You don't have to be a malicious liar to be wrong. And it's perfectly reasonable to take your employer to court if you suspect the result of the internal processes to be wrong or even covering something up. But as an employee if you take things into public media to pressure your employer via the threat of harming their public image (because that's the entire point of going public like this) -- you better have a pretty airtight case to back up your claims. An employer-employee relationship is ultimately built on trust (enshrined in a contract but still based on mutual assumptions of good faith). There's nothing strictly wrong with airing your dirty laundry in public but at that point you're terminating the relationship. The only question left at that point is whether there are any remaining obligations but thinking you can just carry on as usual is absurd. I'm not even arguing about the emotions involved. Tesla may have betrayed her trust if her allegations are true, but she definitely betrayed the company's trust by actively dragging this into the headlines.
