Undertime Philippines: Art. 88 No-Offset Rule and Pay

Last materially reviewed: August 15, 2026

Payroll cuts two hours from your pay for leaving early on Tuesday. On Thursday you stay three hours late. When the payslip arrives, the overtime has quietly vanished — cancelled against Tuesday. That is not a rounding convention or a company policy choice. It is prohibited by Article 88 of the Labor Code, and the reason is arithmetic: offsetting lets an employer erase premium-rated hours using straight-rated ones, so the employee silently loses the overtime premium.

This guide covers what undertime is, why the no-offset rule exists, the arrangements that are lawful and are often confused with offsetting, how the deduction should actually be computed, and what to do when a payslip does not add up.

Direct Answer

Undertime is time an employee was scheduled to work but did not. Under Article 88 of the Labor Code, undertime on one day cannot be offset by overtime on another day. An employer may decline to pay for hours not worked, but it must still pay overtime separately, at the premium rate, for hours actually worked beyond eight in a day. Article 88 adds that letting the employee take leave on another day does not excuse the employer from paying that additional compensation either.

Decision Snapshot

Question	Practical answer
Who this applies to	Employees covered by the hours-of-work rules in Book Three, Title I of the Labor Code. Article 82 excludes government employees, managerial employees and managerial staff, field personnel whose hours cannot be determined with reasonable certainty, dependent family members of the employer, domestic workers and persons in the personal service of another, and workers paid by results under applicable regulations. Coverage turns on actual duties, not job title.
Core rule	Article 88 provides that undertime work on any particular day shall not be offset by overtime work on any other day, and that permission given to the employee to go on leave on some other day of the week shall not exempt the employer from paying the additional compensation required in this Chapter.
Main boundary	The rule bars offsetting; it does not force an employer to pay for hours nobody worked. Wages for unworked scheduled hours are simply not earned, which is a different thing from an unlawful deduction from wages already earned. A compressed workweek is also not offsetting: under DOLE Department Advisory No. 02, Series of 2004 the normal workday may be lengthened beyond eight hours, but not past twelve, without overtime premium, provided the weekly total stays within 48 hours, the arrangement is voluntary, and no existing benefit is diminished.
Key evidence	The published work schedule, daily time records or biometric and system logs, approved leave and schedule-change records, the overtime authorization or approval for the day in question, and the payslip and payroll register showing the hourly rate and every adjustment applied.
Deadline / rate / period	Overtime beyond eight hours in a day is paid at the regular wage plus at least 25 percent, and at least 30 percent on a rest day or holiday, under Article 87. Any undertime deduction must use the correct hourly rate and accurate time records. Money claims arising from the employment relationship generally prescribe in three years from accrual under Article 306, formerly Article 291.
First next step	Put the two dates side by side on the payslip. If overtime hours you actually worked were reduced or cancelled because of undertime on a different date, that is the Article 88 violation — ask payroll in writing for an itemized computation showing the hourly rate, the undertime hours deducted, the overtime hours paid and the premium rate applied to each.

Key Takeaways

Offsetting is prohibited outright. Article 88 does not say “unless company policy provides otherwise.” There is no contractual workaround, because the arrangement would waive a statutory premium.
The employee loses money in every offset. Undertime is deducted at the straight hourly rate; overtime is earned at that rate plus at least 25 percent. Cancelling one against the other destroys the premium.
Not paying for unworked hours is lawful. The no-offset rule is about the overtime premium, not about paying for time nobody worked.
Leave on another day is not a substitute either. Article 88’s second sentence closes that door explicitly.
A compressed workweek is a different thing. It restructures the normal workday in advance under DOLE conditions; it does not cancel one day’s shortfall against another day’s excess after the fact.
Approved paid leave is not undertime and should not be recorded as such.

