If I have been turned down for worker's comp because my employer denied I was injured on the job, can I sue him in a civil court?

In Virginia if you have an accident on the job and the claim is denied by your employer, your remedy is to file a claim with the Virginia Workers' Compensation Commission. That Number is 1-877-664-2566.  After you file a claim, the Commission will set a date for a hearing in front of a hearing commissioner. It then will be your word against your employer as to whether or not you were/were not injured on the job. It would be wise to consult with an attorney about this matter. You have two (2) years from the date of your accident to file this Claim for Benefits with the Commission.  You can only "sue" your employer for the injury if the employer does not have workers' compensation insurance.
