I was just reading this discussion concerning the use of "fired" by your former employer. While I am not 100% certain of the legal implications of SI refering to you as "fired", because in most uses it refers to "Fired for Cause" not merely "laid off" I would think you would have good cause to file suit (as many have) for defamation, slander and/or Libel. As it is now having an effect on your present situation, you should have no problem finding an attorney to take the case. Unless you have already done so.
