A professional in occupational health psychology works for private or public organizations, many in consulting positions. They can explore how stress affects individuals and recommend stress reduction practices and coping mechanisms, and they change stressful environments through job reorganization. These psychology professionals also work in public health or for private corporations designing and promoting stress prevention policies. Because they are also trained as I/O Psychologists they often work in organizations doing wage and salary administration, human resource development, personnel management, job analysis, quality assurance, selection and placement, and training and development. Research and teaching positions in both OHP and IO are also available at colleges and universities.
