I think that this study fails to address that they may confuse cause and effect. What is the reason for a telecommuting arrangement? Why doesn't that person just move closer to the job location? The answer is often that he has family ties. I would suspect that telecommuters are significantly more likely to have families, and that may have a pronounced effect on their views of their work life.
I don't know, my reasons for working remotely have never had anything to do with family. Even now that I've got the wife & kid, they're not the reason I'm remote. To put it bluntly, nobody has an office at the beach. Certainly not the beach in the tropics where I want to be. If there was a Google campus on a remote reef pass in the Mentawais, I might consider taking a seat in a cubicle. But there's not. We're living…
Here's what does make me choose to work from home, usually one day a week, in no particular order of importance:
# Avoid driving. Santiago is a jungle on wheels and even one day of not having to deal with it helps immensely.
# Wake up later than usual and/or have a short nap after lunch. It might make me spend less time doing my work, but I'll be a lot more focused on it.
# Listen to the music I want, on my speakers, as loud as I want (within reason, of course). At the office I use headphones, to avoid bothering my co-workers, but it's really not the same thing.
# My coffee might suck compared to Starbucks, but it's a lot cheaper than it. And it's infinitely better than the free coffee at the office.
# My home computer has no annoying web filters. I can hook up my company laptop to its VPN and use my home computer for browsing in those idle moments.
# Hot water! Believe it or not, Chileans don't have a habit of washing hands with hot water. It probably has to do with the fact that they use mainly gas to heat water. Whatever the reason, being able to say "and now I'm going to wash my hands with hot water" is a really pleasant change ;)
In short, it's creature comforts that drive my decision to work from home. Most of that stuff could be improved by living closer to the office or the company providing better "stuff" on their premises, but those solutions seem rather inefficient compared to giving employees freedom to choose to work from home.
