According to AU (2009) most companies today have a global expansion agenda, and many companies have become multinational or transnational. These companies face the challenge of creating a consistent ethical culture across the global network, while respecting diversity and integrating new values into many different office cultures. A good ethics program is very helpful in communicating the values and visions of a company. Such a program helps create a consistent corporate culture, something that is very important for global companies that have operations in diverse locations with differing legal systems, ethical values, and priorities. An ethics program clearly lays out expectations from employees and helps them make the best decisions. To be effective, an ethics code must have well-conceived and broadly implemented through training and enforcement components. The field of human rights is another important area where companies are placing an increasing amount of attention. A company can avoid human rights violations by creating a code of conduct to be universally applied. A code of conduct sets universal guidelines on various issues like labor, working hours, discrimination, freedom of association, health and safety, and sometimes, environmental practice policies. Another potential problem is corruption and bribery. The U.S. Foreign Corrupt Practices Act prevents companies from paying bribes to foreign governments and officials, as well as political candidates. Also, the organization for economic cooperation and development treaty has members from many countries who have pledged to refrain from unethical behavior.
