Yes it makes no sense, if he’s the fall guy then what will happen when h3 goes, and he’s admitting there is performance measures, and he has to email each week to say he’s done his tasks, which is standard pip, it’s micro management and you break it down and get rhe employee to confirm they’ve done it.
no one puts someone as excellent as he says he is, on a pip, how would you even create rhe improvement measures.
so he is telling the op how brilliant he is. Saving the department, doing multiple people’s jobs. How shit his boss is, when in reality it would seem he is under performing and has been for some time. Hence the pip.
so the op needs to get gently past his ego and embarassment and get to the truth of it, and this will give her a fair idea of why there is now an hr meeting.
the fact he says the manager went cold for the last two weeks, could indicate he’s not been performing on the pip either and he’s preparing the op for what may happen. The fact he even asked if it was disciplinary says he felt it might be,
it won’t be termination, but I’d assume this is a serious conversation about his lack of performance.
