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.
