Black employees at Apple, Bank of America, Capital One, and Starbucks give high marks to the workplace culture at the companies, according to a report from Glassdoor that offers a sense of how minority workers are faring at some of America's best-known corporations.

The analysis of company ratings and ethnicity appears at a time when major companies, including Microsoft, Wells Fargo, and Salesforce, have publicly vowed to increase diversity hiring and make their workplaces more welcoming to workers of color. Glassdoor researchers said their report, released Thursday, highlights companies that are making good on their commitment to diversity and inclusion. 

Of the 28 companies analyzed in the report, Apple scored the highest rating, 4.2 out 5.0, from employees who self-identify as Black or African American. About 9% of the California tech giant's workforce is Black, according to company data from 2018. Bank of America got the second-highest score at 4.0, followed by Starbucks and Capital One (both 3.9).
