This thesis analyzes the attitudes of public relations specialists regarding their use of social media in crisis management. The work is divided into two parts – a theoretical and a research part. In the first part, the theoretical framework of public relations, social media, and crisis communication is presented. This section covers the definitions and functions of public relations, the importance of effective communication, and the specific work of public relations agencies. It provides a detailed explanation of the concept of crisis, its causes, and types, the course and development of crises, crisis management, and planning, as well as crisis communication within public relations agencies. Additionally, the main features of social media, their role in crisis situations, user behavior during crises, and the positive and negative aspects of using social media in crisis communication are thoroughly examined. In the second part of the thesis, the research results conducted using the qualitative method of semi-structured interviews are presented. The sample included eight public relations specialists from various agencies. The research results indicate that the majority of respondents have a positive view of social media as a key tool for crisis communication. PR specialists highlighted advantages such as speed, two-way communication, and the ability to timely inform the public. However, they also recognized significant challenges, such as the rapid spread of misinformation, negative comments, and questionable credibility of information. The need for careful communication management and ensuring accuracy and transparency in posts was emphasized. The research demonstrated that although social media are a powerful tool in crisis management, they require a strategic approach and continuous monitoring to maximize their benefits and minimize potential risks. Successfully managing crises through social media can significantly influence public perception and long-term trust in the organization.
