in industrial and organizational psychology, a model proposing that (a) people are attracted to organizations that hold values that are congruent with their personalities, values, and needs- (b) the organization, in turn, usually employs people with attributes that fit the organizational culture- and (c) those employees who do not fit the organizational culture leave naturally over time. The characteristics of the people who work at the organization become increasingly homogeneous as the result of this process. [proposed by U.S. organizational psychologist Benjamin Schneider (1938- ) in 1987|
