What can I do if someone forged my signature

I started a new job and found a piece of paper that was faxed to all of my previous employers asking for a copy of my prior employment history and on the paper that was faxed it said I here by give you permission to release prior work history and someone in the office of my new job signed my name to the paper. they never even asked me to sign it, they took it upon themselves to sign my name. Do I have any legal rights ?
