Description: This article is a review of Peter F. Drucker’s 1980 book ‘Managing in Turbulent Times.’ The reviewer notes that this is a troubling book ‘to anyone familiar with the unsettled outlook for our economic, political, and social environment,’ because of Mr. Drucker’s credibility as a management analyst, and because ‘the turbulent times that he identifies call for changes in management attitudes and practices that are difficult to make.’
