Workplace ostracism is not conducive to the role adaptation and performance improvement of college graduates. Based on the theory of resource preservation and from the perspective of colleagues less researched at the current stage of workplace ostracism, this study explores the impact of coworker ostracism and emotional intelligence on the job performance of new graduates. The results of this study showed that 1) while coworker ostracism negatively affects the task performance and relationship performance of new graduates, 2) emotional intelligence positively affects their task performance and relationship performance, and 3) emotional intelligence negatively regulates the relationship between coworker ostracism and their task performance, i.e., emotional intelligence weakens the negative effect of coworker ostracism on the task performance of recruits.
