Effort-Reward Imbalance and Occupational Health
Summary
The effort-reward imbalance model posits that work stress arises when the efforts expended by employees exceed the rewards received, whether financial, social or career-related. This sustained mismatch triggers physiological stress responses—alterations in cardiovascular, endocrine and immune function—and heightens risk for a spectrum of adverse outcomes including depressive disorders, burnout, musculoskeletal pain and impaired coronary microvascular function. Overcommitment, an intrinsic tendency to invest excessive personal resources, amplifies vulnerability by undermining recovery. Integrative research has linked imbalance and overcommitment to both objective biomarkers and self-reported health deficits across sectors such as healthcare, emergency services and professional occupations. By capturing the interplay of external demands and internal coping, the model offers a robust framework for assessing occupational stress and guiding interventions. Practical applications range from organisational policies that enhance recognition and reward to leadership practices that promote work engagement, demonstrating global relevance in efforts to protect worker health and wellbeing.

The graph below shows the total number of articles in effort-reward imbalance and occupational health across all publications each year (not limited to Nature Index journals).
Technical terms
Effort-Reward Imbalance (ERI): A model of work stress defined by the ratio of job efforts to the rewards received, where a ratio above unity indicates imbalance.
Overcommitment: An intrinsic coping style characterised by excessive dedication and inability to withdraw from work obligations.
Work Engagement: A positive, work-related state of mind marked by vigour (high energy), dedication (sense of significance) and absorption (full concentration).
