Job insecurity is a toxic stressor brought forward by the world’s financial crisis. The purpose of this study is to demonstrate that comparative judgements predict a unique percentage of job insecurity’s variance, above self esteem. Subsequently, questionnaires were applied via social media or via paper-pencil to 108 participants. Hierarchical regression results show that comparative judgements do not have any incremental effect in predicting job insecurity above self esteem. Self esteem predicts 21% variance in job insecurity. In conclusion, job insecurity is predicted by how individuals globally evaluate themselves, with comparative judgements regarding one’s own performance or the company’s performance having no incremental predictive power. These two variables can be regarded as undifferentiated from self esteem.
