Ageism is conscious and unconscious prejudice, stereotyping, and discrimination against people solely based on their age. Although the term is not new—it was coined in 1969 by Robert Neil Butler—its effects are being felt in the workplace more strongly today than ever. As people live longer and stay in the workforce longer, the issue of ageism is having a detrimental effect on older workers and posing a challenge for hiring, retention, and engagement practices.
