Melissa is the HR manager at a multinational corporation. She is currently developing a new code of conduct for the company, which will be applied across all global offices. Melissa wants to ensure that the code of conduct reflects values that are universally accepted and necessary for the ethical functioning of the corporation in different cultural contexts. What principle should guide Melissa's development of the company's code of conduct to ensure it is effective across diverse cultural environments? O Existentialism, encouraging employees to create their own individual values and standards of conduct based on personal beliefs. O Egoism, focusing on values that promote the company's self-interest and competitive advantage over ethical considerations. O Universalism, which states that all people should uphold certain values that society needs to function, guiding Melissa to include values such as integrity, respect, and fairness in the code of conduct. O Relativism, suggesting that Melissa should tailor the code of conduct differently for each cultural context without universal standards.
