Olson, who was testifying on behalf of the U.S. Chamber of Commerce, said that the bill provides the same protections to men as it does to women.
"An employer would have to show that the woman was being paid more because of a factor other than sex, such as a qualification, advanced degree, or more experience," she said.
Alexander, who opposed the bill, said that it would result in "more lawsuits," not higher wages for women, according to the Huffington Post.
He also suggested that Democrats are only pushing the equal pay bill to "recapture some political crown because of the disaster Obamacare's been."
The Paycheck Fairness Act would require employers to provide the reasoning behind wage differences between employees who hold the same position, such as education or experience. It would also require the Department of Labor to work with employers to close the wage gap between men and women. The Senate should vote on the bill next week.
