Background The aging of the workforce, coupled with the changing nature of career
tenure has raised questions about the impact of these trends on work disability. This study
aimed to determine if age and tenure interact in relating to work disability duration.
Methods Relationships were investigated using random effects models with 239,359
work disability claims occurring between 2008 and 2012.
Results A 17-day difference in the predicted length of disability was observed from ages
25 to 65. Tenure moderated the relationship between age and length of disability. At
younger ages, the length of disability decreased as tenure increased, but at older age, the
length of disability increased as tenure increased.
Discussion Results indicate that although there is a relationship between length of
disability and tenure, age makes a greater unique contribution to explaining variance in
length of disability. Future research is needed to better understand why specifically age
shows a strong relationship with length of disability and why that relationship varies with
age
