“Yet the flawed perceptions persist, a byproduct of stubborn and pervasive ageism. Positive attributes of older workers are crowded out by negative stereotypes that infect work settings and devalue older adults in a youth-oriented culture. Older adults regularly find themselves on the losing end of hiring decisions, promotions, and even volunteer opportunities.
Research from AARP found that approximately two-thirds of workers ages 45 to 74 said they have seen or experienced age discrimination in the workplace. Of those, a remarkable 92% said age discrimination is very, or somewhat, common. Research for the Federal Reserve Bank of San Francisco backs this up. A study involving 40,000 made-up résumés found compelling evidence that older applicants, especially women, suffer consistent age discrimination. A case in point is IBM, which is currently facing allegations of using improper practices to marginalize and terminate older workers.”
