This thesis addresses the role of negotiator types in the selection of negotiation strategies in business negotiations. It examines the business negotiation process, highlighting its crucial role in achieving success. The negotiation process consists of several stages: preparation, proposal presentation, listening, discussion, bargaining, and reaching an agreement. Negotiation skills are essential in a business environment as they significantly contribute to achieving goals. Important skills include problem analysis, careful preparation, emotional control, effective communication, teamwork, and social skills. A properly chosen strategy facilitates the negotiation process and thus increases the chances of achieving goals and the overall satisfaction of all parties involved in the negotiations. There are different negotiation strategies, such as "hard" negotiation, positional negotiation, "soft" negotiation, phantom negotiation, and principled negotiation, with the latter being the only one that aims for a comprehensive solution for both negotiating parties. Negotiators can be categorized into various types, such as dominant, extroverted, introverted, actors, innocents, philosophers, and guardians. In the research part of the thesis, three hypotheses were tested. The first hypothesis, that negotiators primarily choose a strategy based on previous experiences, was confirmed. The second hypothesis, that the "hard" strategy is most often used by dominant types of negotiators, was partially confirmed. The third hypothesis, that the "soft" strategy is most often used by guardian negotiators, was also partially confirmed. The research results show that different types of negotiators use different strategies in different negotiation situations. Experience and communication skills are highlighted as key to achieving success in negotiations.
