Teaching is often regarded as one of the noblest professions, as it nurtures the minds and characters of the next generation of leaders and thinkers. Therefore, prioritizing the welfare of teachers is equally important to ensure they continue to be efficient in their profession. Teacher well-being is crucial for effective teaching and learning outcomes. A psychologically safe environment built on trust, respect, and open communication empowers teachers, positively impacting their growth and well-being. However, factors like heavy workloads, lack of support, and poor work–life balance can negatively impact teacher well-being, leading to burnout, stress, decreased job satisfaction, and, ultimately, attrition. Quiet quitting, characterized by intentional disengagement and reduced performance, is a concerning trend that may arise from these factors. To address these issues, it is essential to prioritize teacher well-being by creating supportive school environments, reducing workload, providing adequate resources, and fostering a culture of respect and appreciation. This review of literature reveals critical implications for the complex relationship between psychological safety, well-being, and quiet quitting, aimed at implementing effective strategies to enhance the working conditions of Filipino teachers and ensure quality education.