Legal Basis

Statute. Article 88 of the Labor Code states in full: “Undertime work on any particular day shall not be offset by overtime work on any other day. Permission given to the employee to go on leave on some other day of the week shall not exempt the employer from paying the additional compensation required in this Chapter.”

The premium it protects. Article 87 provides that work may be performed beyond eight hours a day provided the employee is paid, for the overtime work, an additional compensation equivalent to the regular wage plus at least twenty-five percent thereof. Overtime on a rest day or holiday carries at least thirty percent.

The baseline day. Article 83 sets normal hours of work at not more than eight hours a day, which is what makes an hour the ninth hour and therefore overtime.

Who is covered. Article 82 defines coverage for the whole of Title I and lists the excluded categories.

What Undertime Is, and What It Is Not

Undertime is the gap between the hours an employee was scheduled to work on a given day and the hours actually worked. It is a measurement, not a penalty and not a disciplinary finding. On its own it produces one consequence: the unworked hours are not compensable.

Three things are frequently filed under “undertime” that do not belong there:

Approved paid leave. If the absence is covered by an approved leave that the applicable policy makes paid, the hours are paid. Recording them as undertime converts a benefit the employee already holds into a deduction.
A lawful schedule change. If the employer moved the shift, the employee did not fall short of it.
Tardiness treated twice. Late arrival already shortens the compensable day. Adding a separate fixed monetary fine on top of the unworked time is a distinct charge that needs its own lawful basis.

The No-Offset Rule and the Arithmetic Behind It

Article 88’s first sentence is one line long and admits no exception on its face. The reason becomes obvious once the two rates are written down, because undertime and overtime are not priced the same.

Take an employee on a daily rate of ₱750 for an eight-hour day.

Hourly rate: ₱750 ÷ 8 = ₱93.75
Two hours of undertime on Tuesday: ₱93.75 × 2 = ₱187.50 not earned
Two hours of overtime on Thursday at the regular wage plus 25 percent: ₱93.75 × 1.25 × 2 = ₱234.38 earned

Cancel one against the other and the employee has surrendered ₱234.38 of premium-rated pay to settle a ₱187.50 shortfall. The difference — ₱46.88 — is precisely the overtime premium, and it disappears into the offset. Multiply that across a payroll and across a year and the scale of the leakage becomes clear.

This is why the prohibition is absolute rather than a default that a contract can vary. An agreement to offset is an agreement to waive the statutory premium on hours already worked.

Why Leave on Another Day Does Not Count Either

The second sentence of Article 88 anticipates the obvious workaround. An employer that cannot cancel Thursday’s overtime against Tuesday’s undertime might instead offer the employee a day off next week and treat the matter as settled.

Article 88 forecloses this: permission given to the employee to go on leave on some other day of the week does not exempt the employer from paying the additional compensation required in the Chapter. Time off is not currency for a statutory premium. The overtime remains payable in money.

What an Employer Can Lawfully Do

The rule is narrower than it is sometimes read to be. Several arrangements are lawful and are routinely mistaken for offsetting.

Decline to pay for hours not worked. Nothing in Article 88 requires an employer to pay for time nobody worked. If the employee left two hours early and no paid leave covers it, those two hours are simply unearned.

Adopt a compressed workweek in advance. Under DOLE Department Advisory No. 02, Series of 2004, the normal workday may be lengthened beyond eight hours — but not beyond twelve — without an overtime premium, provided the total does not exceed 48 hours a week, the scheme rests on a voluntary agreement, and it results in no diminution of existing benefits. The distinction matters: a compressed workweek redefines what the normal day is, prospectively and by agreement. Offsetting retroactively cancels hours that were already worked at a premium rate. The first restructures the baseline; the second erases an entitlement that has already vested.

Apply a genuine flexible work arrangement. DOLE Labor Advisory No. 04, Series of 2010 carries the same two conditions — voluntary agreement and no diminution of benefits. An arrangement imposed unilaterally, or one that leaves the employee worse off than before, fails both.

