Rant on the boss

I am blue right now. But I am trying not to be. I am in danger of being fired from my job. I was" written up" for some documentation errors that my supervisor found in my absence while I was recovering from my surgery. The next step is either a "written plan" or termination, depending on my next infraction. My supervisor has been on my back for a year and a half. She has been breathing down my neck for small things. She has been calling me into her office and yelling at me, being snide, sarcastic and hostile. She has been angry about having to accomodate me in the workplace. Now she has to accomodate me more because she tried to tell me I couldn't have anymore time off, for medical appointments, of which I have 3 coming up. She refused to negotiate that, telling me I had to go at 6:30 a.m. or 6 p.m. even if the offices weren't open, I had to negotiate that with them. I told her that was illegal. She got very upset, leaving the office in a huff to talk to the administrator. They came up with a plan whereby now I give all my appointment times to the admistrator and have to make up the time, which is what I offered to do with my supervisor, and she declined. God that woman! She has been on me for a year and a half. I am speaking with a lawyer tomorrow. This is a facility that works with people with severe disabilities for god's sake! I have pages and pages of notes of how she has treated me: dates and statements and how they were made, etc. Life with a disability is never boring! It is filled with frustrations and pitfalls of all kinds.
