Court reviews the Commission’s conclusions of law de novo.” Deseth v. LensCrafters, Inc., 160 N.C. App. 180, 184, 585 S.E.2d 264, 267 (2003). N.C. Gen. Stat. § 97-30 governs the calculation of partial disability compensation and states in relevant part: Except as otherwise provided in G.S. 97-31, where the incapacity for work resulting from the injury is partial, the employer shall pay, or cause to be paid, as hereinafter provided, to the injured employee during such disability, a weekly compensation equal to sixty-six and two-thirds percent (66 2/3 %) of the difference between his average weekly wages before the injury and the average weekly wages which he is able to earn thereafter[.] N.C. Gen. Stat. § 97-2(5) (2009) defines “average weekly wages” as 9, 146 S.E.2d 479, 486 (1966) (<HOLDING>), overruled on other grounds by Derebery v.
holding that the definition of average weekly wages and the range of alternatives set forth in the five methods of computing such wages as specified in the first two paragraphs of ncgs  9725 do not allow the inclusion of wages or income earned in employment or work other than that in which the employee was injured holding that where the employment of the injured employees was the occasion of the injury the injuries arose out of employment holding that law enforcement commission was a benefit of employment holding that in determining plaintiffs average weekly wage pursuant to nc gen stat  9725 the commission had no authority to combine his earnings from the employment in which he was injured with those from any other employment holding that the scope of the average weekly wage definition is not unlimited and concluding that it excludes fringe benefits
