According to the school of ethical universalism,
A. all societies and countries are obligated to apply universally defined ethical principles of right and wrong as set forth in the Global Code of Ethical and Social Morality (which is subscribed to by 150 nations of the world).
B. universal ethical principles or norms put limits on what actions and behaviors fall inside the boundaries of what is right and which ones fall outside; such universal norms include honesty, trustworthiness, respecting the rights of others, practicing the Golden Rule, and avoiding unnecessary harm to workers or to the users of the company's product or service.
C. the standards of what constitutes ethical and unethical behavior in business situations are partly universal, but in the main are governed by local business norms.
D. it is only fair that the standards of what's ethical and what's unethical be applied universally to all businesses in all countries irrespective of local business traditions and local business norms.
E. all societies and countries apply essentially the very same set of universally defined ethical principles of right and wrong in judging the ethical correctness of business behavior.

As per the school of ethical universalism, there exists a common ethical framework employed by all nations which govern what is right or wrong, irrespective of diverse cultures and religion, which depicts existence of a common moral agreement between nations.

The purpose here being, such common ethical standards can be applied to judge the ethical conduct of employees working at multi national companies, operating in different countries.

For e.g, deception or fraud would be unacceptable in corporates operating in any part of the world, since universal ethical principles, common to all and which govern employees conduct, oppose them.

So irrespective of which part of the world a company operates or the regional culture of the respective nations, virtues such as honesty, truthfulness shall always be appreciated while treachery, malevolence, deceit will always be unacceptable.
