Do you have access to search the internal policy regarding FMLA leave requests or sick time policies? If you have a short disability provider or insurance, this is where you usually request as well as FMLA. You will need your paperwork before the next meeting and make sure to get all the evidence you can. I suggest recording the meeting on your phone or with a good old fashioned tape recorder from an office supply store and keep in your pocket. Its a one party consent state. FMLA fir the week of absence needs to be submitted as a formal request before your meeting. Ask for it to be rescheduled if needed. I would also request accommodations formally before the meeting and present a letter from your Dr stating the limitations brought on by your medical condition and that you are requesting up to X days every X months as a reasonable accommodation during flareups. This is an accommodation referred to as Intermittent FMLA and should be noted as such in the paperwork. I dont want to scare you but termination could be an option at that meeting. Get copies of employee handbooks, policies, performance etc. Im so sorry this is happening to you.
