(1) Background: The purpose of this study is to examine the relationship between social support in the workplace for childcare teachers, resilience, and self-care. This study explores the inner mechanism that helps to strengthen self-care of childcare teachers, which enables teachers to provide quality care to children and promote their own wellbeing. (2) Methods: The survey was conducted from September to October 2018 for childcare teachers in Seoul and Gyeonggi Province using convenience sampling. Out of 550 questionnaires, 491 were returned, with 466 used for the analysis, excluding those with incomplete responses. The collected data were analyzed using descriptive statistics, correlation analysis, and mediation analysis. (3) Results: There were significant correlations between all variables. The mediation analysis showed a complete mediation of resilience. (4) Conclusion: Childcare teachers first have to take good care of themselves in order to perform well as a childcare professional. Educational materials and counseling programs tailored for childcare teachers need to be developed for better self-care and building greater resilience. Materials for directors of daycare centers, as well as teachers stressing the importance of social support for each other, will help childcare teachers' effective functioning in their professional and personal life. Prevention and intervention programs for self-care will eventually help lower the costs of healthcare in society.
