Yes. It is most important that you act without any delay in preserving your legal rights. While workers' compensation laws vary from jurisdiction to jurisdiction, certain statutes require that you provide actual legal notice to you employer or its insurance company of your disease within days of your diagnosis or knowledge that your condition is related to your employment. Other benefits must frequently be timely requested, including medical treatment and permanent or partial disability benefits. Employers usually deny claims and terminate benefits without notice so it is very important that you obtain legal guidance immediately.
