Yes. In general, an injured worker is required to provide notice of his or her injury to their employer with 45 days of the accident.  However, it is always to an injured worker’s advantage to provide notice as soon as possible.  With repetitive trauma cases, such as carpal tunnel, it often is difficult to determine when the injury occurred in order to calculate the 45 day notice period.  It is crucial you discuss your injury with an attorney in a timely manner to ensure that you are aware of the notice requirements.
