Based on the Socially Embedded Model of Thriving (SEMT), this research primarily aims to elucidate the underlying mechanisms through which sustainable human resource practices promote employee voice behaviour (VB) – an area that has received limited attention in the sustainable HRM literature. Specifically, it examines the indirect relationship between sustainable HR practices and VB via employee thriving (ET). It also investigates the moderating role of sustainable leadership (SL) in strengthening this indirect effect by providing a supportive contextual stimulus.
Primary data were collected from a sample of 284 healthcare sector employees in India. Data analysis was carried out using CFA and an SPSS macro named PROCESS.
Results reveal that sustainable HR practices have a significant positive effect on employee VB. Meanwhile, the relationship between sustainable HR practices and ET is found to be moderated by SL. ET meditates the positive relationship between sustainable HR practices and employee VB. The study unveils moderated mediation pathway, showcasing the significant and indirect effect of sustainable HR practices on voice behaviours through ET and SL.
This work is carried out in the Indian healthcare sector and may not be generalizable to other cultural settings.
This study offers practical guidance for healthcare organizations to leverage sustainability-oriented HR policies that foster ET, which functions as a key psychological mechanism through which employees can translate their enthusiasm into constructive suggestions.
This study is among the first to link sustainable HR practices to employee voice in Indian healthcare, by exploring ET as the underlying mechanism and SL as a critical boundary condition. This study offers a novel sustainability-driven account of VB.
