High-performance work systems and job performance in the mining industry: the moderating role of supervisor support and well-being

Abstract

The purpose of this research was to examine HPWS and job performance, the moderating role of supervisor support and well-being among employees in the Ghanaian mining industry. The study was conceptualised on the premise that mining companies in Ghana continue to face challenges with their employees regarding job performance issues, such as utilising poor work methods which yield errors causing injuries, leading to lost time. These ineffective working practices and errors negatively influenced the performance of employees. The study followed the quantitative approach and explanatory research design. It involved a survey of a stratified random sample of 428 employees from three mining companies in Ghana. The data were analysed using partial least square-based structural equation modelling (PLS-SEM). The analysis revealed that HR practices that enhance abilities, motivation, and opportunities boost task and contextual performance. The study demonstrated that supervisor support could provide social support amid the HPWS to act as a buffer and improve contextual performance. Additionally, it was indicated that wellbeing moderated the HPWS and contextual performance. It was recommended that HR professionals ensure that HPWS provide employees with KSA and motivation to complete tasks to eliminate errors. It was also suggested that HR managers implement several initiatives to encourage supervisors' participation in formulating and implementing HR practices. In addition, it is recommended that HR managers ensure that organisations invest significantly in a conducive work environment to improve their employees‘ well-being.
