HRM involves a range of activities related to the acquisition, development, motivation, and retention of employees, as well as ensuring compliance with labor laws and regulations. This research paper aims to provide a comprehensive review of the impact of social media on human resource management (HRM). The widespread adoption of social media platforms has revolutionized communication and interaction patterns, and this transformation has extended to the field of HRM. The paper explores the multifaceted influence of social media on various HRM functions, including recruitment and selection, employee engagement, employer branding, training and development, and employee relations. By examining existing literature and empirical studies, this paper presents an overview of the advantages, challenges, and best practices associated with leveraging social media for effective HRM. The findings suggest that while social media offers numerous benefits, organizations need to carefully manage its use to mitigate potential risks and ensure positive outcomes for both employees and employers.
