Facebook Chief Operating Officer Sheryl Sandberg may take the stand in an antitrust lawsuit stemming from her days as Google’s vice president of global sales and operations. Google, Intuit, Apple, Intel, Adobe, Pixar, and Lucasfilm are the subject of a civil suit. The companies are criticized for allegedly keeping wages lower by agreeing not to poach employees from each other.

Facebook is not involved in the lawsuit, but CNET reports that Sandberg may be asked to take the stand, as her employment agreement with Google is one of six documents the company offered to the court.

According to CNET, Judge Lucy H. Koh (who presided over Facebook’s sponsored stories lawsuit) is still determining whether or not the case should proceed as a class-action lawsuit, which would open damages up to more employees.
