This document discusses human resource development and training in Nigeria. It defines key terms like employee, training, and development. It outlines the objectives, types (like on-the-job and off-the-job), and components of training programs for Nigerian workers. It examines how training benefits both individuals and organizations by improving performance, reducing costs, and increasing job satisfaction and prospects. While training can positively impact results, more research is needed to understand how to best transfer training benefits across different levels of an organization.
