I work completely out of my home.
I log into work via a VPN and never go into the office (well, I won't say NEVER, just hardly ever.) I do talk on the phone to the office several times a day.
I manage online search engine bidding, marketing, oversee online orders, all responsibilities accomplished just as easily from my home office and probably more efficiently because no one is here to interrupt.
Plus it's more than a 9-5 job, it's a check on it, off and on throughout the entire day type of job, so I have freedom to come and go from home, because much of my work is accomplished early AM and late PM.
I think working from home makes more sense and some jobs are handled much more efficiently from home.
My info would be counted through the jobs data because I am not a "contract employee", but a regular employee.
The best part for me is being home with my 15 year old son during the summer, and being home every day after school. Going to the stores, bank, etc. during the middle of the day is much less busy than evenings, and weekends also.
