Having been a manager, about 1/10th of employees had... issues. Those employees took up an inordinate amount of management time and especially energy.
I don't know whether she or her manager were the problem; in most cases, it's 50/50. If I know a potential hire had issues before, it raises the risk of a hire a lot. I want to avoid that kind of employee.
If they act unprofessionally after leaving, that goes up to 95/5. Perhaps her boss had issues, but she definitely did as well. Posting a list of management emails? Naming her boss publicly? That goes to a serious red flag.
When I was managing, I would never have hired someone who did this. The risk goes in several directions too. Since then, I've picked up a harassing stalker. Having an employee do this sort of thing went from psychologically draining to potentially devastating to my safety.
Privacy is kind of important.
Being young, in your "dream job" and then being told "there’s someone waiting outside to collect your corp devices" without any real explanation. It's 100% HR + Managers fault that this situation has escalated to this.
If a future employer asks for a reference from Google she's screwed.
This whole "don't say anything bad about X, it will reflect badly on you" is how the Epsteins and Weinsteins of the world go undetected for years.
If what she says is true she should probably go to a lawyer and sue.
But the complaints here seem to be related to performance management. Getting a frustratingly low rating. Being told that they aren't doing enough work. For this sort of situation I'd expect the firing process to take months.
"CME for missing a meeting" is strange, but the good news is that manager calibration notes are stored in durable systems and in many locales people have the legal right to see them. So it'd be possible to see if this was actually the reason for a rating.
We'll see if more information comes out.
If a manager really wants you gone they can manufacture evidence and have you yanked quickly by constructing unobtainable and/or subjective PIP targets.
It'd also be extremely odd to be on a PIP after receiving a Consistently Meets Expectations rating. Only a subset of Needs Improvement ratings actually get PIPs. CME, by definition, means that you are doing your job sufficiently.
If a future employer checks and see she was asking people to go and harass her former managers and HR, it'd reflect pretty badly on her; I know I wouldn't want her in my team.
And as for what she can do, isn't wrongful termination illegal? Like she could instead open a civil case against Google
Name-and-shame is... random. I've never been hit, but the people I've seen hit... It hasn't had much to do with them, so much as with the people doing the shaming.
