White workers in U.S. retail and food-service industries are more likely to get regular shift work than other employees, according to a recent study. "What we find is that, pretty much across the board, white people have better schedules than workers of color," said Adam Storer, a Ph.D. candidate at the University of California, Berkeley, and an author of the study. Three-quarters of all respondents in a survey of more than 30,000 Americans said they had experienced one of the scheduling issues, according to Storer. But there were statistically significant gaps between white and nonwhite workers across all measures, and so-called precarious scheduling was worse for women than men.
