The voices from employees have become important information for the stable and innovative development of the organization. The rejection of employee advice is a common phenomenon in reality. The leader's voice rejection, choice of silence, or failure to respond can all be considered as social exclusion. The theory of social exclusion can provide a good theoretical basis for us to understand the motivation of employees' behavior after the leader's voice rejection. The temporal need threat model proposed by Williams on the basis of a large number of experiments is a mature and widely applicable theoretical model in the theory of social exclusion. This study takes refusal as an independent rejection event, and builds a theoretical model of leadership refusal to influence employee behavior motivation under the temporal need threat model. We find how negative emotions and need threats caused by repulsive behavior affect employees'  behavior motivations under different personal characteristics and situational factors. By clarifying the relevant factors and behavioral results that affect the behavioral motivation of employees, this study enriches the related research on admonition response, and provides a realistic reference for the organization to obtain long-term and continuous employee admonition.
