What does profess and kin mean?

profess. & kin.--PROFESSIONAL AND KINDRED OCCUPATIONS: This designation includes occupations requiring extensive study or experience in professions, technical services, sciences, art, and related types of work. The preparation for these occupations (with certain exceptions, such as occur in art and literature) is typically acquired through university, college, and technical institute training; experience providing institute training; experience providing equivalent backgrounds; or some combination of these. The functions of these occupations are predominantly mental rather than manual. This designation includes only occupations which cross industrial designation lines or which by the nature of the jobs cannot be identified as belonging to any one industry.
