Worker compensation law, like most legal issues related to employment, can change relatively quickly. That's why, when you file a worker compensation case, you need a lawyer with deep experience in the field, and the knowledge to get the job done.
It can't hurt to educate yourself on the worker compensation legal process once you've hired a lawyer to represent you. Ask them to send you copies of all motions and documents they file, just so you can keep track of things. If nothing else, it'll keep them on their toes.
