72-419. DETERMINATION OF AVERAGE WEEKLY WAGE. Except as otherwise provided in this law, the average weekly wage of the employee at the time of the accident causing the injury or of manifestation of the occupational disease shall be taken as the basis upon which to compute compensation and shall be determined as follows:
(1) If at such time the wages are fixed by the week, the amount so fixed shall be the average weekly wage.
(2) If at such time the wages are fixed by the month, the average weekly wage shall be the monthly wage so fixed multiplied by twelve (12) and divided by fifty-two (52).
(3) If at such time the wages are fixed by the year, the average weekly wage shall be the yearly wage so fixed divided by fifty-two (52).
(4) (a) If at such time the wages are fixed by the day, hour or by the output of the employee, the average weekly wage shall be the wage most favorable to the employee computed by dividing by thirteen (13) his wages (not including overtime or premium pay) earned in the employ of the employer in the first, second, third or fourth period of thirteen (13) consecutive calendar weeks in the fifty-two (52) weeks immediately preceding the time of accident or manifestation of the disease.
(b) If the employee has been in the employ of the employer less than twelve (12) calendar weeks immediately preceding the accident or manifestation of the disease, his average weekly wage shall be computed under the foregoing paragraph, taking the wages (not including overtime or premium pay) for such purpose to be the amount he would have earned had he been so employed by the employer the full thirteen (13) calendar weeks immediately preceding such time and had worked, when work was available to other employees in a similar occupation.
(5) If at such time the hourly wage has not been fixed or cannot be ascertained, the wage for the purpose of calculating compensation shall be taken to be the usual wage for similar services where such services are rendered by paid employees.
(6) In seasonal occupations that do not customarily operate throughout the entire year, the average weekly wage shall be taken to be one-fiftieth (1/50) of the total wages which the employee has earned from all occupations during the twelve (12) calendar months immediately preceding the time of the accident or manifestation of the disease.
(7) In the case of a volunteer emergency responder, the income benefits in the first fifty-two (52) weeks shall be based on the average weekly wage in his regular employment or sixty-seven percent (67%) of the current average weekly state wage, as determined pursuant to section 72-409(2), Idaho Code, whichever is greater.
(8) If the employee was a minor, apprentice or trainee at the time of the accident or manifestation of the disease, and it is established that under normal conditions his wages should be expected to increase during the period of disability that fact may be considered in computing his average weekly wage.
(9) When the employee is working under concurrent contracts with two (2) or more employers and the defendant employer has knowledge of such employment prior to the injury, the employee’s wages from all such employers shall be considered as if earned from the employer liable for compensation.
(10) When circumstances are such that the actual rate of pay cannot be readily ascertained, the wage shall be deemed to be the contractual, customary or usual wage in the particular employment, industry or community for the same or similar service.
(11) In the case of public employees covered under section 72-205(6), Idaho Code, the income benefits shall be based on the greater of the average weekly wage of the employee’s civilian employment and pay computed for one (1) weekend drill in a month, or full-time active duty pay fixed by the month as provided in section 46-605, Idaho Code.
