Abstract：The exploitative leadership in the organization is very harmful for employees and requires intervention management. Drawing on the fairness heuristic theory, the study researches the conditional process between exploitative leadership and employee creative territorial behavior based on the longitudinal data collected from 403 employees. Results show that: exploitative leadership significantly affects employee creative territorial behavior; psychological contract breach mediates the relationship between exploitative leadership and employee creative territorial behavior; coworker idiosyncratic deals positively regulates the relationship between exploitative leadership and psychological contract breach, psychological contract breach and employee creative territorial behavior, the higher the degree of coworker idiosyncratic deals, the stronger the corresponding relationship; coworker idiosyncratic deals positively regulates the indirect process of the influence of exploitative leadership on employee creative territorial behavior, the higher the degree of coworker idiosyncratic deals, the stronger the mediating effect of psychological contract breach.
