I’m not sure I believe this former employee either. I read the “reasons they left,” and it’s simply too unbelievable
Statements from actual victims often do. That's part of the problem with the culture of not believing, or even alienating, victims. I'm not saying it should be treated as evidence against the company, but the company absolutely should make sure this believe is not happening internally and those of us on the outside should be charitable towards this former employee's testimony unless contradictory evidence shows up.
Using the Depp/Heard thing as a point of reference. There were good reasons to suspect her claims were fabricated or exaggerated, but I've also known people who have gone through many of the relationship experiences she testified about. Until she had her day in court and showed the world her (probable) dishonesty, even she deserved the benefit of charity. Or else by sheer misfortune we will start telling real victims they made it up.
