International human resource management (IHRM) deals with managing human resources on a global scale. While HRM and IHRM share similar basic functions, IHRM is more complex due to factors like operating across different cultures and countries with varying laws and standards. Globalization and increased foreign investment drove the need for IHRM to help multinational corporations manage employees internationally and gain a competitive advantage. IHRM aims to balance local responsiveness with global integration through flexible policies and helping transfer knowledge across borders.
