Rethinking morality in managementscienceWhat is morality in management science? Why does management need to concern moral behavior? Because most management researchers feel whose behaviors are possible right, but in moral view point, whose behaviors are possible wrong. This is a subjective personal moral judgement to management researcher individual behavior in any organization. However, if the management researchers can know how to judge whose behaviors whether ar more moral reasons to be accepted in societies . The, who can judge how to choose to do more right moral behavior more correctly in any organizations.Some management scientists should not assume that one value can be objectively better than another, or that any values are objectively right or objectively wrong. So it brings this question: Are values objective? Are there sometime objective by god reasons to moral actions? Perhaps it is time to rethink hesitation about accepting moral objectivity in management search. Usually management researchers choose to decide to do immoral management behaviors. It is possible that who is seemed to have effort to help whose organization to gain benefits and dominant economy. So, in economic view point, the management researchers are helping their organizations to gain, it is possible that the management researchers do not feel who are doing immoral behaviors to assist their organizational development. Also, even whose behaviors are legal, but it is not represent their behaviors must be morality in societies. Hence, knowing how to judge whether it is moral behaviors, it is important to every management research in nowadays organizational environment. In any organizations, that agency theory fails to predict corporate performance, because of mechanisms of monitoring, independence and incentives ( Dalton et al. 2003: Dalton et al. 1999) . Due to this reason of self-interested, so management level staffs ( researchers) often do immoral behaviors to influence whose whole organizations to bring negative effect to publicity. Because management researchers will feel themselves self-interest is important than whole organizational interest. It is self interested immoral behaviors, although it is not represent themselves behaviors must be illegal in society.However, good explanations of moral / immoral behvior and how management researchers are affected by moral principles are ones that sometimes make use of the objective structure of moral reasoning. This relates to equate what ought to be with what " is". But is is to say that because management researchers think in ways about ethics, those patterns may be revealed in their actual behavior. Take a simple example related the value of fairness, e.g. the management researcher feels unfair compensation or welfare treatment or salary is provided from whose employer. So, it influence who choose to do immoral activities in whose organizations. So, it seems unfairness is a factor to cause management researcher's immoral behavior or the another factor of perhaps management researchers' hesitation to refer to moral principles when explaining behavior is from the assumption that moral reasons or principles can never serve as causal explanations of behavior.Anyway, in any organizations, permission and obligation in ethics necessity and possibility in logic principle is essential to be prohibited to every management researcher behavior. The reason is because just or unjust ( fair or unfair ) behaviors are caused by economical self-interest of human behavior ( management researcher behavior). Also, the prior organizational fair researchers are mostly explored relationships between fair or unfair behaviors in the one hand, and self-seeking motives on the other hand.
