Zaldonis says she was dismissed from her job for reporting some of the surgeons.

According to the Post-Gazette, instead of talking with the patients themselves, the lawsuit suit says doctors had resident physicians, nurse practitioners, and physician assistants obtain the patient consent.

Inside the lawsuit, it says that doing so is “in violation of federal and state law as well as UPMC policy.”

The suit is requesting damages to the federal agencies as well as getting Zaldonis her job back with back pay.
