This study explores the relationship between HRM activities (training, performance appraisal, job enlargement, employee involvement, and work enrichment,) and employees' adaptive performance using the resource-based view (RBV) theory. It was also looked into the role of transactional leadership in regulating these correlations to draw the polices for the post pandemic. Quantitative nature study is conducted and questionnaire was distributed randomly among the Ministry of Health of the Sultanate of Oman and 233 people has participated in the questionnaire survey. PLS-SEM was utilized to analyse the data. In this study, performance appraisal, job enlargement training, and work enrichment all have a considerable influence on employees' adaptive performance. Furthermore, transactional leadership moderates the linkage between job enrichment and employee adaptive performance. As a result, the higher the organization's attention on certain HR policies, the better their adaptive performance. Energy efficient employees improve the performance in the organization and HR practices are important predictors of adaptive performance; thus, managers and practitioners should take into account workers' adaptability to encourage more adaptive behaviour in the workplace. This paper further discusses the study's weaknesses as well as future research directives on HRM practices and adaptive performance.
