Background. Migratory flows are due to processes of acculturation, multiculturalism and interculturalism from which hypotheses of assimilation, adaptation, selectivity and identity have been tested. Under such assumptions, it is possible to investigate phenomena of exclusion between natives and migrants that concern, in the organisational sphere, the stigma of training and quality of work. Aim. The purpose of the study was to establish the reliability and validity of an instrument that measured job stigma based on two dimensions related to training and quality of performance.
