In the current context of sluggish global economic recovery, widening regional disparities, and little room for policy error, the global employment situation is unprecedentedly severe. Therefore, research on sustainable employment is critical. In this study, we utilized a Latent Dirichlet Allocation (LDA) topic modeling approach to identify four central topics within the realm of sustainable employment: “Career Sustainability and Employee Development”, “Socio-Economic Dynamics and Strategies for Sustainable Employment”, “Study on Age, Health, and Sustainable Workforce in the Labor Market”, and “Research on the Impact of Workplace Interventions and Psychological Health Support”. The findings revealed the multidimensional, complex nature of sustainable employment issues. This study expands the theoretical horizon of sustainable employment and proposes multidimensional strategic suggestions for practical applications, including regularly assessing and updating organizations’ leadership styles and employee development strategies, offering customized career development programs and skill training, and formulating inclusive employment policies and supportive workplace environments in order to enhance employee job satisfaction and overall well-being, thereby effectively improving the practical outcomes of sustainable employment and bringing about long-term stability and positive impacts on the labor market. These results provide essential theoretical and practical contributions for policymakers, organizational leaders, and anyone seeking sustainable employment.
