This study analyzed the social media communication of six higher education institutions (HEIs) in Poland during the COVID-19 pandemic within the context of university social responsibility (USR). The study used a mixed-method approach, conducting both quantitative and qualitative analyses of 5547 social media posts published by HEIs on their official Facebook, Instagram, Twitter, and YouTube accounts. The analysis identified three rhetorical strategies that were used by HEIs during the pandemic: Business as Usual, We are Great!, and We are Together. The study found that when compared to posts not related to COVID-19, the posts concerning the pandemic achieved higher interaction and broader reach on social media platforms. Facebook and Twitter emerged as the most frequently utilized platforms for crisis communication. This study thus underscores the role of social media as a vital tool for HEIs to use to fulfill their USR by actively engaging with stakeholders and fostering community solidarity and education during crises. The findings also advocate for using HEIs to harness social media not merely for information dissemination, but also as a platform for active stakeholder engagement and community support, both integral to their social responsibilities during challenging times.
