Abstract:

Workplace bullying is a negative behavior in the workplace and influences the well-being of the bystanders, who are in the same ecosystem with the perpetrator and target. As the third party, bystanders are a heterogeneous group. Some positively intervene by protecting the bullied; some passively encourage bullying by ignoring it. Others may actively encourage bullying by supporting the bully. The roles and behaviors of bystanders will influence the evolution of workplace bullying in turn. Furthermore, bystanders’ behaviors are influenced by their deontic perspective of justice and emotion through social exchange and learning process.

Key words: workplace bullying, bystander, roles, behaviors, influence mechanism
