Despite the recognized significance of risk perception and safety interventions in the job environments of frontline workers in the manufacturing industry, there remains a lack of understanding. To address this gap, this study developed a micro-level job demands-resource model and examined the mediating effect of affective risk perception on the relationship between cognitive risk perception and constructive voice behavior among 350 workers in a Korean household appliance manufacturing factory. Also, the moderating effect of safety leadership was investigated. The key findings revealed that affective risk perception fully mediated the influence of cognitive risk perception, inhibiting constructive voice behavior. Surprisingly, the negative impact of affective risk perception on constructive voice behavior is exacerbated by positive safety leadership. In conclusion, this study sheds light on the detrimental effects of perceived risk and managerial safety emphasis on employees" constructive performance, providing valuable insights for related research and practical implications in the field.
