Hello again and thank you for the information it was helpful. You have a few options available to you and your best bet would be to sit down with a local employment law
attorney who, after hearing all of the facts, can put together a plan of action with you in a way that best addresses what you want to have happen. But in any event, with or without an attorney you will need to file a discrimination
complaint with either the SC Human Affairs Commission or the EEOC
. Your attorney might also recommend that before you do so, you write a letter to HR and copy Corporate Legal with a synopsis of what you experienced and your history with the company and your concerns that your age and/or your disability played a roll in the non-hiring decision and that you would like for them to reconsider their decision. (You might not want to do that though if you really don't want to work for them anymore.) But in any event, the letter is not necessary but it is often good to gel the facts for future use in your complaint and a possible discrimination suit.
Once you have filed your complaint with the State or the EEOC, you have two choices. Either to wait for them to investigate your allegations and try to resolve the issue, or just immediately file suit. Again though, your attorney will help you decide that. Just as a point here though, if you have limited funds, you might want to let the agencies I mentioned investigate and try to resolve the issue before you decide to litigate so that you will have the benefit of using what they learned to help you with your litigation should you decide to go through with it after they reach their conclusion.
Please let me know if you need any clarification. I would be glad to assist you further if I can.
