Internal communication is the exchange of opinions and ideas of employees in a company. Depending on the direction in which this communication is conducted, internal communication can be downward, upward, and horizontal. One of the functions of internal communication is the motivation of employees. Motivation can be defined as a psychological process that motivates an individual to mental or physical activity and acts „on the inside” for individual behavior. Internal communication is transmitted information that is essential to the company and is provided employees with feedback on how they have done their job. If employees are successfully involved in internal communication, if they are accurately aware of their tasks and the meaning of their successful performance, if they are commended for successful work and if their less successful work is criticized solely in a constructive manner, employees will be motivated to work. The paper presents the results of the research which investigated the impact of internal communication on motivation of employees on the example of INNOVATIO PROFICIT d.o.o. Whose core activity is computer programming. Specifically, for research purposes was created a questionnaire. The research was attended by 15 employees of INNOVATIO PROFICIT d.o.o. The results of the research have shown that the employees of this company are mostly satisfied with internal communication in that company and that internal communication in that company has a positive impact on the employee's motivational motivation.
