I would recommend this book both to those who work in an office and those who work from home.
I bought the book at the recommendation of the author, after meeting her at Witchfest International 2004 in London. Once you read past the slightly American terminology (it was written for the American market, I think), this book has a lot of useful information. I find it useful particularly for those moments when I have been asked to explain why I work in a certain way, because that way appears to generate the right sort of results. There is a good level of humour involved, so that the subject matter does not come across as too heavy, or, for that matter, too weird. The suggested exercises are not too complex, which meant that I was more likely to give them a go. Those chapters which referred to topics with which I was unfamiliar have provided a decent grounding, which I can take further if I so wish. The appendices are fairly comprehensive for the subject matter covered in the book.
All in all, a very interesting twist to the usual 'improve your work life' type of book.
