Venture Challenge - to instill ethical behavior

I believe ethical business only existing in a company with all ethical employees. As long as managers and employees are ethical, venture will be on good shape. So first of all, I believe to hire only ethical persons is essential. Second, venture needs to keep track of ethical culture as an on-going behavior. Third, we need to encourge anyone who see any unethical activity to report to upper management without worry about being punishment or revenge. Last but not least, for all decisions made in company, venture should listen to everyone's voice carefully and most likely lower level non-management employees tend to see unethical behavior in company and their opinions are so important.
