Drawing on the relational and uncertainty models of justice, this research investigates the consequences of daily overall team justice perceptions on employees' daily psychological strain. Specifically, we examine daily psychological safety as a mediator of the relationship between daily overall team justice evaluations and daily psychological strain. We also argue that daily overall supervisor justice moderates this mediated relationship. Using a daily diary study over 10 consecutive working days, our results confirm that daily team justice reduces employees' daily psychological strain. In addition, our findings provide evidence that daily psychological safety mediates the effects of daily justice perceptions on daily psychological strain. Results also show that the relationship between daily overall team justice and daily psychological safety is moderated by overall supervisor justice, thereby complementing the target similarity model.
