The volume describes the PSC (public service careers) program created to secure, within the merit principle, permanent employment for the disadvantaged in public services agencies, stimulating the upgrade of current employees, and thereby meeting public sector needs. PSC aims to attack institutional and individual barriers to promote the most effective use of human resources; including outmoded job structures, inadequate recruitment, etc. Barriers considered in the individual include inadequate education, lack of necessary vocational skills, poor orientation to the world of work, medical, transportation, and child care problems. Four major strategies of PSC are outlined. The volume should be of value to potential sponsors for upgrading in the public sector. (Author)
