In this paper, I describe in detail the communication in private sector. Processes and Relations in Communication. The difference between everyday communication and business communication. The question is whether it is more efficient for a company to set up one person as a director and manager in one person or to have a manager how is a trained leader. In a business meeting all participants creates a first impression of new partners that will certainly impact on business success. Good communication skills are essential to keep the enterprise in an undisturbed communication flow. Managers lead vertical and horizontal communications depending on the company's communications network. The drive of the manager to the information flow is different in each network. Every communication is subjected to certain disturbances called noise in the channel. We differentiate between verbal and nonverbal communication, man communicates and when he is silent, various gestures and mimics "speak". The culture of communication dates back to prehistoric times and we have a variety of evidence in the form of drawings in caves. The great influence on our communication and our ability to communicate has emotions. Control, i.e., self-control is a major factor for successful managers. In Plutchik's “Whell of wmotions”, basic emotions are shown and their development in stronger and weaker emotions.
