I too have just been let go from my company - my time on FMLA has expired (12 weeks) In California, an "at will" state, without the luxury of a contract I don't seem to have any recourse. I've been told that if within one year I am able to return to work, I can check to see if there are open positions. I held a position of senior manager in a manufacturing company.
I've since begun the process of applying for permanent disability, determined to be appropriate by my doc, but this can take up to 18 months and if approved will result in an income equal to 1/4 of what I'm accustomed to making - not even enough to meet the mortgage.
Good luck to you.
