Ethics is derived form the Greek work ‘ethos’ which means a person’s fundamental orientation toward life. Ethics refers to the moral standards used to govern behaviour and to determine right or wrong, good or evil. Ethical behaviour are the acts consistent with the moral standards or codes of conduct established by society. Ethical standards may change over time and differ form culture to culture. For example, political bribes or payoffs may be acceptable in one culture but not in another. Ethical issues are inevitable in business.
