Philippine Duplicators v. Tupas

Summary

Philippine Duplicators, Inc. challenged the computation of 13th month pay for its salesmen who receive fixed salary plus sales commissions. The company argued that commissions should be excluded from the 13th month pay base, contending that administrative bulletins including commissions exceeded statutory authority. The Supreme Court unanimously rejected this argument, holding that sales commissions constitute part of 'wage' or 'salary' under Labor Code Article 97(f) and are not mere fringe benefits or allowances. The Court emphasized that commissions represent direct remuneration for services rendered and form the bulk of salesmen's compensation. Administrative construction by labor officials deserves great respect in statutory interpretation. The decision established that 13th month pay for employees receiving fixed wage plus commissions must be computed on total annual earnings, equivalent to one-twelfth of both fixed wage and sales commissions combined.
