Abstract: Early career researchers (ECRs) navigate increasingly precarious academic landscapes where professional legitimacy demands extraordinary personal sacrifice. This article examines the toxic culture of overwork that pervades contemporary academia, using autoethnographic reflection and empirical evidence to illuminate how institutional pressures, performance metrics, and implicit norms compel ECRs to prioritize productivity over wellbeing. Drawing on organizational psychology, labor studies, and higher education research, the analysis reveals how the pursuit of being perceived as a "good" academic—characterized by relentless availability, excessive output, and self-exploitation—produces measurable harm to individual health and organizational effectiveness. The article synthesizes evidence-based interventions spanning transparent communication, structural reform, mentorship redesign, and workload governance, while proposing long-term strategies for psychological contract recalibration, distributed leadership, and purpose-driven academic identity formation. The analysis concludes that sustainable academic cultures require fundamental rethinking of excellence beyond productivity metrics.
