CASE STUDY: Kyle works at a major aerospace company as an engineer. He has the chance to change his work hours to start an 8 hour shift (plus 30 minutes for lunch) as early as 6am. He knows that there is a shift of thousands of factory workers starting work at 7am and leaving at 3:30pm. Kyle sets his work hours for 6:30am to 3:00pm. He avoids the big commuter rush in the morning and afternoon. He gets off work in time to get to his bank, do errands, and have some daylight left for recreation. He does have to awake at 5am. But the alternative--arriving at 8:30am--would cost him more in terms of commuting time and the aggravation of never being able to enter banks, many businesses, museums, and many cultural events.
