Background: Peer-support specialists—individuals with diagnosed mental illnesses who provide support services to other adults with diagnosed mental health issues—often feel stigmatized and undervalued at work, leading to negative personal- and job-related outcomes. Given their important link to positive service user outcomes, this study assessed how peer-support specialists perceive fairness and feel valued in the workplace. Methods: Peer-support specialists ( N = 274) were recruited online from peer-support specialist listservs, social media groups, and patient-run organizations to take a cross-sectional survey that included a 14-item scale on how workplace fairness relates to job satisfaction and four questions on how valued they felt by administrators, clinicians, the people they serve, and fellow peer-support specialists. Descriptive and bivariate statistics were used to assess total scores and differences by gender and race. Findings: Ranging in age from 20 to 77 years and identifying predominantly as White (81.0%) and female (62.9%), respondents noted that fair practices in the workplace would increase their job satisfaction, with no significant differences observed by gender or race. Most peer-support specialists felt valued by the people they serve (97.1%) and fellow peer-support specialists (92.7%). However, fewer reported feeling valued by administrators (64.6%) and clinicians (60.6%). Conclusions/Application to Practice: Peer-support specialists value fairness at the workplace and feel undervalued by some staff. This study highlights peer-support specialists’ important role in behavioral health services and suggests that healthcare professionals, including occupational health specialists, are important stakeholders in creating fairer workplaces and increasing peer-support specialists’ sense of being valued, leading to improved personal and organizational outcomes.
