Ferguson began his radio career in Chicago as an intern at
WYTZ-FM in Chicago and later was a producer for Chicago on-air personality
John Records Landecker. He then was a producer for the "
Morning Zoo" on WYTZ-FM. He later began hosting a morning show on WMMZ-FM in Gainesville/Ocala, Florida. Ferguson also hosted an evening shift at WHXT in Allentown, Pennsylvania and morning shows on WPXR in
Rock Island, Illinois and WZOK in Rockford, Illinois. Ferguson later worked at KWMX-FM in Denver. Ferguson and Kathy Hart, who he had never met before were paired up as cohosts of the morning show at WTMX in Chicago in 1996, and were named to the position. The duo, known as "The Eric & Kathy Show," went on to tremendous ratings success, and appeared in a successful, multiyear ad campaign that placed their faces on billboards around the Chicago area. In 2001, Ferguson signed a five-year, $5 million contract renewal at WTMX. In 2016, Ferguson and Hart (whose birth name is Kathy Achenbach) were inducted into the
Radio Hall of Fame as "The Eric & Kathy Show". On September 27, 2021, the Chicago Tribune broke the news that Ferguson had been sued in May 2021 in Cook County Circuit Court by a former producer on his show, Cynthia DeNicolo, who alleged that Ferguson had abused his power to coerce sexual favors early in her career, and then blocked promotions as punishment after she refused to resume an unwanted sexual relationship. Ferguson was taken off the air soon after, and formally left the radio show in late October. According to the lawsuit, Ferguson is accused of coercing DeNicolo, who then was known as Cynthia Skolak, into performing oral sex about twice a month from January 2004 until August 2004. Former co-host and long-time radio station employee Melissa McGurren joined the suit against Ferguson, alleging workplace sexual abuse and misconduct. The
Equal Employment Opportunity Commission is also investigating. On June 27, 2023, the Chicago Tribune reported that the woman who accused former WTMX-FM morning host Eric Ferguson of coercing her to perform sexual acts, then retaliating against her at work when she stopped complying, has dropped her explosive lawsuit against the sidelined radio personality. The lawsuit by former assistant producer Cynthia DeNicolo, filed in May 2021, sparked a tumultuous two years of public battles for Ferguson and Hubbard Radio Chicago, the company that owns the adult contemporary station at 101.9. Lawyers were due in court for a case management conference in preparation for a tentative Jan. 21 trial date. But court records show that DeNicolo requested to dismiss the litigation. ==Personal life==
