Abstract: This study intends to bridge the unattended research gap and add to the knowledge base of ‘human resource management’ regarding the relationships between abusive supervision, and individual organizational citizenship behaviour (OCBI), through the mediation of ‘employee wellbeing’. For the given purpose, a sample of 250 cases was selected to collect data from non-managerial hotel employees from the metropolitan cities of Pakistan. Given responses were analysed in Smart PLS 3.0. Structural equation modelling (PLS-SEM) was used to conduct the necessary tests regarding measurement model and structural model assessment. The study found statistical support for three of the four hypotheses, confirming the deleterious role of abusive supervision in general and the intervening role of employee well-being. The findings have concluded that abusive supervision is harmful for workplaces, particularly when it comes to employees’ citizenship behaviours. Finally, the predictive relevance and r-squared values for the underlying model were also confirmed.
