Simply offering high salaries is no longer the optimal solution for recruiting and retaining talent. Instead, companies should conscientiously manage their employer brand both internally and externally. This study adopts the perspectives of social identity theory and social exchange theory to explore how employer branding effectively influences employees′ organizational citizenship behavior and to understand the mediating effects of relational psychological contract fulfillment and affective organizational commitment within the model. The study targets full-time employees who have served in the same company for at least 6 months, with a total of 429 valid responses collected through online surveys. Through structural equation modeling (SEM) analysis, the following research findings were obtained: (1) Employer branding significantly and positively influences relational psychological contract fulfillment; (2) Employer branding significantly and positively influences affective organizational commitment; (3) Relational psychological contract fulfillment significantly and positively influences affective organizational commitment; (4) Employer branding does not have a significant impact on organizational citizenship behavior; (5) Relational psychological contract fulfillment significantly and negatively influences organizational citizenship behavior; (6) Affective organizational commitment significantly and positively influences organizational citizenship behavior; (7) Relational psychological contract fulfillment and affective organizational commitment fully mediate the sequence between employer branding and organizational citizenship behavior.
