The study presents the examples of this distinction in the analysis of the expert and advisory roles, sales, negotiations and organizing in typical situations of management. Based on these examples, the text specifies the conception of rational and irrational informative assertiveness and their roles in management. The objectives were realized using the phenomenological analysis and the case study. The study formulates hypotheses and shows the perspective of further research on the impact of rational and irrational informative assertiveness on management processes.
