Okay, the downside of the whole sending them too much stuff deal is that they will enter all that into evidence,and may say that you have already presented your evidence, not give you an opportunity to present it adequately. So when you get into the hearing, you will need to have a copy of what you presented to them, but ask if you can "present" instead of just having it serve as your appeal. So then you will need to very succinctly, begin with what you feel begun your situation. In other words, start with the precipitating incident before you filed your grievance with EEOC. (Not in too much detail, just say something like, "The reason I was forced to quit my job goes back, I believe, to what happened in Jun, 2008. I was groped on the elevator by my supervisor, George Blah. I spoke with HR, and then I filed a grievance with EEOC concerning this incident.") Go through it quickly.
Then, how you were given a letter, and you and the EEOC representative worked with the company. How you understood that you were not to be subjected to retaliation for filing this complaint. How you had worked all these years without complaint about your performance, and how now you seemed to be having some incidents that were very retaliatory. (Evidence of these would be helpful.)You did not receive a bonus which everyone had been granted. How you tried to work out this situation with your company before you decided to resign. (Evidence of this would be helpful.)How you gave them every possible opportunity to resolve the situation. How finally, you gave your notice that you were quitting to your supervisor.
Hopefully, they will let you give a verbal presentation of this type, instead of just putting the junk you sent them on record.
I have no idea whatsoever about whether you should tell EEOC about the unemployment hearing. They will have NO connection with the unemployment appeal, and will have no idea whether you are approved or not. You are, of course, going to tell the appeals referee about the EEOC case. I assume that a great deal of the material you sent in was the stuff from EEOC.
There is no way you can present your case in a letter. Therefore, you should ask to "go through" the letter if they want to use it in the hearing. All the parties will be sworn in, and you will present your case, and then the employer will be able to present his case. The referee will ask questions concerning the situation if they do not get what they need from either of you.
I do not think you need to bring in a witness in particularly a character witness. This would not help your case at all. The person who was standing there and actually heard what the supervisor said to you and what you said to them when you told them you were going to quit might be an okay witness, but otherwise, they may have very little to contribute.
Keep filing for weeks of unemployment, even though you will not get any more weeks paid unless you win the appeal.
They usually do appeals in some office close by. I do not think KY requires you to report to the offices at the capitol. I'd say the closest large Career Center office is where they'd come to. They'll let you know soon.
