The technical cooperation work of Human Resources for Health Unit (HSS/HR) is based on the principles underpinning all people's right to enjoy the highest attainable standard of health, and on the principles of equity and solidarity. Human resources for health play a pivotal role in progressively overcoming geographical, economic, sociocultural, organizational, ethnic, and gender barriers so that all communities may have equitable access, without discrimination, to comprehensive health services that are appropriate, timely, and of good quality.  The aim of HSS/HR work is to guide the design of policies on human resources for health, taking into account that the availability, accessibility, relevance, and competencies of health workers are key to achieving universal health and meeting the objectives of the 2030 Agenda for Sustainable Development.
