The document discusses several reasons for unethical behavior in companies, even when managers intend to run ethical organizations. Specifically, it notes that employees may bend or break ethics rules when leaders are blind to issues or encourage unethical behavior unintentionally, such as through ill-conceived goals or incentives. The document also suggests companies often overlook issues in other companies they do business with or fail to notice the gradual erosion of ethical standards over time. However, companies can improve their ethicality by installing codes of ethics, providing ethics training for employees, and being responsive when values are violated.
