The United States’ manufacturing sector has lost a substantial number of jobs since 2000 due to competitive challenges presented by the global market (National Association of Manufacturers, 2007a). This quantitative, descriptive correlational study examined the relationship between employee self-efficacy, perceived supervisor leadership style and employee engagement for a blue-collar work population. Analysis of the data indicated a moderate positive relationship between perceived transformational supervisor leadership style and employee engagement, and a moderate negative relationship between perceived laissez-faire supervisor leadership and employee engagement. The results of the study support the conclusion that through improved selection and training of factory-floor supervisors, manufacturing leadership can enhance blue-collar employee engagement to organizational strategy in support of business performance and U.S. manufacturing ability to compete in the global marketplace.
