This study compared people aged 50 to 65 who had retired and returned to work (n = 90), who remained in their career jobs (n = 198), and who retired and remained out of the workforce (n = 321). The significant differences between post‐retirement and career employment were associated with the HR practices within organisations and were not related to the characteristics of the organisations in which post‐retirement and career jobs were found. The HR practices were rated as especially important in influencing the decision of retirees to return to work. The findings suggest that people in post‐retirement jobs are drawn to organisations that provide HR practices tailored to the needs and desires of older workers. The results also indicate that if employers expect to address labour shortages by encouraging retirees back into the workforce, they are going to have to implement those HR practices that are important to this group.
