Equity Theory, also known as Aams' Equity Theory, attempts to explain relational satisfaction in terms of perceptions of fair/unfair distributions of resources within interpersonal relationships. It was first developed in 1963 by John Stacy Adams, a workplace and behavioral psychologist, who asserted that employees seek to maintain equity between the inputs that they bring to a job and the outcomes that they receive from it against the perceived inputs and outcomes of others (Adams, 1965).
