Abstract

Nowadays, with the popularity of social media, information shifted from the previous crisis dissemination method to a more complex and rapid online spread. Public sentiment had a greater impact on shaping corporate reputation and market results. This study examines how social media emotions spread on the Internet and influence public perception during corporate crises and conducts a comparative analysis using two different cases. Due to data access restrictions, this article presents an analysis of manually collected tweet samples: 52 tweets from Starbucks' 2024 union movement and 30 tweets from Tesla's November 2023 vehicle recall. Manually mark the emotions as positive, neutral or negative based on the attitude expressed in the tweet to the company and events. The survey results reveal significant differences: Starbucks' tweets are mainly positive (56%), with strong public support for its workers, while Tesla's discourse on product safety issues is polarized (37% positive, 40% negative). These patterns indicate that labor disputes generate more persistent sympathy, while discussions triggered by product safety crises are more objective and balanced. This research contributes to crisis communication literature by emphasizing the importance of conducting specific analyses based on different types of crises and provides practical significance for enterprises' crisis response strategies and investors' decision-making. The limitations of this paper include a small sample size and the lack of quantitative analysis, which points out the direction for future research on larger datasets.
