"To be a black professional is often to be alone. Most black doctors, lawyers, journalists, and so on—those in white-collar positions that require specialized training and credentialing—work in environments where they are in the racial minority...In a study of black professional workers in a number of different occupations, I found that these employees worked to carefully manage their emotions in ways that reflected the racial landscapes they inhabited...Put simply, they can be visibly black, but don’t want to be perceived as stereotypically black....The same is true for professional workers who are members of other racial minority groups. For instance, Latina attorneys may be able to advance further at work if they take pains not to speak with any trace of an accent." http://www.theatlantic.com/business/archive/2015/10/being-black-work/409990/
