MGM Resorts International Operations Inc. paid a female executive director of strategic operations as much as 20 percent less than younger male colleagues who performed similar work at a similar level, a federal lawsuit alleges.

The complaint comes as recent reports by organizations such as the Institute for Women’s Policy Research have found the gender wage gap is stagnating or slightly worsening based on some measures. The gaming industry in particular faces greater scrutiny of gender disparities following the February resignation of casino executive Steve Wynn after harassment allegations.

Karla Tucker worked as an executive director of strategic programs for MGM in Las Vegas from 1996 to 2017, she says in a complaint filed March 12 in the U.S. District Court for the District of Nevada. Tucker says she was singled out at age 59 as the oldest woman in her department. MGM paid several male co-workers about 20 percent above her base salary of $150,000 for equal work in similar executive-level positions, the complaint said.

Tucker, who still works for the company, says she was given the option of leaving or taking a demotion as part of a June 2017 department reorganization. Younger male co-workers weren’t similarly affected, the complaint said.

Tucker alleges violations of Title VII of the Civil Rights Act of 1964, the Equal Pay Act, the Age Discrimination in Employment Act, as well as Nevada law. She seeks lost wages and benefits as well as damages for “emotional pain, suffering, inconvenience, mental anguish and loss of enjoyment of life.”

MGM declined to comment to Bloomberg Law.

Tucker and her lawyer are “looking forward to finding a resolution to the egregious way Ms. Tucker was treated,” her attorney, Jenny Foley with HKM Employment Attorneys LLP, told Bloomberg Law in an email.

The case is Tucker v. MGM, D. Nev., No. 2:18-cv-00443, complaint filed 3/12/18.
