When Coaching Meets Toxicity: Building Internal Coaching Capacity to Sustain Performance Under Destructive Leadership

Abstract: Organizations increasingly invest in internal coaching—structured, peer-delivered development conducted by coaches who belong to the same organization as the coachee—to drive employee learning and performance. Yet emerging evidence suggests that the returns on this investment are not uniform: the leadership climate in which coaching takes place can amplify or attenuate its benefits. This article synthesizes recent research, including a 2026 empirical study of 313 employees in Portuguese organizations, which found that perceived internal coaching positively predicted perceived job performance but that toxic leadership significantly weakened this relationship. The article defines internal coaching and toxic leadership for practitioner audiences, examines their organizational and individual consequences, and presents evidence-based interventions—spanning ethical leadership development, psychological safety architecture, coaching governance, and accountability systems—with illustrative examples from Google, Microsoft, and Intel. Three forward-looking pillars for long-term resilience are proposed: psychological contract recalibration, distributed leadership structures, and continuous learning ecosystems. Practitioners are encouraged to treat internal coaching not as an isolated program but as one element within a broader organizational development strategy that must address both the enabling and constraining forces shaping employee performance.
