Is this legal? I’m worried as I can’t really plan the future or find another job if they suddenly change their minds. Surely it should be binding on both sides?

I set up accounts with a fortune 500 company for my future and while they were setting up the acounts somebody got thier hands on all my paperwork, checks, Social Security number and made blank checks with all the information that I provided to this firm. We recieved a phone call from the police in a different state letting me know that all this paperwork was found by a thief and he had all my information. What are my rights and where do I find a lawyer to represent me for this horrific negligance??
