Robert Hohman, the co-founder and CEO of company-reviewing site Glassdoor, talks about how the company has evolved since its early days, when Hohman wanted to merge employer transparency with the gaming sensibilities of World of Warcraft. He explains why letting employees and ex-employees rate a company's CEO was so successful, and why Glassdoor nixed a planned feature to let them rate their direct managers. Hohman also talks about the rules the company put in place to moderate publicly-shared reviews, including what happens when an employee alleges that a manager has sexually harassed them. Plus: Why there's a strong correlation between employees who have a bad work/life balance and CEOs with high approval ratings.
