This chapter provides an overview of human resource management (HRM) and why it is important for non-HR managers to understand HRM concepts and practices. HRM encompasses all decisions related to managing employees, such as hiring, performance reviews, compensation, and promotions. While HR departments handle strategic HRM issues, front-line managers are increasingly responsible for day-to-day HRM activities. The chapter argues that HRM involves more than just common sense and that managers benefit from training in HRM practices in order to effectively manage employees.
