I don't tend to, but my work is reasonably flexible on where I work. Most of the people in my office work from home on Fridays, so I'm usually one of the few people in. I don't tend to take work home with me, but I did yesterday. I was on a site visit for most (but not all) of the day and it was reasonably close to home, so I did an hour or so further at home afterwards. I try not to take my work home though.
