asked the agency that placed her there to relocate her, but that never happened. So for two and a half months Gibson says she endured constant insults, verbal and, at one point, physical abuse from Campbell.
"I didn't hear her coming from behind and she charged against my back of the head," Gibson said. "I said, 'Wow, what is this for?'
"I said, 'I don't understand. Why you hit me for?' She said, 'To teach you a lesson not to steal no more.' "
Gibson quit immediately, and 10 months later filed a lawsuit against Campbell, asking for punitive damages. But Gibson claims she is not motivated by money.
A New York Supreme Court judge recently ruled that numerous allegations of abuse by Campbell's former employees could be admitted as evidence. The next time both sides will be in court is October.
Attorneys for Campbell have not returned calls for comment.
