A study has shown that weakening unions increases gender inequality:

Barbara Biasi, assistant professor of economics at the Yale School of Management, recently published a study that concluded that eliminating unions increases the gender gap in wages.

She looked at data from Wisconsin, before and after Scott Walker eliminated collective bargaining rights in 2011, in his Koch-funded effort to destroy unions.

Barbara Biasi, an assistant professor of economics at Yale SOM, had an opportunity to examine this question when Wisconsin passed Act 10, legislation that essentially weakened the power of teachers’ unions. Afterward, schools had much more latitude in deciding how much to pay teachers.

Five years after union agreements expired, male teachers earned about 1% more per year than female colleagues with similar experience and skills, reported Biasi and her co-author, Heather Sarsons at the University of Chicago Booth School of Business. The gender gap was even higher among younger teachers.

The anti-union wing of the Democratic Party (the identity politic folks) has always dismissed unions as bastions of racism and sexism, and the history clearly shows that, but dismissing unions hurts the people that they claim to want to help.

Pass the damn Pro Act, and strengthen the rights of workers to organize.
