The main objective of this study is to explore how school culture affects teachers’ decisions to remain in their jobs and their overall job satisfaction. A mixed-methods research design was employed. Surveys were used to collect quantitative data on teachers’ demographics, perceptions of school culture, job satisfaction, and retention. In addition, interviews and focus group discussions were conducted to gain deeper insights into teachers’ personal experiences and perceptions of how school culture influences their satisfaction and decision to stay. The study was conducted in six public secondary schools in Banga, Aklan, involving 112 teachers selected through stratified random sampling to ensure representation from each school. The findings conclude that a positive school culture—characterized by support, effective leadership, collaboration, and opportunities for professional growth—contributes to improved teacher retention and job satisfaction. However, its statistical impact is not particularly strong, indicating that other factors also influence these outcomes. Perceptions of school culture’s influence were consistent across all demographic groups. The study underscores the importance of a collaborative approach in cultivating a positive school culture. Students, teachers, parents, and school leaders all play vital roles in creating a supportive environment through mutual respect, ongoing professional development, open communication, and strong community engagement. Ultimately, fostering a healthy school culture leads to a more stable, motivated, and effective teaching workforce.
