Negative stereotyping of older workers has been identified as a major factor in employment discrimination against them. A study of Australian employers’ attitudes toward older workers found systematic negative stereotyping and low likelihood of hiring older workers. The current study employed a national random sample of 267 employers, and tested 3 interventions aimed at promoting positive attitudes toward older workers and increasing the likelihood of their hiring. The first intervention was in the form of a fact sheet; the second aimed at inducing cognitive dissonance; and the third was a combination of the two. The combination intervention produced promising results. Employers in this condition showed more favorable attitudes toward older workers overall, and greater preference toward hiring older workers.
