The number one reason employers fight workers comp claims is that there is no eyewitness to the injury. Should you find yourself in this situation, don't focus on the lack of eyewitnesses, that cannot be controlled. Focus on what you can control, reporting your injury quickly and accurately to your employer. We recommend doing this in writing so you have a record. You will also want to be sure that any later insurance investigation or recorded statement you are asked to give will accurately reflect what happened when you got hurt.
