Sydney Finkelstein, a professor of management at the Tuck School of Business at Dartmouth College, encourages leaders to approach their direct reports like teachers. As Finkelstein explains, being a teacher-leader means continually meeting face to face with employees to communicate lessons about professionalism, points of craft, and life. He says it’s easy to try and that teaching is one of the best ways to motivate people and improve their performance. Finkelstein is the author of “The Best Leaders Are Great Teachers” in the January–February 2018 issue of Harvard Business Review.
