Design/Methodology/Approach: Empirical research conducted on Italian organizations affected by the crisis shows that the model is significantly distorted under such conditions. To verify the internal structure of the Job Performance Model based on EDC under given critical conditions, the statistical analysis of correlation, linear regression analysis and the path analysis were executed using SPSS and SPSS AMOS. Findings: The research result of statistical analysis confirm that the new version of the Model obtained for organizations operating under Black Swan phenomenon is statistically significant without work motivation and job satisfaction. It was also proven that P-J fit still provides a bridge between EDC and job performance, trough strengthening work engagement.

They propose mechanisms that will potentially help the organization to survive the crisis through appropriate shaping of job performance, which indirectly determines the continuity of the organization.
