Tenet Healthcare Corp.'s CEO and others must be deposed in a lawsuit alleging that the company fired two employees in retaliation for making complaints about alleged unsanitary hospital conditions, a federal district court said. This decision is another in a string of recent rulings rejecting the so-called Apex Doctrine, a principle that top corporate officers are generally too busy and important to be forced to give testimony. Denise Bonds and Shenia Rhodes, who worked as housekeepers at a Detroit hospital, allege that the defendants engaged in cost-cutting measures that made the hospital unsafe during the COVID-19 pandemic.
