Republican senators again filibustered the Paycheck Fairness Act yesterday, an act that would provide women with additional tools to identify and fight back against pay discrimination. This is the fourth time that Republicans have blocked this bill, despite the persistence of unequal pay for women and men doing the same work.

It’s been over 50 years since the signing of the Equal Pay Act, yet, this unconscionable practice of paying women employees less than men for doing the same job continues to this day.

In Congress, though, Republicans derided the measure as a “show vote” staged by Democrats in an election year. Sen. Mitch McConnell even claimed this bill “threatens to hurt the very people that it claims to help.” But for women working full-time and earning an average of 77 cents for every dollar men earn, this bill would give them the tools to fight back against the pay discrimination that keeps them earning less.

Women are increasingly serving as the primary breadwinners for their households, which means the discrepancy in pay harms not only women’s lives, but also their families. The Paycheck Fairness Act is the best way to start fixing that injustice. Republican senators should stop the unnecessary filibusters so that the Senate can pass this bill and move our country towards equal pay for equal work.
