Jeanne has to commute to work three days a week, but on the other two days she works from home. She gains nearly three extra hours on the days she doesn't commute and feels more focused on work, rather than stressed by traffic. The flexible work schedule has reduced her stress, given her more time to exercise and even increased her productivity.
The technical work she does requires intense concentration, and her home office gives her the peace and quiet she needs. She saves her most intense thinking and writing for those days, knowing she's more accurate and effective. Plus, she plans ahead with colleagues so that she's accessible when they need her, without constant interruptions.
