They didn't actually have performance indicators, nor any poor performance data. When she asked for their evidence, they said they could get it later. In my head that translates to "We don't actually have the data."
"We can talk about that later."
"We can't go into specifics at the moment."
"This isn't the form, or the situation where we can go into detail."
I love her response:
"But then when? If it's not right when I'm getting fired then it's certainly not going to be after when I'm no longer part of the company."
