International Human Resource Management (IHRM) focuses on the HR challenges faced by multinational companies in managing their workforce across different countries. Key differentiators between domestic and international HRM include complexities from diverse cultures, legal frameworks, and the necessity for tailored policies regarding recruitment, compensation, and expatriate management. Major challenges in IHRM involve expatriate failures, cultural integration, and the orchestration of human capital in a global context while ensuring compliance with varying labor laws and practices.
