> Have you tried talking to your manager about your performance and future at the company?

I did. I go well out of my way (and comfort zone) to make very open conversations with him. I can't get any answers or feedback at all related to my future. He says my performance is not meeting his expectations and points to multiple examples -- subjective but he rationalizes and sells it well.

I believe he wants to get rid of me but needs corporate buy-in to make it happen. I've never been a manager before so I could be wrong.
