The question is "Did Google verifiably lie?"
I'm not trying to prove she "voluntarily quit" vs was "discharged" via California law. I'm arguing that Google used resigned in a way that wasn't a lie, and referencing California law to show how it uses the word resignation, and is therefore a reasonable use of the word.
Did Google use the word resigned in a reasonable way?
1. Gebru submitted a conditional resignation, and demonstrated she wanted to leave the job
2. California law says that conditional resignations count as resignations, as well as accelerating resignations(depending on pay)
3. Gebru did not withdraw her resignation
4. Gebru no longer wished to work at Google
5. Gebru(as a manager) advised co-workers to stop work
6. Google "accepted" her resignation.
I don't think Gebru is a liar either. I think that her resigning and being fired are both reasonable one word descriptions of the events. Fired implies she wanted to continue working at Google, and resigned implies Google wanted to keep her employed. But neither of those were true.
They just mutually decided they weren't a good fit. Gebru because she thinks Google is evil, and Google because they thought Gebru was being unprofessional.
