How should discrimination in the workplace be dealt with?

I read that a good start is to acknowledge that none of us are above developing prejudices. The book Understanding Prejudice and Discrimination says: “Perhaps the most important conclusions to emerge from prejudice research are these: (1) no one capable of human thought and speech is immune from harboring prejudice, (2) it often takes deliberate effort and awareness to reduce prejudice, and (3) with sufficient motivation, it can be done.” Education has been described as “the most powerful tool” in the fight against prejudice. The right education can, for example, expose the root causes of prejudice, enable us to examine our own attitudes more objectively, and help us deal wisely with prejudice when we are victims.
