This study focuses on how the imbalance between efforts and rewards relates to active participation in the social and labor markets of senior citizens who retire from the front line of corporate organizations, and it aims to clarify how others’ words are related to their intention to continue in social activities. We asked 104 senior and pre-senior individuals who participated in social activities to describe the words they were happy with and asked about effort-reward imbalance and their intention to leave. Text mining and analysis using KH Coder revealed that there was a difference in characteristic words between when receiving rewards and when no rewards were received. When receiving rewards, words that evaluated work and behavior were seen as characteristic words. On the other hand, when there was no reward, words that focused on the existence of individuals were also seen as characteristic words. This suggests the importance of paying attention to and recognizing the senior generation’s attitudes and actions rather than merely providing monetary rewards.
