This article concentrates on extending a theoretical framework by exploring employees’ willingness to report unethical issues under the effects of ethical leadership, public service motivation, peer relationship, affective commitment, and fairness. By using structural equation modeling to analyze data collection from 320 public servants in Ho Chi Minh City, Vietnam, the results demonstrate that all the mentioned factors are positively correlated with willingness to report unethical issues in the context of the public sector, except for public service motivation. The findings open a potential path for future investigation of affective commitment and fairness as mediators that help to stimulate the behavioral reports of misconduct at workplaces. The new findings expand the literature in the public sector and suggest possible solutions to promote an energetically ethical environment.
