Based on ability-motivation-opportunity, social exchange, and job demands-resources theories, this research aims to investigate how high-performance work systems (HPWS) are linked to voice behavior through sequential mediating effects of psychological meaningfulness and work engagement in a Middle Eastern context.

Structural equation modeling was employed to analyze data obtained from a sample of 538 nurses working in various hospitals located in Palestine.

The findings show a positive association between HPWS and voice behavior. In addition, the study findings support the sequential mediation of psychological meaningfulness and work engagement on the association between HPWS and voice behavior.

This study is one of the few examining the effect of HPWS on individual-level outcomes in the context of the Middle East. More specifically, our study is the first to test the association between HPWS and voice behavior, especially in this under-researched context. It is also the first to explore the influence of HPWS on voice behavior through sequential mediating pathways of psychological meaningfulness and work engagement.

Data in this study was collected from 545 nurses working in Palestinian hospitals. Structural equation modeling was used to analyze the data.

The results show positive effect of ethical leadership on organizational attractiveness and diversity-valuing behavior. The findings likewise support the mediating role of psychological meaningfulness on the focal relationships.

This study follows a more comprehensive and a multitheoretical approach and it uses a novel model in an underexamined setting, which is the nursing sector.
