Carol Frederick spent her life working for women's equality. She was very active in the fight for passage of the Equal Rights Amendment (ERA) in 1972 while she was an intern with the Illinois Education Association. This was the first year that ERA was debated in the Illinois legislature, but it failed to pass. She then served as the Coordinator of Legislative Affairs for the National Business and Professional Women's Clubs, working as a lobbyist. In 1977 she was appointed by Governor Jim Thompson as the Chairperson of the Illinois Fair Employment Practices Commission, later renamed the Illinois Human Rights Commission. From 1980-1982 she served as the Director of Illinois Planned Parenthood Council, and from 1982-2010 she owned her own business.
