Every case is different and many factors affect the answers to what appear to be simple questions.
Therefore, to get answers to questions regarding a specific case, you should consult an attorney who specializes in the area of workers' compensation. My employer denied my claim for workers' compensation benefits. I think I am entitled to benefits because I can't work. Although the law permits a claimant to represent himself, under most circumstances you should hire an attorney to handle petitions before a Workers' Compensation Judge. The employer and insurance company will always have an experienced attorney representing their interests.
