Methodology:

Quantitative study, experimental design with pretest-posttest and control group, and explanatory scope. Data were collected through a pre- and post-test. The sample was random and included 60 workers of this entity, who were distributed in two groups of 30 elements each and were administered a 20-question questionnaire.

According to the Mann-Whitney U statistic, it was found that in the pretest the perception of organizational culture obtained a value of 0.216 higher than the theoretical Sig.
