The U.S. Soccer Federation has yet to respond to Friday’s filing of a lawsuit by the United States women’s national team for “institutionalized gender discrimination.”

Attorneys for the team cited the Equal Pay Act and Title VII of the Civil Rights Act when they filed in U.S. District Court in Los Angeles, on International Women’s Day.

A spokesperson declined to comment.

The suit names all 28 members of the team as plaintiffs and because they seek class-action status, any one who played since February 2015 to join the civil action. This comes just three months before the team’s title defense at the 2019 FIFA Women’s World Cup in France.

The players say the discrimination impacted their wages and the way they train and compete. They’re demanding to be paid the same as the men’s national team, equal treatment, and damages, including back pay.

”The USSF discriminates against Plaintiffs, and the class that they seek to represent, by paying them less than members of the MNT [men’s national team] for substantially equal work and by denying them at least equal playing, training, and travel conditions; equal promotion of their games; equal support and development for their games; and other terms and conditions of employment equal to the MNT,” the players said, according to court documents.

The women claim U.S. Soccer provided the men’s team with performance bonuses totaling $5.375 million for losing in the round of 16 at the 2014 World Cup, while the federation provided the women with $1.725 million for winning the 2015 World Cup.

”From March 19, 2013, through December 31, 2016, WNT players earned only $15,000 total for being asked to try out for the World Cup team and for making the team roster,” the lawsuit says. “MNT players, on the other hand, earned $55,000 each for making their team’s roster in 2014 and could have earned $68,750 each for making their team’s roster in 2018.”

Five of the players filed a wage-discrimination complaint in 2016 with the federal Equal Employment Opportunity Commission, which dragged its feet but ultimately gave them the green light to sue.

In 2017, U.S. Soccer and women’s team players ratified a new collective bargaining agreement which runs through 2021. The federation rejected their requests for compensation equal to the men’s team, say the women, during collective bargaining for that new contract.

”Despite gains achieved by the 2017 collective bargaining agreement between the USWNT players association and the USSF, the USSF’s ongoing policies and practices of systemic gender discrimination also extend beyond pay and into nearly every aspect of players’ work conditions,” the women players said in a statement.

”This includes playing, training, and travel conditions; promotion of games; staffing including coaching, medical personnel and training, and operations; support and development for games and other terms and conditions of employment that are less favorable for female players than their male counterparts.

”The lawsuit filed today seeks an end to the USSF’s discriminatory practices, and financial damages in order to address the pay gap for USWNT players, as well as liquidated and punitive damages and all other appropriate relief.”

The U.S. National Soccer Team Players Association released a statement in support of the USWNT.

”The United States National Soccer Team Players Association fully supports the efforts of the U.S. Women’s National Team Players to achieve equal pay,” the statement said. “Specifically, we are committed to the concept of a revenue-sharing model to address the U.S. Soccer Federation’s ‘market realities’ and find a way towards fair compensation.

”An equal division of revenue attributable to the MNT and WNT programs is our primary pursuit as we engage with the US Soccer Federation in collective bargaining. Our collective bargaining agreement expired at the end of 2018 and we have already raised an equal division of attributable revenue. We wait on US Soccer to respond to both players associations with a way to move forward with fair and equal compensation for all US Soccer players.”
