Abstract
<p>The U.S. service industry employs nearly 17 million people and is disproportionately populated by individuals with histories of early adversity, yet no single framework connects the scattered evidence on this workforce across occupational health psychology, trauma psychology, labor economics, and addiction research. This paper advances the Occupational Trauma Compounding Model (OTCM), an integrative theoretical account arguing that the industry structurally selects for trauma-exposed workers and then compounds psychological harm through occupational, physiological, and legal mechanisms, with a distinct symptom picture that persists after workers exit. The model is organized across four levels: (1) structural and psychological selection; (2) occupational entrenchment through trauma bonding, coworker identity fusion, harassment and violence, and the legal exploitation of salaried managers; (3) physiological compounding via substance use, sleep disruption, and nutritional deficiency; and (4) post-industry sequelae that existing diagnostic frameworks systematically misclassify. The paper situates the model against the dominant occupational-stress frameworks — job demands–resources, demand–control, and effort–reward imbalance — and against the burnout construct, arguing that the OTCM adds a selection layer beneath them, an attachment mechanism within them, and a persistence claim beyond them. Synthesizing evidence across published literatures and national datasets, the paper specifies twelve falsifiable propositions and the study designs that would test them, addresses the central identification problem of separating selection from causation, and outlines clinical and policy implications. Primary survey data collection is underway. The OTCM is offered as a testable research agenda for an under-recognized population.</p>
