The term "old-girl networks" refers to the close connections and support systems that exist among women who have been in the same industry for an extended period. Synonyms for this term include "sisterhood," "women's network," and "women's club." These terms are often used when discussing the advantages and benefits that women receive from networking and the support of other women. Other similar terms include "mentorship," "sponsorship," and "advocacy," all of which refer to the relationships that women build with one another to advance their careers and reach their full potential. These networks are essential for women in many fields, particularly those that are male-dominated or have a history of gender bias and wage inequality.
