Stress in the workplace is commonplace and how employees choose to voice their stress can have an impact on their performance evaluations and their career progression. Employees must successfully navigate workplace dynamics when they choose to voice their stress to their managers. While there is significant research regarding stress and voice in the workplace, little exists about the intersection, voicing stress. This research provides new experimental data and insights to help explain how voicing stress impacts an employee’s performance evaluations. Distinguishing between the concepts of challenge stress, hindrance stress, supportive voice, and challenging voice, this study tests several hypotheses regarding the relationship between voicing stress and performance evaluations. Additionally, several predictions were made about what might mediate the relationship. The findings suggest that how an employee voices various kinds of stress has an impact on an employee’s performance evaluations, perceived effectiveness, and potential for promotion.
