A top woman female Yahoo executive has been sued by a woman who worked under her for sexual harassment and wrongful termination. Maria Zhang, a senior director of engineering at Yahoo Mobile, has been sued by Nan Shi, who worked as a principal software engineer in Yahoo from February 2013.

According to a complaint filed on July 8 in Santa Clara Superior Court in San Jose, California Zhang coerced Shi to have oral and digital sex with her on multiple occasions in Sunnyvale, California, and told her she would have a "bright future" at Yahoo if she had sex with Zhang. However all went south. Shi accuses Zhang of unfairly downgrading her performance reviews for the second and third quarters of 2013.

When Shi complained about her direct supervisor's advances the company's human resources personnel refused to conduct an investigation. Instead, Shi was put on unpaid leave and eventually fired. Shi wants cash and punitive damages. The lawsuit also names Yahoo as a defendant.

Yahoo has said that there was no basis or truth to the allegations against Maria Zhang. Maria is an exemplary Yahoo executive and we intend to fight vigorously to clear her name. Zhang founded her own mobile company, Alike, which was acquired by Yahoo in 2013. She also worked at Microsoft and Zillow before joining Yahoo, according to her LinkedIn profile.
