Like many of you, I was surprised to see Yahoo’s recent announcement that employees will no longer be allowed to work from home. The responses in the media have been predictably varied and, at times, harsh. Yahoo’s rationale, at least the explanation I have seen, is that collaboration and innovation work better when people are physically together. Fair enough, although one could make the argument that everyone doesn’t need to be together all of the time. That, however, is another discussion entirely.
