The main goal in this paper is to explore representation and application of mediation in the selected company. Two conflicting parties, in any previous relationship, who cannot settle their dispute and do not want their process to become long, expensive and unresolved, can opt for a conciliation process in which a profesionally trained person meets the conflicting parties and through listening and discussing tries to reconcile them. One of the most suitable places to conduct mediation is the work environment, because the goal in the workplace is to solve the process as quickly, efficiently and cheaply as possible. The subject of the research in this paper is the analysis of the impact of mediators and mediation processes on conflict resolution in the company Hrvatska Pošta, in order to provide insight into the impact of mediation in specific situations where conflicts have occurred. The primary research is based on an in-depth semi-structured interview. In addition to the interview, data collected from the relevant scientific and professional literature were used. A detailed analysis of Hrvatska Pošta concludes that mediation processes usually have a positive outcome and that after the conciliation process, the conflicting parties can continue to cooperate together as before the conflict. The problem is that there is still no clear legislative framework to give the mediation process full legitimacy and legality. The need for mediation processes is constantly growing and mediation as a way of resolving conflicts is becoming more and more widely used, although still insufficiently.
