Introduction Philosophy is broadly used for interpreting every area of human interactions and development. Spheres of professional and business relations are not exceptions to the overall trend. There are numerous philosophical approaches, which might be deployed to analyze these fields of interactions. Each popular theory might be beneficial for the better apprehension of business and professional development. Nevertheless, this paper will focus on studying utilitarianism. The motivation for choosing this philosophy is its popularity among the majority of the representatives of the English-speaking world and its focus on happiness. The primary objective of the project is to investigate the aspects of this philosophical approach applied to ethics and use it for analyzing real-life examples of actors operating in professional and business environments. It is another reason for selecting utilitarianism: assessing companies and studying real-world illustrations from the perspective of making people happy is challenging but, at the same time, appealing. Utilitarianism as an Ethical Theory Utilitarianism had philosophical roots before it evolved into ethical theory. In philosophy, it refers to analyzing situations or cases from the perspective of the maximum utility. It means that the emphasis is made on evaluating what benefits a group of people under consideration the most. When the theory was transferred to the field of ethics, the emphasis shifted to measuring happiness. This step was taken by Jeremy Bentham and John Stuart Mill, who are the first representatives of classical utilitarianism. They claimed that assessing potential consequences of actions should be the only guide when making vital decisions. In addition to it, the authors propose to consider justice and beneficence as well as recognize the fact that no decision or action could be seen as a minor one because the aftermaths of all activities and decisions are of the same significance (Hales 1608). In ethics, the postulates of utilitarianism focus on maximizing happiness and minimizing unhappiness. It means that every activity or situation is judged based on how many people were made happier or unhappier because of it. The extent of happiness and unhappiness is used for determining whether to consider the decision right or wrong. Situation or activity refers to laws, social institutions, social relations, public policies, morality, etc. There are several ethical pillars of utilitarianism. The foundation of the theory is John Mill’s standard of morals. Its primary idea is classifying actions and decisions as right or wrong based on the possibility that they will lead to pleasure or pain. If positive consequences outweigh negative ones, i.e. more people are made happy than unhappy, than activity is the right one. Otherwise, it is believed to be the wrong one (West 10). The second pillar of utilitarianism is the belief in the importance of keeping in mind the interests of everyone, who will be influenced by an individual’s (company’s or country’s) decisions instead of being egotistical and seeing personal benefit as the primary priority in life (Velasquez et al. par. 10). That said, utilitarianism preaches
