Why is Brittney’s video not a reliable impartial account? Also note that nothing she says about her performance and feedback is in any way disputed during the call. They had nothing to say to the contrary.
We don't actually know what her manager said to her during all her one to ones. We don't know what feedback she was receiving. Just because the person on the other end of the call did not dispute any of the things she raised, it does not mean she was correct and not biased.
We also see from Matthew Prince's reply to the video that he is also an unreliable participant as he is suggesting that a manager would always be involved in redundancies, and we can see from the video that was not the case.
HR is not going to argue on a call like that, so the viewer will always see a one sided account. The decision has been made, and not by them. They likely do not even know or have access to that information and are given a list and told "fire these people today." She could have come to work drunk, and you would still not hear about it on a call like that. I don't like it either, but it is the way things go at big corps.
