Written notification from an employee to his/her employer, indicating that a work-connected injury or injury has occurred. For accidental injuries, notice must be given no later than 30 days after the accident; the Board must excuse a failure to give notice on the grounds that a) for some reason, notice could not have been given; b) the employer had knowledge of the accident; or c) the employer’s case has not been prejudiced. In cases involving occupational diseases, the time period for notice is 2 years from the date of disablement or from the date when the employee knew, or should have known, that the disease was due to the nature of employment.
