Findings indicated that extrinsic and intrinsic reward system had no direct effect on work satisfaction, leading to the need to evaluate companies' reward systems. Specifically, it concerned intrinsic reward system which seemed to not be perceived as a reward. Reward system was heavily laden with external influences, internal affairs of organizations and the psychology of employees, especially those involving the perception of fairness. Extrinsic rewards were relatively easy measure in a way which could be accepted as fair. But there was no such intrinsic rewards, because the benefits are more abstract, such as autonomy and the completion of the work. Employees at the leadership level, categorized by Vroom as high level employees, which is a relative terms, received extrinsic rewards in the form of financial rewards, interpersonal rewards, promotion, which were seen as the companies' obligations to give to them. But there was no intrinsic reward. This was seen as a company policy to increase motivation, so that the employees could perform optimally. Intrinsic rewards should be developed in accordance with the variations of characteristics associated with work performance.
