Which term refers to attitudes that may lead to unfair treatment?

The term that refers to attitudes leading to unfair treatment is bias or prejudice. This encompasses preconceived opinions or attitudes that can shape an individual's behavior and decision-making, often resulting in discrimination against certain groups or individuals. Bias can manifest in various forms, including racial, gender, or socioeconomic prejudices, which unfairly influence judgments about people based on their membership in these groups.

In contrast, stereotyping involves oversimplified and generalized beliefs about a group that may or may not lead to unfair treatment but does not inherently imply a negative attitude toward individuals. Professionalism signifies adherence to ethical standards and behaviors expected in the workplace and does not relate directly to unfair treatment. Finally, assumptions are beliefs or statements taken for granted, which may not involve any direct intent toward unfair treatment but can still lead to misunderstandings or misinterpretations of individuals. Therefore, bias or prejudice is the most appropriate term as it directly highlights the attitudes that can cause unfair treatment.
