It is a small company, 3 employees. I'm the only one with my job title and the only one needed. The building we work in isn't even big enough for a 4th person. So yeah, he's replacing me. Hasn't told me but his job posting said he's looking to have someone new within 2 weeks. So he could have given me a 2 week notice but will probably just fire me. All of this because I called him out on unethical medical practices. I was even nice about it and just expressed my concerns but he's been short with me ever since and now this.
