From wikipedia:
Industrial and organisational psychology (also known as I-O psychology or work psychology) is the scientific study of employees, workplaces, and organizations. Industrial and organizational psychologists contribute to an organization's success by improving the performance, satisfaction, and well-being of its employees. An I-O psychologist conducts research on employee behaviors and attitudes, and how these can be improved through hiring practices, training programs, feedback, and management systems.[1] I-O psychologists also help organizations transition among periods of change and development. Industrial and organizational psychology is related to organizational behavior and human capital.
