RA and performance improvement plan

I was put on a performance improvement plan on 15 May. This came after about 6 months of issues with my boss. I work at a VA hospital and had been experiencing what I perceived as a hostile work environment. In November 2025 I emailed the hospital leadership, VISN leadership and my congressman regarding what I perceived as a hostile work environment.

In Dec 2025 my supervisor put me on a professional development plan (PDP), I am not exactly sure if that is a real thing. It was vague and it has things like improve communication, use something called CAPA to ask him questions and couple other vague items. It stated there would be weekly meetings with a 60 and 90 day check in. There were a total of 5 meetings between 19 Dec when it started and the end of March when he gave me a notice of poor performance. During the whole time of the PDP he kept adding things and changing requirements for other things he requested I do.

The end of February I filed a complaint with the Office of Resolution Management for hostile work environment, discrimination and reprisal. On 21 April my complaint was accepted for a formal investigation and I am awaiting the assignment of an investigator.

On 15 May my supervisor put me on a PIP. I don’t think the PIP is valid because it only states what he perceives are my deficiencies, it has no standards as to what constitutes a success PIP, it has no training, and most of the deficiencies (99%) are not on my performance plan. I contacted HR and they stated it was valid. I informed them of my ORM complaint and they said that an ORM complaint doesn’t matter. I submitted the PIP to ORM as an amendment and it was accepted. HR is aware of this.

In November 2024 I was diagnosed with ADHD and early in 2025 I requested the paperwork for reasonable accommodations. At that time my psychiatrist would not sign the paperwork. I contacted the RA coordinator and asked her what are my options. I believe I also sent her the paperwork. She never replied. My current supervisor was the one who gave me her contact information but at the time he was not my supervisor. He became my supervisor in May 2025.

I recently found out that I could submit the paperwork without my psychiatrist signing it. Today I submitted the paperwork without my medical diagnosis and also my VA decision letter that upgraded my mental health rating from 70% to 100%. The rating is for persistent depressive disorder with anxious distress.

My question is how does the RA request affect my PIP. I have every reason to believe that my supervisor will initiate the paperwork to fire me once the PIP is over in August. I don’t know the exact process to fire me but I do know I can rebut it.
