The document summarizes two influential leadership studies from Ohio State University and the University of Michigan. The Ohio State studies identified two critical leadership dimensions - initiating structure, which is task-oriented, and consideration, which is people-oriented. The Michigan studies similarly found two styles - production-centered/task-oriented leadership and employee-centered/relation-oriented leadership. Both studies found that while production-oriented styles increased productivity slightly more, employee-oriented styles led to greater employee satisfaction and less absenteeism.
