Green Human Resource Management (Green HRM) has emerged as a pivotal approach for organizations aiming to align sustainability goals with human resource practices. The COVID-19 pandemic has not only disrupted traditional HR processes but has also underscored the urgency of sustainable development and organizational resilience. This research paper explores the opportunities and threats of Green HRM in the post-pandemic era, emphasizing its role in integrating environmental sustainability into core HR functions such as recruitment, training, performance management, and employee engagement. Key topics include the utilization of technological advancements to streamline green practices, the fostering of an eco-conscious corporate culture, and the development of innovative strategies to engage employees in sustainability initiatives. Furthermore, the paper examines the challenges posed by economic, social, and environmental factors, including resource constraints, resistance to change, and the need for balancing short-term recovery with long-term sustainability objectives. Through an analysis of case studies and best practices, recommendations are offered to enhance the implementation of Green HRM as a strategic imperative for sustainable growth, employee well-being, and organizational success in the post-pandemic recovery landscape.
