Except as otherwise provided in this section, the average weekly wage of a covered employee shall be computed by determining the average of the weekly wages of the covered employee: when the covered employee is working full time; and at the time of: the accidental personal injury; or the last injurious exposure of the covered employee to the hazards of an occupational disease. For purposes of a computation under paragraph (1) of this subsection, wages shall include: tips; and the reasonable value of housing, lodging, meals, rent, and other similar advantages that the covered employee received from the employer. If a covered employee establishes that, because of the age and experience of the covered employee at the time of the accidental personal injury or last injurious exposure to the hazards of the occupational disease, the wages of the covered employee could be expected to increase under normal circumstances, the expected increase may be taken into account when computing the average weekly wage of the covered employee under paragraph (1) of this subsection.

If the covered employee earned weekly wages from another employment that exceeded the weekly wages the covered employee earned from the employment in which the accidental personal injury occurred, the average weekly wage of the covered employee shall be based on the weekly wages the covered employee earned in the other employment. If the covered employee earned weekly wages from two or more other employments and, for more than one of such employments, the weekly wages earned by the employee exceeded the weekly wages of the covered employee from the employment in which the accidental personal injury occurred, the average weekly wage of the covered employee shall be based on weekly wages of the employment where the employee earned the highest wages.
