Language teachers often face unique challenges in their professions. The advent of Covid-19 created new stressors that teachers had to adapt to in order to persevere. This study examines twelve English language teachers' well-being and perseverance during the Covid–19 pandemic in Sweden. The purpose is to understand how they persevered in the face of adversity. The aim is to understand how the Covid-19 pandemic affected English teachers' working situation and well-being. This qualitative research study seeks to answer the following question: How can we understand the perseverance of English teachers under the Covid-19 pandemic? The data is interpreted and analyzed through the lens of positive psychology, and we used 'EMPATHICS' as our framework. The focus of the study is on Perseverance and its themes of Resilience, Hope, and Optimism. These themes are identified and analyzed through a thematic content analysis which follows an iterative process. The results showed that internal and external factors influenced the teachers' perseverance and ability to create pathways and strategies to handle adversities. In conclusion, teachers persevered by being resilient, hopeful, and optimistic during the pandemic.
