I have not read the answers to your posts but...
You are being discriminated against due to be handicapped. BAD EMPLOYER! Keep documents, journal and put everything you can in writing. According to the information I have found out if the company has more than 20 employees they have to make accomodations for you.
I went through the same problems when I returned in Jan and started emailing all questions and problems through my human resources deparment. It didn't do much good but they are leaving me alone at this point. I was only able to return to 10 hours a week and work from home. I have been told if I'm not 100% the next school year I'll be let go and am in the middle of applying for social security.
I talked with the EEOC and told them what was going on and they recommended I document everything. Emails are great because they can be used in court. They also suggested I file a complaint which I chose at this point not to do I just wanted to know what my rights are. I also found some books that go into detail about handicapping conditions.
You might want to apply with vocational rehab as they will provide sensitivity training, an interpereter, make accomodations in special desks, phones, etc so that you can maintain your employment. You can also find a good doctor who will listen and sign you out on stress related disabitlity due to your job conditions. Don't let them force you out.
DOCUMENT, DOCUMENT, DOCUMENT...I can't stress that enough. If I have a verbal conversation with my boss I email her a paraphrased version so that I have it all on record. Especially since I'm a remote employee and there would be no witnesses if it comes down to a he said she said thing. If the other employees are acting that way you'd be in the same situation.
I can begin to tell me how much what they are doing angers me. I've worked with handicapped kids all my life and there are laws on the books to keep people from doing this. You'd think the government would understand this.
They HAVE to make accomodations. Let human resources know that you are DISABLED. Know one wants to be disabled but..the reality for most of us is we are and employers need to understand that and make concessions. They can move your desk around. Heck I'll even come move it for you let me at em!
