Objective: To determine the psychometric properties of the original four-item Occupational Insecurity Scale in Peruvian workers. Material and Methods: Transversal and instrumental study that took the Work Insecurity Scale to be able to validate it in the context of the COVID-19. With a sample of 332 workers from public and private entities, the form and content of the scale was validated. Results: Aiken’s V was found with values > 0.70 for the four items. The values of asymmetry and kurtosis were 24.3. In addition, AFE is justified with a KMO (0.780) and a Bartlett (654,235; gl = 6; p < 0.001). As a result, all items were condensed into a single factor. Finally, the values (λ) for the one-dimensional model were significant (item 1 = 0.85; item 2 = 0.90; item 3 = 0.84; item 4 =-0.40). Conclusions: The Perceived Insecurity at Work Scale (LABOR-PE-COVID-19) is a valid, clear and representative scale.
