概述：This lecture aims to talk something about ethics in companies.
Now, I will move on to discuss the main issue of making companies turn to ethics for competitive advantage. By setting themselves up as ethical, however, companies are not so much promoting the importance of ethical conduct, the well-being of the local community or the development of society as a whole, as engaging in powerful marketing to attract both discerning clients and bright young recruits. In today's markets, any company without a coherent ethics policy is in danger of surrendering a competitive advantage to its rivals. In order to develop an ethical code of conduct, companies will have to deal with issues such as the legal implications of their disciplinary measures and the effect any new procedures will have on employees. However, new policies can only be developed once the company has identified the core values that underpin its day to day operations. Without a clear understanding of these values, it is impossible to develop a code of conduct compatible with the company's culture. An effective code will dictate how employees approach conflicts and other stressful dilemmas not covered by the normal terms and conditions of employment. It will provide employees with a clear understanding of what behavior is expected when they find themselves confronted with such dilemmas.
