A groundbreaking four-year study, set for publication in the October 2009 issue of Harvard Business Review, seems to confirm that getting away from work can yield unexpected on-the-job benefits.
When members of 12 consulting teams at Boston Consulting Group were each required to take a block of "predictable time off" during every work week, "we had to practically force some professionals" to get away, says Leslie Perlow, the Harvard Business School leadership professor who headed the study.
Requiring hard-driving consultants to take time off was "nerve-racking" and awkward at first, says Debbie Lovich, a Boston Consulting executive who headed one of the teams. Some fought the idea, claiming they would have to work more on weekends or draw poor performance ratings.
Ms. Lovich adds: "We wanted to teach people that you can tune out completely" for a while and still turn out good work. The work itself became the focus, "because if you know a night of is coming up, you're not going to let things spike out of control," she says.
