Communication is one of the reasons for the success of companies. The ability to understand each other during work leads to the creation of favorable working conditions and a working environment. At the same time, it helps to establish good relations between employees. However, communication barriers are emerging in every organization. These barriers prevent effective communication. The main goal of this study is to determine whether the occurrence of communication barriers in the company affects the work performance of employees. To achieve the goal, we will use data obtained from a questionnaire survey. These data were collected from a sample of respondents from the Slovak Republic. The data were processed using MS Excel and IBM SPSS Statistic 25. In our article, we proved that the occurrence of communication barriers in the company does not affect the work commitment of employees.
