AbstractObjectiveTo assess the magnitude of racial–ethnic disparities in pandemic‐related social stressors and examine frontline work's moderating relationship on these stressors.Data SourcesEmployed Californians' responses to the Institute for Governmental Studies (IGS) poll from April 16–20, 2020, were analyzed. The Pandemic Stressor Scale (PSS) assessed the extent to which respondents experienced or anticipated problems resulting from the inability to pay for basic necessities, job instability, lacking paid sick leave, unavailability of childcare, and reduced wages or work hours due to COVID‐19.Study DesignMixed‐effects generalized linear models estimated (1) racial–ethnic disparities in pandemic stressors among workers during the first COVID‐19 surge, adjusting for covariates, and (2) tested the interaction between race–ethnicity and frontline worker status, which includes a subset of essential workers who must perform their job on‐site, to assess differential associations of frontline work by race–ethnicity.Data CollectionThe IGS poll data from employed workers (n= 4795) were linked to the 2018 Centers for Disease Control and Prevention Social Vulnerability Index at the zip code level (N= 1068).Principal FindingsThe average PSS score was 37.34 (SD = 30.49). Whites had the lowest PSS score (29.88, SD = 26.52), and Latinxs had the highest (50.74, SD = 32.61). In adjusted analyses, Black frontline workers reported more pandemic‐related stressors than White frontline workers (PSS = 47.73 vs. 36.96,p< 0.001). Latinxs reported more pandemic stressors irrespective of frontline worker status. However, the 5.09‐point difference between Latinx frontline and non‐frontline workers was not statistically different from the 4.6‐point disparity between White frontline and non‐frontline workers.ConclusionLatinx workers and Black frontline workers disproportionately reported pandemic‐related stressors. To reduce stress on frontline workers during crises, worker protections like paid sick leave, universal access to childcare, and improved job security are needed, particularly for those disproportionately affected by structural inequities, such as racially minoritized populations.
