As political polarization rises globally, the question of how to bridge political differences and exchange perspectives becomes increasingly important. One way to learn about and understand different political perspectives is through political discussions with colleagues, who may not share the same political opinions. In this study, we examined the relationship between political discussions at work and tolerance, as well as the moderating effects of political heterogeneity of the work team and perceived psychological safety on this relationship. We collected data from 242 German employees and found that political discussions at work were significantly and positively associated with tolerance. Additionally, perceived psychological safety moderated this association, increasing the positive relationship between political discussions and tolerance. Political heterogeneity of the team was associated with more political discussions, but lower perceived psychological safety and was not significantly related to tolerance. These findings imply that having political discussions at work can improve understanding of different political perspectives and increase tolerance for diverse viewpoints. Perceived psychological safety is an important contextual factor that allows employees to discuss political topics at work, thereby strengthening the positive association with tolerance. Therefore, we recommend ensuring that employees perceive their team as safe, as this helps the team function and could positively impact society. However, we encourage future research to examine the causality of the observed associations.
