My employer forged my signature on a letter that he sent to his mortgage company to co-sign on a car for a friend. I have a copy of the letter and have spoken to the both my boss and the mortgage company itself. My boss stated that the reason he did it was because I knew they were talking to the mortgage company and knew what was in the letter. I did know that they were talking to the mortgage company as I was asked to verify his employment with us. However I was not aware of any letter or its contents until I heard a voicemail from the mortgage company asking me to call them back. When I talked with them they asked me about the letter and I stated that I was not aware of it. When I got a copy of it I saw that everything in the letter completely contradicted what I had stated to the mortgage company on the phone. Now my question is what I can I do about this, should I file a suit, and if so what kind?
