I’ve been working one day a week from home for a little over a year now. There are many reasons I’d recommend it to anyone who is even marginally a self-directed individual. It does, however, feature two distinct problems that I’ve found so far.
The first is that in those rare moments when you actually need to talk to someone immediately you’re limited to phone, email, or text. If you happened to be sitting in a cube farm in those moments you could at least add “wander over to wherever that person is supposed to be” to the list of ways to get in touch with them. Needing someone right-the-hell-now, though, is such a rare occurrence in my experience that the issue is hardly worth considering.
The second, and more problematic issue, is that doing the work from the comfort of your own home establishes in clear terms just how utterly unnecessary sitting in one specified desk in one specified room of one specified building really is in the course of day to day activities. It makes then going to sit at that desk, in that room, in that building on the four other days of the work week even more difficult than it would be otherwise. Sure, I suppose there are a handful of good and legitimate reasons for needing to spend time in an actual office, but for all other times I have not one single clue why anyone would want to endure more time in cubicle hell than is absolutely necessary to getting the job done.
