The working world has changed drastically. Gone are the days when corporate employees commute to the office Monday through Friday for a 9-5 job, have weekends off, and take two weeks of vacation every year. Spend any time on the highways of metro Boston and you will see that the morning commute begins before sunrise. There are about two hours between 11am and 1pm when the roads are clear, but by 1pm, the highways begin to jam with commuters on their way home. And the roads stay busy until well after 7pm. The hours of the workweek have changed.
