Safety behaviors constitute a critical determinant of accident prevention in the construction industry. In high-deman‎d environments such as underground metro construction sites, job stress may compromise workers’ cognitive focus an‎d compliance with safety procedures. Despite the recognized importance of this issue, empirical field-based evidence regarding the association between job stress an‎d safety behaviors in high-risk infrastructure projects (e.g., metro stations) remains limited. Furthermore, prior research has predominantly relied on self-reported measures of safety behaviors, with scarce utilization of direct observational methods in real-world settings. This study aimed to investigate the relationship between job stress an‎d safety behaviors among workers at a metro station construction site, while also providing an objective assessment of safety behaviors through systematic field observation. A descriptive–correlational, cross-sectional field-based case study design was employed. Data were collected directly from the project site in addition to relevant documentary sources. The study population comprised 100 workers from diverse occupational categories. Safety behaviors were eva‎luated using structured on-site observations based on a Safety Behavior Inspection Checklist an‎d quantified on a 0–100 scale. Job stress was assessed using a 25-item instrument rated on a five-point Likert scale across seven subdimensions. Statistical analyses included descriptive statistics, Pearson correlation coefficients, an‎d multiple linear regression, conducted using SPSS. Results indicated that poor physical working conditions an‎d excessive workload emerged as the most prominent stressors, whereas role ambiguity showed the lowest mean score. A statistically significant moderate negative correlation was observed between job stress an‎d safety behaviors (r = −0.331, p < 0.001). Multiple regression analysis demonstrated that job stress an‎d accident history jointly accounted for approximately 15% of the variance in safety behaviors. Notably, contrary to findings reported in previous literature, role ambiguity exhibited a significant positive association with safety behaviors. These findings underscore the importance of managing workplace stressors (particularly physical site conditions an‎d workload) to enhance safety performance in underground metro projects. Additionally, accident history may serve as a meaningful predictor in worker safety surveillance systems. Accordingly, implementation of structured safety interventions is recommended, including targeted safety training, stress management programs, strengthened warning systems, an‎d improved feedback an‎d incentive mechanisms to promote safety behaviors.
