A review of the literature about Australia's ageing workforce shows significant research into the changing demographics, and predictions of the need to employ more older workers to fill the ranks. Older workers are clearly valued by employers for their reliability, experience, and low turnover. A summary of this is provided. However, older workers still do not get hired. There is a credibility gap between what employers say they believe, and how they act. Reasons for this are posited, and suggestions made for further research.
