It’s become a popular explanation for the gender-wage gap: Women are less likely than men to self-advocate for a pay raise. It has an appealing logic. If we can get women to negotiate more like men, then the gap will shrink. This is in part why there has been a surge in negotiation trainings for women. For example, in 2015, Boston Mayor Marty Walsh launched a five-year partnership with the American Association of University Women (AAUW) to offer free salary negotiation workshops to women in the city of Boston. These trainings are now offered across the nation.
