The extant literature lacks evidence concerning the effects of qualitative and quantitative job insecurity (JIS) on service workers’ performance outcomes. This is also true for their effects on green work outcomes. To fill in this void, drawing on social information processing, threat-rigidity, and the reformulation of attitude theories as well as the model of attitude–behavior relation, this paper proposes and tests a research model that investigates the effects of both qualitative and quantitative JIS simultaneously on green work outcomes. Data gathered from hotel employees during the COVID-19 pandemic in Turkey were utilized to gauge the hypothesized associations through structural equation modeling. The findings suggest that quantitative JIS weakens harmonious environmental passion, green recovery performance, and proactive pro-environmental behavior. In addition, harmonious environmental passion mediates the impact of quantitative JIS on the aforementioned green work consequences. Contrary to the predictions, the findings lend no credence to the negative impact of qualitative JIS on harmonious environmental passion, green recovery performance, and proactive pro-environmental behavior.
