HR doesn’t squirm because they are lying. They squirm because they minimize lawsuit surface area as much as possible. I have been on the giving end of performance layoffs in big corps and there is an extremely strict script you have to stick to (both HR rep and me as the manager).
I saw the video you’re referring to and it’s completely unsurprising they clam up further when she became confrontational. You’re not gonna talk your way out of a termination unless you have some pretty hard evidence it was for something illegal.
That’s just what getting fired looks like and people don’t often get to see the process so cloudflare “became famous”.
How is obviously lying about the layoff reason minimizing the lawsuit area? It's ripping it wide open I'd think.
