After an accident, companies often try to force injured workers to sign an agreement or release in exchange for a small payment. You should never sign anything without talking to a skilled attorney. Most often, the insurance companies are really trying to pay you the least amount possible. They will also require you to give up your legal rights later on.
For this reason, it is imperative that after being involved in a personal injury accident you retain legal representation immediately. You should not sign anything, or give any kind of a statement, before consulting the situation over with an injury attorney.
Having a skilled lawyer on your side will help you avoid jeopardizing your case. Your employer will have people protecting his back—make sure you have someone protecting yours!
