Hunter was hired as a research bench chemist for Polaroid Corporation in Cambridge, Massachusetts in 1968
In 1970, upon the discovery of her employer’s involvement in the South African apartheid system as the producer of the passbook photos, she and her future husband, co-worker Ken Williams, formed the Polaroid Revolutionary Workers Movement (PRWM)
Hunter and Williams became the first American activists to challenge their employers’ South African investments. They led a seven-year boycott against Polaroid that included testifying before the United Nations and Congress about American corporations profiting from assisting the South African government.
In 1971, Polaroid fired both Hunter and Williams, but the PRWM prevailed and by 1977 Polaroid completely pulled out of South Africa. After her involvement in the PRWM, Hunter went on to work as an educator. Hunter received the 2012 Rosa Parks Memorial Award by the National Education Association for leading the effort that led to sanctions against apartheid in South Africa.
The South African Partners presented the Amandla Award to Hunter in 2012Hunter has continued her activism including being involved with Massachusetts Against Hewlett Packard. Massachusetts Against Hewlett Packard has participated in what has become an international movement calling for a boycott of the technology company Hewlett-Packard, which has provided technology such as servers and computers to the Israeli government and military, which has used it to create a population registry for the Israeli occupation of Palestinian territories since 2008
