High-performance work system and knowledge hoarding: the mediating role of competitive climate and the moderating role of high-performance work system psychological contract breach

Abstract

PurposeHigh-performance work system (HPWS) has been verified as a promoter of both organizational and individual outcomes. However, this research takes the conflicting view of HPWS to examine the impact of HPWS perception on knowledge hoarding. In addition, competitive climate is proposed to mediate the relationship while HPWS psychological contract breach is hypothesized to moderate the HPWS-knowledge hoarding linkage.Design/methodology/approachA quantitative research design is adopted with data collected from 367 MBA and PhD students in Vietnam. Partial least square structural equation modeling is used to test the hypotheses.FindingsThe perception of HPWS increase knowledge hoarding with competitive climate acting as a partial mediator. HPWS psychological contract breach intensifies the relationship.Research limitations/implicationsThe research provides additional evidences to support the dark-side view of HPWS on employees' outcomes. The adoption and implementation of HPWS should be clearly announced to reduce perceptions of mismatch between expectation and reality.Originality/valueThis study is among the first to investigate the association between HPWS and knowledge hoarding. In addition, the mediating role of competitive climate represents a novelty in HPWS research. Finally, the concept of HPWS psychological contract breach has been introduced to the literature.
