NEW YORK (AP) — When Serena Williams told the umpire at the U.S. Open final that he owed her an apology, that he had stolen something from her, and then she got penalized for her words, Breea Willingham could relate to her frustration and anger. Willingham isn’t a tennis star, but she is a black woman. She and others like her say Williams’ experience resonates with them because they are often forced to watch their tone and words in the workplace in ways that men and other women are not.
