Previous research has investigated the impact of organizational justice, defined as the treatment workers receive from an external authority (supervisor or the organization as a whole), on performance as achievement of task objectives. However, there is a lack of diary studies that consider other sources of justice beyond an external authority. This study analyzes the link from two sources of justice, justice from the supervisor and peer justice, to workers' performance. To do so, we carried out a diary study to examine variability in employees' performance as a consequence of variability of daily justice treatment perceived by workers. We conducted a field survey investigation using a sample of 28 workers of a company that pertained to the automotive sector, during 10 successive days. Our findings showed significant average correlations between performance, on the one hand, and both justice from supervisor (r = 0.41, t(26) = 2.29, p < .05) and peer justice (r = 0.44, t(26) = 2.49, p < .05). In addition, it was confirmed a significant and positive relationship between justice from the supervisor, perceived the first measurement day, and employees' performance measured 10 days after. By contrast, this relationship was not confirmed for peer justice. We conclude the following: a) changes in justice are associated with changes in performance; and b) justice from the supervisor, measured at the starting point, is able to predict performance ten days after.
