Marissa Mayer, the new CEO of Yahoo!, recently created a fuss by issuing an edict that forbids anyone at the company to work from home. Mayer’s demarche received a lot of press coverage, probably more than it deserved. That may not be so surprising: she is a woman, and she allegedly has a nursery for her baby next door to her office. Above all, people seemed to react to the categorical nature of her decision (why everyone?) and to the irony that Yahoo! is a tech company (don’t they know about Skype?).
