Business ethics is a code of conduct which has been mutually accepted by professionals, entrepreneurs and business people the correct way of dealing with people. It is representing the morality which is based on truth and justice therefore it should definitely be used in business. In the business world, ethics is being reflected in performing the set of goals into reality and by which we are responsible to the other party. However it is known that in business almost nothing we do is for the common good but instead we do everything for our personal gain, mostly for profit. Exactly this pursuit and desire for a greater profit obscures the views of managers nowadays so in that manner they tend to forget about the ethics, moral values and norms in business. Many companies are practicing unethical behaviour and are justifying it with numerous excuses that say they just didn't had any other choice and believe that they have the right to apply double standards. In business ethics the „morality of success“ is ruling quite often which means that the most important is success, without taking into consideration the way of achieving it. Therefore, companies that want to act justly are developing a code of ethics which is representing an important first step in introduction of business ethics in the daily business operations. Companies that apply the code of ethics are performing better than those who don’t apply it and points to the fact that the employees who work in companies with developed ethical culture are more loyal and more involved in the company so having this in mind the company comes to achieving greater business success.
