The WPL defines “wages” as “direct monetary compensation for labor or services rendered by an employee, where the amount is determined on a time, task, piece, or commission basis.” N.J.S.A. 34:11-4.1(c) (emphasis added). Under that definition, compensating an employee by paying a “commission” for “labor or services” always constitutes a wage under the WPL. Therefore, a “commission” under the WPL cannot be excluded from the definition of “wages” as a “supplementary incentive.”
