For new mothers, feeling like you belong can be the difference between surviving or thriving in the transition back to work. In this paper, I explore belonging as a psychological construct, including how it is measured, experienced and cultivated in different contexts, and apply that to the realities of working motherhood. Mothers who successfully find belonging experience higher well-being as individuals. Organizations who are able to help new mothers find belonging positively impact the diversity of their workforces and can rectify the inequality in women’s work experiences. A sense of belonging can foster many elements of well-being. This paper not only reviews the literature on belonging, but also provides a roadmap for working mothers and those who support them at work.
