Workplace dynamics have been transformed by the effects of COVID-19 and heightened employees’ caregiving roles across different industries. Increasingly, as individuals try to provide care for children, elderly parents and provide health services to family members, how responsive Human Resource Management (HRM) systems are to employees is one of the key factors influencing employee wellbeing and organisational stability. While there has been increased awareness regarding work-life integration, the research investigating the role of organisational support systems and employee retention due to caregiving in the workforce remains limited. This research utilizes a quantitative method, which includes the study of other sources of information for gathering data about organizations and the reporting of their environmental, social and governance (ESG) data to create a global workforce database. This research is concerned with how the extent to which human resource management (HRM) is flexible and responsive to employee needs during the COVID-19 pandemic, as indicated through flexible working arrangements, caregiving leave and employee assistance programs, impact retention in post-COVID workplaces by comparing selected organizations. In general, firms that are highly responsive to the needs of their caregiving employees have significantly lower levels of attrition compared to other organizations and have much higher levels of employee engagement and commitment. The study emphasizes that the issue of caregiver assistance has changed; it is now no longer seen as an auxiliary concern in human resources, but rather recognized as critical to talent retention and, thereby, the long-term viability of an organisation. Finally, the review contributes to advancing the discourse on building people-centred workplaces by providing empirical support and establishing a requirement for the inclusion of caregiving issues within Human Resource Policies and Environmental Social Governance (ESG) frameworks. These findings are of significance to organizations that seek to build a sustainable, inclusive company in the world of work that is quickly changing.
