Considering the degree and rate of aging of construction workers around the globe, which is compounded by intensifying labor shortages, the industry requires serious attention to workplace policies that safeguard older workers against ageist stereotypes and prevent early retirement while at the same time attracting younger workers. Ageism has been identified as a barrier in all four layers of career progression (recruitment and hiring, retention, promotion, and firing/dismissal). Therefore, the steps to tackle ageism in the construction industry need to include a strategy that ensures the career progression of older and experienced workers, and an approach that welcomes a more diverse young workforce. Through a comprehensive literature review, this research sought to explore the current state of ageism in the construction industry. The findings of this research show that even though minimal research has been conducted thus far, there is a strong business case that justifies further research in this area. Research findings further point out to ageism as a threat in career progression. Sources of ageism barriers include societal and employer attitudes, coded language, and worker self- directed ageism. This research recommends both quantitative and qualitative analyzes of the prevalence and impacts of ageism in the construction industry.
