The article is devoted to the analysis of the mechanisms of trade union information dissemination in modern digitalization conditions. The authors give an overview of the latest research on the transformation processes taking place in trade union organizations, including those, working in the domestic higher education system, and also provide data from their own empirical research conducted in the fall of 2023 among the members of the Samara University workers' union. The performed research, based on the data of the questionnaire survey of the university trade union ordinary members (N=107) and semi-formalized interviews with the chairmen of trade union bureaus (N=10), made it possible to analyze the way the university employees assess the quality of the Samara University trade union information work. Conclusions are drawn about the main existing information sources for the trade union ordinary members about its activities, the employees' preferences in the used information channels and the assessment of its reliability, as well as the greater need to obtain information on the protection of labor rights, improvement of working conditions and the collective agreement management. Based on the study results, practical recommendations are formulated for the trade union committee on improving the effectiveness of information work and operational feedback between the trade union leadership and its ordinary members.
