Mitsubishi Motors Corp. will hire two female managers and offer one-day sexual harassment prevention training at its manufacturing plant in Normal, IL. That's the gist of a plan crafted by former U.S. Labor Secretary Lynn Martin, Mitsubishi's main spin doctor called in to heal the company's public relations ailments, after 29 female employees last April charged that they were groped, fondled and otherwise harassed at the Illinois assembly plant. But Patricia Benassi, the attorney representing the women, is not ready for compromise: "I don't consider training people about sexual harassment anything that's revolutionary or unusual in corporate America."
