The first ever pregnant CEO of a Fortune 500 tech companyMayer soon after being appointed as the new CEO of Yahoo, announced that she was pregnant and she expected her first child in October 2012. She gave the news exclusively to Fortune, but the word starting spreading like wildfire seconds after it went public. She set a precedent as the first woman to ever take the top position while pregnant. And, in late September, when she had her first child, she only took a couple weeks off for maternity leave. Yahoo! announced that Mayer is working from home this week but she may reappear in the office in person after only a week of maternity leave. The self-described geek prompted much debate about how pregnancies affect women in the workplace. However, in a striking announcement, Mayer demanded that all remote employees report to office facilities by June 1. Her decision elicited a flood of opinion from both sides—those who agree with CEO Marissa Mayer and Yahoo's HR chief that “communication and collaboration” are required for innovation to flourish and others who say Yahoo's ban on working from home is a throwback to the stone age.
