Ableism is a form of discrimination based on a person's physical or mental abilities. It can manifest itself in the workplace through hiring, assignment and promotion practices that give preference to individuals with certain abilities. This type of discrimination can be seen in cases where employers assume that a person with a disability cannot perform at a high level, without taking into account their qualifications and experience. In addition, ableism often takes the form of exclusionary language such as "unable to work" or "disabled", which reinforces negative stereotypes about people with disabilities, and limits their access to career opportunities. 

Human resource professionals must combat ableism if they are to create a fair work environment where everyone has an equal opportunity to succeed, regardless of any limitations related to physical or mental differences.
