In this study we examine accounting professionals’ evaluations of unethical situations within the philosophical beliefs of justice, deontology, utilitarianism, relativism, egoism, and compassion and the intention to blow the whistle on wrongdoing. We also examine the effects of anonymity, job satisfaction, perceived ethics code enforcement, and organizational commitment on the intention to blow the whistle. This study finds that accounting professionals are able to recognize unethical actions and that they are more likely to blow the whistle on situations involving higher materiality levels when they are guaranteed their job and assured of anonymity. We find that job satisfaction, organizational commitment, perceptions of ethical values, and perceptions of an enforced ethics code are not significant factors in the whistleblowing intentions for this sample of practicing management accountants.
