A public service or service of general (economic) interest is any service intended to address specific needs pertaining to the aggregate members of a community. Public services are available to people within a government jurisdiction as provided directly through public sector agencies or via public financing to private businesses or voluntary organizations (or even as provided by family households, though terminology may differ depending on context). Other public services are undertaken on behalf of a government's residents or in the interest of its citizens.

Government employees Government agencies are not profit-oriented and their employees are often motivated differently. Studies of their work have found contrasting results including both higher levels of effort and fewer hours of work. A survey in the UK found that private sector hiring managers do not credit government experience as much as private sector experience. Public workers tend to make less in wages when adjusting for education, although that difference is reduced when benefits and hours are included. Public servants have other intangible benefits such as increased job security and high wages. Need satisfaction and sustainability A study concluded that public services are associated with higher human need satisfaction and lower energy requirements while contemporary forms of economic growth are linked with the opposite. Authors find that the contemporary economic system is structurally misaligned with goals of sustainable development and that
