My employer keeps telling me to quit my job. He keeps telling me I am not doing my job ccorrectly and I should quit. I have been employed with the same person (a sole practitioner) for 18 years. Never have I been put on notice. I work in a very TOXIC work environment. What are my rights?

Thank you for your question. First things first - do not resign until you have spoken to a lawyer. I would also suggest that you write to him to broach the toxicity of the workplace and invite him to speak to you in further detail about any alleged "performance issues". If you feel as though the environment is becoming unbearable, you may have a claim for constructive dismissal - which could be significant, given that you have been there for 18 years. Given the potential scope of your entitlements, I would strongly recommend speaking to a lawyer.
