Analysis of factors associated with employee dismissal in nonpublic companies in the Northeast

Abstract

This study compares Survival Analysis models to assess risk factors for employee dismissal in non-public companies in Brazil’s Northeast. Data were sourced from the 2015 Annual Socioeconomic Information List across all Northeast states. Findings show that most workers working in in these companies are Brazilian men, mixed race, Brazilians and aged between 18 and 39 years old. Workers in capitals and metropolitan regions have a salary range of up to three minimum periods and work from 41 to 44 hours per week. They are hired through reemployment, remain at the companies for approximately three months and are terminated due to unfair termination at the employer’s initiative. By comparing survival models with the Kaplan-Meier estimator and using the Akaike Information Criterion, the generalized gamma model emerged as the best fit. In the final model, key covariates included worker sex, age, race/color, and average salary range defined by minimum wage intervals.
