Experiencing prejudice
Think carefully about whether you want to speak up, weighing the costs and benefits of doing so. Don’t assume the person knows she is being offensive; it’s possible that she is just clueless. It’s generally best to ignore offence, and to disassociate yourself from her as much as possible. If you chose to react, speak to the person directly first. Let her know your preference not to be spoken to or about that way. Ask her calmly and politely: “can you do me a favor and not speak that way to me/around me? I’m uncomfortable with that language/ expression.” Take care of your emotions, don’t let her win by becoming furious. In case she continues to be offensive, than she is a bully and you have the right to recourse through a common superior.
