This study explored the link between interpersonal relationships, managerial competence, and job satisfaction among one hundred fifty eight teachers selected through purposive random sampling. Using a quantitative-correlational design, it found that strong interpersonal bonds particularly commitment and effective managerial skills especially problem-solving significantly predict higher job satisfaction. Teachers reported high levels of both interpersonal relationships and managerial competence, with communication and supervisor management being key contributors to satisfaction. While most job satisfaction factors scored moderately to high, benefits and rewards showed room for improvement. The findings highlight the need for school leaders to enhance teamwork, leadership skills, and recognition systems, while addressing compensation concerns to support teacher well-being and retention.
