Workplace mental health is increasingly recognized as a critical determinant of organizational sustainability and employee well-being. Rising stress, burnout, and mental health challenges have created productivity losses estimated at over one trillion dollars annually worldwide. Despite the growing emphasis on wellness programs, limited research has examined the role of structured mental health audits as a mechanism for monitoring, evaluating, and improving organizational practices. Drawing on knowledge translation and audit-feedback literature, this paper conceptualizes workplace mental health audits as a strategic human resource management tool that links compliance, early risk detection, and employee support systems. We propose a framework integrating audit processes with evidence-based guidelines and employee-centered interventions. A mixed-methods design is suggested to evaluate both organizational readiness and employee perceptions, generating insights into the barriers and facilitators of effective implementation. By positioning mental health audits within broader workplace well-being strategies, this study contributes to the discourse on sustainable HRM and offers practical implications for organizations seeking to foster resilient, healthy workforces.
