This study investigates the factors influencing turnover and job satisfaction in large corporations in South Korea, using organizational-level data derived from online employee reviews. By analyzing 83 companies across various industries, this research focuses on the roles of Perceived Organizational Support (POS), Career Plateau, and Job Satisfaction, with turnover rates measured at the organizational level through sustainability reports. Unlike prior studies that primarily examine turnover at the individual level or rely on turnover intentions as a proxy, this study uses aggregated metrics and actual voluntary turnover rates to provide a more objective and systemic perspective. The findings reveal that while POS and Career Plateau significantly influence Job Satisfaction, their direct effects on turnover are limited in the context of large corporations. This can be attributed to the unique structural and institutional characteristics of these organizations, such as superior salaries, comprehensive welfare policies, and structured career management systems, which mitigate the impact of POS and Career Plateau on turnover. Instead, Job Satisfaction emerges as a critical mediating variable, reinforcing its central role in turnover dynamics. To analyze the data, this study employed a Word2Vec-based vocabulary dictionary and K-Means clustering to process textual reviews from the Blind platform, followed by Structural Equation Modeling (SEM) to test the relationships among variables. The organizational-level focus of this research offers industry-wide insights, avoiding the limitations of small or homogeneous samples. By integrating computational methods with Social Exchange Theory (SET), this study provides a robust framework for examining turnover and job satisfaction in large organizational contexts, offering practical implications for corporate HR practices and future research directions.
