The studies on trust have proliferated in the national and international literature. However, the relationship between organizational trust, absenteeism and turnover is rarely discussed in the literature. In order to fill this gap, this dissertation aims to analyze the impact of organizational trust on the turnover and absenteeism levels, based on two premises: (1) organizational trust impact on turnover rate; (2) the higher the organizational trust, the lower the absenteeism rate. Therefore based on a qualitative methodology was carried out a comparative case study between two bus companies, located on greater Rio de Janeiro, with the questionnaires Trust Scale Employee of the Organization (ECEO) prepared by Tamayo and Oliveira (2008) for a sample of 385 employees in the company A and 222 in company B. The responses were submitted to descriptive analysis and the pattern of responses was not exactly the same as for the model developed by Tamayo and Oliveira (2008). This study concluded that: (1) the greater the confidence in promoting employee growth and the organizational soundness, the lower will be the turnover levels; (2) the results demonstrate a negative association between rules relating to the dismissal of employees and turnover levels; (3) it is not possible to assume the influence of organizational trust in absenteeism companies.
