I can echo what @WBoTwQ3-quk posted. The times I worked from home, it was for conf calls at 6AM since I'm on the West coast and no one in Rochester/Webster seems to think there's any other time zone than Eastern. :)
When I'm in the office I try and get out for lunch, but when working from home I always just work through it. And then another hour or so after the kids are in bed. And I can't tell you how many meetings I've participated in and work I've done while out on vacation.
The main problem Xerox has had wasn't it's employees. It was senior management.
