Strong HRM processes and line managers' effective HRM implementation: a balanced view

Exploring a unitarist and pluralist Human Resource Management (HRM) perspective, we propose a more nuanced view on Bowen and Ostroff's (2004) concept of strong HRM processes. More specifically, we investigate whether strong HRM processes contribute positively or negatively to line managers' effective HRM implementation. The results of a multi‐level model with data from 125 line managers and 899 employees of five organisations show a complex picture. In line with unitarist thinking, we find a positive indirect effect of strong HRM processes on HRM implementation effectiveness via line managers' ability. In accordance with pluralist thinking, we find a negative direct relationship between strong HRM processes and HRM implementation effectiveness. We discuss the tensions in HRM that might explain these ambiguous findings.
