Managers Can Support Employees in Working-Class Contexts by Promoting Growth Mindsets

White-collar workplaces are critical "gateway" contexts. They play a crucial role in providing valuable opportunities and upward social mobility. Some groups are less likely, however, to feel they belong in these settings. For example, those with a college degree may feel relatively at ease. However, those without may be uncertain about whether they will be fully included. We examine one possibility for addressing these class-based belonging gaps. A growing education literature demonstrates the power of growth mindsets. We extend this research to the workplace and test its benefits. In two preregistered experiments (N = 1,777), we find that endorsing growth mindsets can support working-class (WK) individuals. When managers have a growth mindset, WK individuals report high sense of belonging. The effect occurred because managers with growth mindsets reduced identity threat. A preregistered survey of employees in the real world (N = 300) triangulated these findings. Sense of belonging was higher among those who believed their manager had a growth mindset. Furthermore, they reported greater job satisfaction and commitment. These findings have important implications for the growing conversation on addressing class divides.
