Between dog walking, grocery store trips, attending to children, most people are working <= 30 hours from home as it is

(If you're in office, replace that with walks around the building, coffee/smoke breaks, long lunches, hanging out in your co-workers cube talking about whatever...)

For people who can do those (mostly the ones doing creative activities, such as software, marketing, etc.) the 30 or 40-hour week doesn’t matter anyway. This is more important for service jobs or physically intensive jobs, where the hours spent on the job may correlate pretty heavily with the total work done by the worker.

Who said you're not working when walking your dog? I certainly think better when I walk than sitting at my desk.
