Many of the comments are focused on how workers should be evaluated. The article is discussing how workers are evaluated. In fact, the authors emphasize:

"Managers may not be aware they are making evaluations based on face time."

You can argue that managers should be aware of a bias in this area and strive to minimize its effect. However, workers need to simply be realistic about the effect of working remotely - regardless of whether it seems fair to them. Personally, I prefer to work remotely - but I have always been wary about not spending enough time in the office because of the tendencies described in the article. Physical presence is a powerful thing, and difficult to ignore. Email, IM, Skype, and phone calls are much easier to ignore.
