Book excerpt: The Encyclopedia of Human Resource Management is an authoritative and comprehensive reference resource with almost 400 entries on core HR areas and key concepts. From age discrimination, to zero hours contracts, each entry reflects the views of an expert and authoritative author. The terms included vary from singular concepts such as performance appraisal and industrial conflict, to organisational behaviour terms including organisational culture and commitment; and broader management terms such a resourcing and management development. Each entry provides a list of references and further reading to enable the reader to gain a deeper awareness and understanding of each topic. This book is an ideal companion to a standard HRM textbook, and both undergraduate and postgraduate students will find it to be of value. It will also be useful for academic researchers, HR practitioners and policy specialists looking for a succinct expert summary of key HR concepts.
