Because of the COVID-19 pandemic, the world has experienced major technological and procedural changes that will continue in the post-pandemic age. For this reason, firms are expected to learn from such an unprecedented experience and ensure that the managerial and workforce practices in the post-pandemic period are directed toward rebuilding and reinventing the workplace. Within the scope of the research topic: “Diversity, Innovations, and Entrepreneurship in Post-crisis Periods”, this study accentuates the positive impact of human capital development programs in enhancing employee performance. Moreover, the roles of resilience, empowerment, and mimetic isomorphism are analyzed to better enable firms to learn from their past experience and develop practices that fit the agile environment. A questionnaire was administered targeting 370 employees in 12 SMEs in Lebanon. A conditional analysis was used to test the hypotheses through SPSS, PROCESS. The results of this study showed that the deployment of developmental programs is deemed indispensable for enhancing the performance of SME employees and helping them overcome the challenges posed by the pandemic through empowerment and resilience. This study can be useful for academics who might benefit from its theoretical implications and prospective directions for future analyses. Moreover, its results can also be helpful for practitioners, specifically managers of SMEs who are seeking to reinvent their workplace in a responsive way in the post-pandemic age.
