The U.S. has a history of marginalizing Black people. Marginalization impedes Black Americans’ ability to secure wealth, education, and meaningful work. The Psychology of Working Theory (PWT) uses a social justice lens to understand how contextual factors inform the labor market experiences of those who work and want to work. PWT highlights the ways economic constraints and marginalization predict access to decent work. We tested the PWT model with two measures of marginalization, general ethnic discrimination, and racial microaggressions, with a sample of 241 Black workers to add to the extant literature about the suitability of the PWT for racial minorities. Diverging from previous studies, we found that marginalization predicted career adaptability. Consistent with previous studies, marginalization and economic constraints predicted Black workers’ work volition and perceived access to decent work. Work volition mediated the relationship between general ethnic discrimination and economic constraints with the perception of attaining decent work.
