Vliv interní digitální komunikace na pracovní výkon zaměstnanců

This bachelor thesis examines the impact of internal digital communication on employee job performance in the Czech work environment, focusing on the role of information and communication overload. The aim of the thesis is to verify the relationships between the frequency of using digital communication tools, information and communication overload, and perceived employee job performance. The research was conducted quantitatively through an online questionnaire survey on a sample of 104 employees. The obtained data were analyzed using correlation and regression analysis. The results showed that a higher frequency of using digital communication tools is significantly associated with a higher level of communication overload, but not with information overload. Simultaneously, it was found that both information and communication overload are negatively related to job performance, with information overload emerging as its most significant predictor.
