Work occupies a pivotal role in the daily activities and over the course of a lifetime of members of modern societies. In anticipation, work influ ences education and training; it has much to do with shaping current earned income and status in the community; and in retrospect, it influ ences retirement income and activities. It is a powerful force affecting personal associations. In our society work is deeply encased in moral and religious values: As Poor Richard says, A Life of Leisure and a Life of Laziness are two Things.

Study to show thyself approved unto God a workman that needeth not to be ashamed. But few words have as many different meanings and nuances as "work": to forge or to shape, to stir or to knead, to solve, to exploit, to practice trickery for some end, to excite or to provoke, to persuade or to influence, to toil, and the like.
