With an analysis of human work behavior, this text addresses the issues of using psychology at work. A focus on the development of employees and organizational structure helps students understand how psychology is applied in the workplace. Organizational psychology is discussed as an area of I/O that focuses on social behavior, including the management of work groups and organizations. Students are presented with strategies for solving the human problems of work that result from environmental, technological, and social factors. Unlike other texts available for the I/O course, this book features thorough coverage of the field and applications, with pedagogical features to help the student understand more difficult concepts and provide a solid grounding for further study. The instructors will appreciate the research methods chapter.
