Tasked with turning around a struggling Internet company, Yahoo CEO Marissa Mayer ordered an about-face on the company's telework policy, instructing all employees that they must now come to the office for work. The policy is meant to encourage face-to-face collaboration and innovation. While the policy shift has sparked a backlash of criticism, particularly among women, some observers say that if it's creativity Mayer is looking for, she may be on the right track. "If you want innovation, then you need interaction. If you want productivity, then you want people working from home," said management expert John Sullivan.
