(a) Computation of wages shall include, in addition to salary, hourly pay, or tips, the reasonable value of food, housing, and other benefits furnished by the employer without charge to the employee which constitute a financial benefit to the employee and are capable of pecuniary calculation.
(b) Unless the contrary appears, it is assumed that a normal workweek is five days, that the normal workday is eight hours, and that the employee’s daily wage is one-fifth of the weekly pay. Fractional parts of a day shall be credited proportionately in computing the daily wage. For example, the daily wage of a five-and-one-half day worker is the weekly wage divided by 5.5.
(c) If the employee has similar concurrent employment the wages paid by all similar concurrent employers shall be included in calculating the average weekly wage.
