The Idea in Brief

• People in professional services believe a 24/7 work ethic is essential for getting ahead, and so they work 60-plus hours a week and are slaves to their BlackBerrys.

• The authors’ research in several offices of the Boston Consulting Group, however, suggests that consultants and other professionals can meet the highest standards of service and still have planned, uninterrupted time off—whether in good economic times or bad.

• Here’s how: Impose a strict mechanism for taking time off, encourage lots of talk about what’s working and what isn’t, promote experimentation with different ways of working, and ensure top-level support.

People in professional services (consultants, investment bankers, accountants, lawyers, IT, and the like) simply expect to make work their top priority. They believe an “always on” ethic is essential if they and their firms are to succeed in the global marketplace. Just look at the numbers: According to a survey we conducted last year, 94% of 1,000 such professionals said they put in 50 or more hours a week, with nearly half that group turning in more than 65 hours a week. That doesn’t include the 20 to 25 hours a week most of them spend monitoring their BlackBerrys while outside the office. These individuals further say they almost always respond within an hour of receiving a message from a colleague or a client.
