Human Resources, Training, and Labor Relations Managers and Specialists
Education and training. Although a bachelor’s degree is a typical path of entry into these occupations, many colleges and universities do not offer degree programs in personnel administration, human resources, or labor relations until the graduate degree level. However, many offer individual courses in these subjects at the undergraduate level in addition to concentrations in human resources administration or human resources management, training and development, organizational development, and compensation and benefits.
Because an interdisciplinary background is appropriate in this field, a combination of courses in the social sciences, business administration, and behavioral sciences is useful. Some jobs may require more technical or specialized backgrounds in engineering, science, finance, or law. Most prospective human resources specialists should take courses in principles of management, organizational structure, and industrial psychology; however, courses in accounting or finance are becoming increasingly important. Courses in labor law, collective bargaining, labor economics, and labor history also provide a valuable background for the prospective labor relations specialist. As in many other fields, knowledge of computers and information systems is useful.
