Final answer:
The statement that organizational citizenship behavior is motivated more by extrinsic than intrinsic rewards is false. Intrinsic motivation is key to OCB and can be diminished by extrinsic rewards, a concept known as the overjustification effect.
Step-by-step explanation:
Organizational Citizenship Behavior (OCB) is generally perceived as being more motivated by intrinsic rewards than by extrinsic rewards. The statement posed in the question suggests that OCB is motivated more by extrinsic rewards, such as money, than intrinsic rewards, which come from within the individual. However, numerous studies including those by Deci (1972), Deci, Koestner, & Ryan (1999) have highlighted the overjustification effect, wherein offering extrinsic rewards for behaviors that an individual already finds intrinsically rewarding can lead to a diminishing of the intrinsic motivation.
Take for example Odessa, who enjoys baking. When baking became her job, and thus was given extrinsic reward, she lost her intrinsic motivation to bake in her free time. This exemplifies a key concept in organizational behavior: intrinsic motivation can decrease when overshadowed by extrinsic motivators, particularly if those rewards are expected rather than surprising.
Therefore, the statement "In general, organizational citizenship behaviour is motivated more by extrinsic rewards than intrinsic rewards" is false.
