Hi Roma,
Since you're still working, but starting to experience trouble with your job, you should check up on what kind of disability insurance you have. You may have short and long term disability through your work, state disability, and Social Security Disability. You can ask HR or check your paystub. If you see little deductions marked STD, LTD, and FICA, then you have short term, long term and SS disability coverage available.
There are only 5 states that have state disability, I'm not sure if Illinois is one.
If it comes down to it, don't quit your job and don't go to a part time schedule. Go out on disability if possible. Disability is based on a percentage of your income, so if you go part time, it will only be 30-60% of your part time salary, instead of your full time salary.
i have short and long term disability, but i think for now i can still work and even if i wanted to stop working i wouldn't be able to, i have too many bills and rent to pay and my contract does not end till May so i will have to though it out till May at least and then move somewhere cheaper so i can maybe start working less hours, but really if i stop working i would see no more reason for me to be here, like i said before i have no friends no famili around here really my only distraction is going to work, i think i would get much worse if i was home all the time..anyways thanks a lot for your help.
