This final explores the interconnection of internal communication with the work pleasure of employees and their loyalty. At the beginning of the paper, the thesis is that there is a positive correlation between internal communication and employee satisfaction and loyalty to the company in which they work. Therefore, in the work itself, through the existing literature, as well as by the data collected by the survey, this thesis was attempted to be confirmed. First of all, the concepts needed to understand the work, such as communication, motivation, job satisfaction, employee loyalty and internal marketing, are defined. Communication has always been an inseparable part of man's existence, so when we talk about entrepreneurship and business in general, the importance of business communication should always be pointed out. Business communication involves interaction between the company and its environment, as well as internal communication, which is also the main part of internal marketing. Internal communication is indispensable for the healthy functioning of the company as well as its success on the external market. Managers who timely and truthfully alert their employees create a working environment that motivates their employees and makes them loyal to the company they work in. Motivation, as a initiator of every human activity, has a significant impact on the fact that employees steer their work towards achieving the company's goals. That is why motivation must be permanent and omnipresent.
