How much experience do you have managing people?
In my 15+ years doing so, I’ve never heard or seen a situation in a reasonable organization where someone gets on a list like this (intentionally, as compared to their manager screwing up by not having a conversation with them before it is clearly a huge problem to everyone else) without knowing they are going to get on a list like this if they don’t improve.
I have heard it at many places that are flogging employees or using scare tactics to get every cent worth of value they can put or people before they burn out and get thrown on the rubbish bin.
