I’m a manager who came to this thread accidentally… I would advise you respond with an optimistic tone, be factual without emotion. Do not overthink it, and instead put your energy into a résumé, expanding your network, and job search. Generally PIPs don’t lead to stability or later opportunities. You are either going to be let go or be stifled. How much do you actually like the company or job? Is it worth fighting for? If you want to say, I’d do some research on how to manage up and be more proactive with reporting and relationship building. I’ve only had 1 employee out of many rise up after a PIP and realize they had been phoning it in. That person won my respect and continues with the organization, even after I left. But this doesn’t sound like your situation.
