Government investigators looking into how Google pays its employees have accused the tech giant of shortchanging women doing similar work to men.

A U.S. Department of Labor official disclosed the agency's allegations during a Friday court hearing in San Francisco.

"We found systemic compensation disparities against women pretty much across the entire workforce," Janette Wipper, a Labor Department regional director, testified, according to a report published by The Guardian.

Google said it vehemently disagreed with the charges, which the Mountain View, California, company said it hadn't heard until Wipper's court appearance.

"Every year, we do a comprehensive and robust analysis of pay across genders and we have found no gender pay gap," Google said in its statement.
