One of your co-workers brought along his friend to lunch. When discussing his new female boss, the friend says: "It really irritates me not only that she gets the job just because she's a woman, but she's also Hispanic. There's no way that someone like me had a chance given her pedigree. And she now has the gall to act as if we're all one big happy team and the rest of us should accept her leadership. As for me, I'll do best to make it difficult for her to succeed.
It was uncomfortable for you just to hear this. Your co-worker looks dismayed but isn't saying anything. What do you do? How have you reacted in situations like this in the past?
