Configurational dynamics and structural mediators of psychosocial attrition in contemporary labor ecosystems

Within the volatile landscape of the Fourth Industrial Revolution, pervasive occupational precarity has emerged as a critical systemic stressor, catalyzed by the rapid onset of autonomous systems and macro-economic restructuring. While the deleterious effects on physiological and psychological well-being are documented, the underlying mechanisms and nonlinear thresholds through which insecurity erodes institutional vitality remain theoretically fragmented. Using a diverse, multi-sectoral cohort (N = 874), this study employs a sophisticated methodological nexus, integrating Structural Equation Modelling (SEM), fuzzy set Qualitative Comparative Analysis (fsQCA), Necessary Condition Analysis (NCA), and Multilevel Modelling (MLM) to map the multidimensional architecture of psychosocial attrition. Our findings establish that job instability functions as a potent driver of direct and mediated declines in psychosomatic equilibrium, exacerbated by fractured communication channels and heightened organizational threat perceptions. Specifically, the application of NCA identifies precise critical insecurity thresholds (3.1–3.3) that serve as tipping points for health degradation, while fsQCA reveals diverse equifinal pathways to employee vulnerability. By synthesizing these advanced analytical frameworks, this research positions job insecurity not merely as a localized concern but as a fundamental structural health hazard. Consequently, we advocate for the institutionalization of proactive monitoring infrastructures and high-fidelity early warning systems to safeguard the long-term sustainability of human capital.
