My study helps address the lack of scientific research on the role of emotional intelligence in afterschool supervisors’ ability to manage stress at work. In this quantitative correlational study, I investigated the relationship between the emotional intelligence of afterschool supervisors serving low-income communities in New York City and their perceived workplace stress. I found a negative correlation—that is, supervisors with higher emotional intelligence tended to have lower workplace stress. The results can help afterschool supervisors and organization leaders understand the importance of emotional intelligence for effective program management. Equipped with that understanding, they can identify resources supervisors need to manage their workplace stress, facilitate 21st century learning, and mitigate the effects on youth of adverse environments.
