The research was descriptive and quantitative, and it was conducted in a soft drink Industry, in Brazil. Hypotheses (n=9) were raised and was applied a questionnaire for 310 employees, considering the constructs: Internal Communication, Trust in the Co-workers, Trust in the Manager, Organizational Identity and Performance. The results showed that the hypotheses H1, H3 and H7 were confirmed. The higher the organizational identification, the greater will be the trust in the manager and the performance. In H4, the study confirmed that there is a lower influence of the Internal Communication on Performance. Thus, the Internal Communication does not support the Performance.
