Public relations blunders occur when organizations or individuals mishandle communication, leading to negative public perception. These mistakes can arise from poorly timed statements, insensitive comments, or failure to address crises effectively. Such errors can damage reputations and erode trust among stakeholders. Examples of public relations blunders include United Airlines' mishandling of passenger removal in 2017 and Pepsi's controversial advertisement featuring Kendall Jenner. Both instances sparked widespread backlash, highlighting the importance of understanding audience sentiment and the potential consequences of miscommunication in the digital age.
