There is an invisible army of people deep inside the world´s biggest and best-known companies, pushing for safer and more responsible practices. They are trying to prevent the next Rana Plaza factory collapse, the next Deepwater Horizon explosion, the next Foxconn labor abuses. Obviously, they don´t always succeed. Christine Bader is one of those people. She worked for and loved BP and then-CEO John Browne´s lofty rhetoric on climate change and human rights--until a string of fatal BP accidents, Browne´s abrupt resignation under a cloud of scandal, and the start of Tony Hayward´s tenure as chief executive, which would end with the Deepwater Horizon disaster. Bader´s story of working deep inside the belly of the beast is unique in its details, but not in its themes: of feeling like an outsider both inside the company (accused of being a closet activist) and out (assumed to be a corporate shill); of getting mixed messages from senior management; of being frustrated with corporate life but committed to pushing for change from within. The Evolution of a Corporate Idealist: When Girl Meets Oil is based on Bader´s experience with BP and then with a United Nations effort to prevent and address human rights abuses linked to business. Using her story as its skeleton, Bader weaves in the stories of other "Corporate Idealists" working inside some of the world´s biggest and best-known companies.
