I worked for the company for 10 years, followed all their rules & regulations, I was unjustly accused of 1 violation with no proof and terminated.

In the United States, employment is on an "at will" basis. That means that your employer can terminate your employment at any time for any reason or no reason at all, even an unfounded or imagined reason. If you have wrongfully been denied unemployment benefits, you are entitled to a hearing and to an appeal. Good luck with them -- if you can prove the charges are unfounded, you have a shot at receiving those benefits. Your employer is not legally responsible for your foreclosure status.
