WRITE EVERYTHING DOWN!!! It would amaze you how many times the employer/work comp carrier will seize on one tiny inconsistency between statements by you to hammer you to death. Notice of the injury, according to the applicable statute, is supposed to be made IN WRITING AS SOON AS POSSIBLE AFTER THE INJURY. There are many exceptions, but PLEASE don’t put yourself in a position to damage your claim at the beginning because you couldn’t find a pen and paper.
