Working from home has actually increased productivity for the two teams I manage. Far less waisted time with "drive by" coworkers. We're also more flexible with time off when needed.

Add to that my ability to help around the house. Before I was basically absent from the house for 9-10 hours a day M-F. Now I can make my kids lunch, go on a walk with them, or sign off a little early and go to a park.
