> Isn't the definition of "ultimatum" that no further compromise is possible?
Given that, at least in Timnit's narrative, the email included a request to discuss the issue in person when she returned from vacation, I don't think that the "ultimatum" characterization is uncontroversially accurate for the immediate case.
I'm responding narrowly to the subthread here, which is about firing someone who gives an ultimatum in the abstract. I don't know enough about the specifics of Timnit/Google's situation to pass judgment. (I'm also an employee there, so doing so would be unwise and a potential violation of confidentiality rules if I did know anything.) To me I'm filing it under "Everybody sees through their emotions, and different people will have different perceptions of what actually happened and what people actually intended."
