Taiwan's industrial structure is mainly composed of small and medium-sized enterprises (SMEs), with over 98% of enterprises being SMEs and employing more than 80% of the workforce in Taiwan. Many industries are under severe stress due to the COVID-19 outbreak, and many companies are reducing staff hiring or staff working hours. The main purpose of this study was to examine the factors influencing the job well-being of Taiwanese SME employees in the context of the COVID-19 epidemic, including organizational justice, job insecurity, decent work, and organizational commitment. Through a questionnaire survey, 653 valid questionnaires were collected and analyzed using structural equation modeling to verify the effects between the study constructs. The study found that organizational justice, job insecurity, and decent work all had significant effects on organizational commitment, with job insecurity having the least effect. Organizational commitment has a positive and significant effect on employees' job well-being, with a standardized regression coefficient of 0.469. In the research model, the R2 of employees' organizational justice, job insecurity, decent work, and organizational commitment on job well-being was as high as 0.724. The results of the study show that Taiwan has a large number of SMEs that can respond quickly and flexibly to the environment. Even in the unsettled environment of an epidemic, employees' organizational commitment to the company remains a decisive factor in employee well-being. The smaller-than-expected impact of employee job insecurity is indirect evidence of the resilience of the Taiwanese industry.
