Job automation can undermine economic security for workers in general, and older workers, in particular. In this respect, consistently updating one's knowledge and skills is essential for being competitive in a technology-driven labor market. Older workers with lower adult literacy skills experience difficulties with continuous education and skills development, which can contribute to their economic uncertainty. Therefore, this study aimed to examine the correlation between adult literacy skills and job automation risk. We analyzed a nationally representative sample of middle-aged and older workers (age 50+ years; n = 1,880) from the 2012/2014/2017 Program for the International Assessment of Adult Competencies (PIAAC) dataset. The survey-weighted linear regression results showed that lower job automation risks (0%-100%) were a function of higher adult literacy skills (score 0-500 points: b = -0.052, p < 0.05), after adjusting for relevant covariates (R-squared = 0.19).
