Servant Leaders' Use Of High Performance Work Practices And Corporate Social Performance, Michelle Kathleen Fitzgerald Preiksaitis

Walden Dissertations and Doctoral Studies

Business researchers have shown that servant leaders empower, provide long-term vision, and serve their workers and followers better than do nonservant leaders. High performance work practices (HPWPs) and corporate social performance (CSP) can enhance employee and firm productivity. However, when overused or poorly managed, HPWPs and CSP can lead to the business problems of employee disengagement, overload, or anxiety. Scholars noted a gap in human resource management research regarding whether leadership styles affect HPWPs and CSP use. This study examined the relationship between leadership style and the use of HPWPs and CSP, by using a quantitative, nonexperimental design. U.S. business …
