The court push from the EEOC could also signal that the agency—known in the last decade for promoting systemic change—may continue on that path even under the Trump administration, which suggested through agency appointments an ideological shift toward business-friendly policies.

The EEOC’s action in the Ninth Circuit is evidence that the agency is continuing to push a pro-enforcement position in the absence of any direction to shift priorities, said David Lopez, former general counsel to EEOC in the Obama administration who’s now a partner at Outten & Golden in Washington.

Anti-discrimination laws tend to be a nonpartisan issue, Lopez said, but time will tell whether the Trump administration’s appointments and senior hires will affect the agency. “That decision was surprising and shocking to folks who have been really pressing the eradication of the pay gap,” Lopez said. “It’s been such a persistent issue.”

In 2012, Aileen Rizo, who worked for a Fresno County, California, public school, brought a lawsuit against her employer after she discovered her male co-workers were making higher salaries despite comparable or equal experience.

The county’s standard policy for hiring added 5 percent to previous pay and then bumped her up to the minimum for her position at $63,000. Male colleagues with similar experience made as much as $10,000 or more than she earned, according to her complaint.

The Equal Pay Act creates exceptions when pay is based on seniority, merit, quantity or quality of work or “any other factor other than sex.”

The EEOC said in its filing to the appeals court that Fresno County’s practice undermines the purpose of the Equal Pay Act because it “institutionalizes” the gender pay gap. The commission said prior salary alone cannot be considered an exception.

“The county argued that it does not discriminate on the basis of sex; its practice is gender neutral,” EEOC attorney Barbara Sloan wrote in the commission’s brief. “But to the extent that one employer discriminated in pay against a female employee, the next employer—even one like the county whose practice is simply to carry forward any existing pay discrepancies—would benefit from the prior discrimination to the detriment of that employee by paying her less than male employees not similarly subject to prior discrimination.”

Two federal appeals courts—the Tenth and Eleventh circuits—previously held that prior pay alone cannot be considered as an exemption to equal pay laws. “They reason that ‘if prior salary alone were a justification, the exception would swallow up the rule and inequality in pay among genders would be perpetuated,’” Sloan wrote. The Seventh Circuit has ruled that previous salary could be considered.

Thomas of the University of Akron said paying women lower salaries is systemic in the employment market. When women first began working as teachers in the early 19th century, salaries dropped 75 percent once women began replacing men. That trend continued in the Industrial Age when employers paid a new wave of women workers less because it was assumed their jobs were their secondary responsibility to raising a family.

She also noted a slew of state and local laws passed in recent years and months that move in the opposite direction of the Ninth Circuit’s decision. States, for instance, are passing laws that prohibit employers from asking a job candidate for his or her previous salary during job negotiations.
