You need to go talk to a worker's compensation attorney. Your question implicates both worker's compensation and unemployment compensation law, but I believe in this instance worker's compensation law is primary. If he is retaliating against you for filing a claim that is not legal. There may be other issues also. Set up some appointments with WC attorneys to find out your rights.

You have fallen into a common trap used by almost all employers and their WC carriers. You must get a WC lawyer immediately or you will have no job and no case.
If you think you can demonstrate that his decision to stop paying you was substantially (but not necessarily totally) motivated by the fact that you claimed workers' comp benefits, then you should talk to an attorney about suing for w/c retaliation, which would be a court proceeding outside of the w/c system for separate damages. Also, note that the employer's failure to pay wages owed is usually grounds to separate from the employer without jeopardizing entitlement to unemployment comp benefits. You should definitely seek out an employment attorney with w/c experience to discuss u/c benefits, a possible unpaid wages suit, and the status of your w/c case.
