Statistics of Discrimination in workplaces

This chart of discrimination at workplaces from the website https://www.pewresearch.org/fact-tank/2018/01/10/black-stem-employees-perceive-a-range-of-race-related-slights-and-inequities-at-work/ show how blacks feel the most discriminated against when getting a job, a promotion, and at work. Out of the whites, hispanics, asians, and blacks, whites feel the most comfortable in their environment. This comes to show that racism does exist and it is affecting people at their work. How are they supposed to feel safe when they are judged by the co- workers?
