Work motivation "is a set of energetic forces that originate both within as well as beyond an individual`s being, to initiate work-related behavior, and to determine its form, direction, intensity, and duration" Understanding what motivates an organization`s employees is central to the study of I–O psychology. Motivation is a person`s internal disposition to be concerned with and approach positive incentives and avoid negative incentives. To further this, an incentive is the anticipated reward or aversive event available in the environment. While motivation can often be used as a tool to help predict behavior, it varies greatly among individuals and must often be combined with ability and environmental factors to actually influence behavior and performance. Because of motivation`s role in influencing workplace behavior and performance, it is key for organizations to understand and to structure the work environment to encourage productive behaviors and discourage those that are unproductive.
