Life without communication is unimaginable, it surrounds us in all spheres of life. Whether it is a personal life or a professional life, the process of communication is inevitable. There are very large number of definitions of communication, but all of them have in common that communication is the process of exchanging information between sender and receiver. Each communication consists of elements: sender, receiver, encoding, communication channel, decoding and feedback. Communication participants may or may not be aware of the existence of these elements. Business communication is communication that takes place in the economic sphere. It can take various forms, from oral, written, electronic, and even nonverbal. The communication culture within an organization has a major impact on its market success. Without timely, accurate and complete information, an organization cannot operate. Communication within organizations is mostly of a formal form, but the impact of informal communication should not be overlooked. Given that community organizations are people with different attitudes, views and beliefs, conflict is to be expected. Conflict is a situation when two opposing opinions arise. Not every conflict has to be bad, but it is important to recognize the boundaries of constructive and destructive conflict. Regardless of who the participants in the communication are, it is necessary to respect the minimum legal norms of behavior. The empirical part of the paper examines the functioning of business communication at the Croatian National Theater in Split. 64 respondents participated in the study. All research participants believe that communication is important for business and most of them are satisfied with communication at work. Oral communication is most commonly used, but they prefer to use electronic communication to send and receive important information. Sometimes there are conflict situations at work, and the biggest reason for that is the lack of communication. Listening is considered as important as speaking, and most people think that their colleagues listen to them enough.
