Currently, China is in a period of economic and social transformation, and workers fi nd themselves in a social environment characterized by "strong capital, weak labor". The involvement of social work in workers' services, thus, has become a strong supplement to government and corporate efforts. After over 20 years of exploration, corporate social work has developed a stable service model. In this context, this research, using empirical survey data as case studies, analyzes and discusses the role dilemmas faced by social workers in the industrial park, including their roles as supporters, service providers, policy infl uencers, resource integrators, and enablers. The study fi nds that under conditions of low social recognition, high administrative intervention and institutional absence, social workers in the industrial park gradually lose their subjectivity and tend towards instrumental rationality choice. The current research suggests that, to help frontline workers overcome their role dilemmas and move towards professional and authoritative development of services, measures be taken in the following four aspects: building a foundation of trust in services, releasing subjectivity, establishing institutional safeguards, and enhancing organizational capacity.
