For a workers' compensation claim arising after May 5, 2015, if an employee was working for more than one employer, the employee's earnings used to calculate the employee's average weekly wage in §§ 62-4-24, 62-4-25, or 62-4-26 shall include the amount of compensation for the number of hours commonly regarded as a day's work for each employer in which the person was concurrently employed at the time of the person's injury; however, an employee's earnings from concurrent employment are aggregated only if the injury occurred when the employee was actively working in the concurrent employment and when the injury prevents the employee from performing the employee's duties at the employee's other concurrent employment.
