This study aims to analyze the effect of quality of work life and job satisfaction on employee loyalty at The Westin Yilan Resort, a five-star wellness resort located in Yuanshan Township, Yilan County, Taiwan. The hospitality industry is labour intensive and is characterised by shift work, high emotional demands, and a relatively high turnover rate, so that resorts are required to manage their human resources in order to retain employees and build sustainable loyalty. The research employed a quantitative approach using a survey technique, distributing questionnaires to 100 employees of The Westin Yilan Resort selected through accidental sampling across departments, work shifts, and working days. Data were analyzed using multiple linear regression with the SPSS version 25 application, preceded by validity and reliability tests. The results show that quality of work life has a positive and significant partial effect on employee loyalty, and job satisfaction also has a positive and significant partial effect on employee loyalty. Simultaneously, both variables significantly influence employee loyalty, with a coefficient of determination of 0.575, meaning 57.5% of the variation in employee loyalty is explained by quality of work life and job satisfaction. Based on the standardized coefficients, quality of work life (Beta = 0.451) is a more dominant predictor than job satisfaction (Beta = 0.394). These findings confirm that improving the quality of work life while maintaining job satisfaction is the main strategy for strengthening employee loyalty at The Westin Yilan Resort.
