Reflection on events at work, including errors is often as a means to learn effectively through work. In a cross-sectional field study in the banking sector, we investigated attitudes towards workplace errors (i.e. error orientation) as predictors of reflective activity. We assumed the organisational climate for psychological safety to have a mediating effect. The study participants were 84 client advisors from the retail banking departments in branches of a German bank. The client advisors' were being affected by a range of changes in their workplaces at the time of the data collection. This situation afforded these workers opportunity for learning but also involved the risk of error by these staff. Regression analyses identified that error competence and learning from errors were significant predictors of reflection. The results confirmed the mediating role of psychological safety on the association between attitudes towards errors and reflective working behaviour.
