In computing the 13th month pay of its employees, Liwayway Company (LC) includes as basis not only the regular base pay but also the cash value of unused vacation and sick leaves. LC had been implementing this method for two years when it suddenly announced that the method was erroneous and would therefore be discontinued. May LC lawfully discontinue using this method? Discuss.
Suggested answer only. Not an official answer and not legal advice.
Yes, LC may lawfully discontinue using this computation method.
Under Presidential Decree No. 851 and jurisprudence (Societe Internationale v. Huliganga), 13th month pay is computed based solely on basic salary, excluding unused leave credits. Erroneous grants do not ripen into a binding company practice under the non-diminution rule unless shown to be deliberate and intentional over a long period.
Here, LC's inclusion of unused leave cash values for two years was a result of excusable error rather than a deliberate policy. Lacking intentionality and sufficient duration to constitute a voluntary practice, correcting the mistake does not violate the rule on non-diminution of benefits.
Therefore, LC can lawfully discontinue the erroneous method.

1. 13th Month Pay
Under Presidential Decree No. 851 and its implementing rules, 13th month pay is computed based solely on the employee's basic salary earned within a calendar year. Basic salary includes all remunerations or earnings paid by an employer for services rendered, but excludes fringe benefits, allowances, and profit-sharing payments. Unused vacation and sick leave cash equivalents do not form part of the basic salary for 13th month pay computation. Therefore, statutory requirements do not compel an employer to include leave conversion cash values in computing an employee's mandatory 13th month pay.
2. Non-Diminution Rule Exceptions
Article 100 of the Labor Code prohibits the elimination or diminution of employee benefits. However, for a company practice to ripen into a demandable benefit under the non-diminution rule, the grant must be voluntary, deliberate, and practiced over a long period. In Societe Internationale v. Huliganga, the Supreme Court held that benefits granted through mistake or error do not give rise to a vested right. Correction of an erroneous benefit computation does not constitute an unlawful diminution of benefits because error creates no vested rights in favor of employees.
3. Company Practice Elements
To establish a binding company practice, the employee carries the burden of proving that the grant of benefit was intentional, consistent, and practiced over a considerable length of time. A brief two-year period characterized by administrative error lacks the requisite duration and deliberate intent necessary to transform an overpayment into an enforceable voluntary practice. When an employer promptly discovers an accounting error and moves to correct the computation method, the employer acts validly within its management prerogative without violating Philippine labor laws.
