New York (CNN) -- When a Goldman Sachs employee unexpectedly wrote a scathing op-ed in the New York Times in March 2012 about why he was leaving the investment bank, he painted a picture of a "toxic" workplace that embraced morally corrupt practices at the expense of their clients. Edith Cooper's reaction wasn't rooted in damage control. Instead, as the firm's global head of human capital management -- overseeing more than 30,000 employees -- she wanted to know why. "It was to figure out why it was that there was an individual who worked at Goldman Sachs who felt that the only way they could voice their experience was to write an op-ed in the New York Times," she recalls to CNN's Poppy Harlow.