Let the employee use paid leave to cover the shortfall. Where the employee applies for and the employer approves the use of an existing leave credit for the unworked hours, the hours are paid from that credit. That is the leave benefit operating normally, not an offset — the employee is spending something they already own.

How Undertime Should Be Computed

Two variables decide the amount, and both should be visible on the payslip.

The correct hourly rate. The rate depends on the compensation structure and the payroll divisor the employer actually uses. A monthly-paid employee’s hourly equivalent is not derived the same way as a daily-paid employee’s, and using the wrong divisor produces a wrong deduction in every pay period, in the same direction.

Accurate time records. The hours deducted must match the daily time record, biometric log or system record. A deduction computed from memory, from a supervisor’s estimate, or from a rounding rule that always rounds against the employee is not supported.

Step	What to check
1. Establish the hourly rate	Ask which divisor payroll applied and confirm it against your contract and payslip history.
2. Count the undertime hours	Match them to the daily time record for that specific date, not to a monthly total.
3. Count the overtime hours separately	Overtime is counted per day, against the eight-hour day, and paid at its own premium.
4. Confirm nothing was netted	The two figures should appear as separate lines. A single net line is the warning sign.
5. Check the premium rate applied	At least 25 percent on an ordinary day; at least 30 percent on a rest day or holiday.

Unearned Wages Versus an Unlawful Deduction

This distinction decides which rule applies, and it is worth getting right before raising a complaint.

Hours never worked produce wages that were never earned. There is nothing to deduct because the entitlement never arose. Articles 113 to 118, which restrict deductions and prohibit the withholding of wages, govern something different: money taken out of wages the employee has already earned.

The practical consequence is that a correctly computed undertime adjustment is not an unlawful deduction. But two things can turn a payslip line into one:

An adjustment that exceeds the hours actually not worked, or that uses an inflated hourly rate.
A fixed monetary fine imposed on top of the unworked time, which is a charge against earned wages and needs its own lawful and documented basis.

Concept	What it is	Main consequence
Undertime	Fewer hours worked than scheduled on a given day.	Unworked hours are unpaid. Cannot be offset against overtime.
Tardiness	Late arrival, which is undertime occurring at the start of the day.	Same pay treatment. Any separate fine is a distinct charge needing its own basis.
Leave without pay	An approved absence that the policy does not make paid.	Unpaid but authorised — it should not read as a disciplinary matter.
AWOL	Unauthorised absence under workplace rules.	Unpaid, and may trigger a disciplinary process. Absence alone is not abandonment.

Evidence and Documentation

An undertime dispute is won or lost on records, and most of them sit with the employer. Keep your own copies as you go rather than requesting them after a disagreement has started.

The published work schedule for the period, establishing what you were actually scheduled to work.
Daily time records, biometric logs or system login records for both the undertime date and the overtime date.
The overtime authorization or approval for the day you worked beyond eight hours, including an email or chat approval where that is how your workplace does it.
Approved leave applications and schedule-change approvals, which distinguish authorised absence from undertime.
Payslips and the payroll register showing the hourly rate used, the undertime line and the overtime line as separate entries.
The employment contract, handbook or CBA provision on hours, overtime approval and any flexible work arrangement.
Written requests to payroll and their replies, which establish that you raised the issue and when.

Common Payroll Mistakes

Netting undertime against overtime in the same cut-off. The most common form, and the one Article 88 addresses directly.
Offering time off instead of overtime pay. Expressly foreclosed by the second sentence of Article 88.
Recording approved paid leave as undertime, which turns an entitlement into a deduction.
Calling an ad hoc arrangement a compressed workweek without the voluntary agreement, the 48-hour weekly cap or the non-diminution condition.
Using the wrong divisor for the hourly rate, producing a small error that repeats every period.
Rounding only against the employee — rounding undertime up and overtime down.
Adding a fixed fine on top of the unworked time without a documented lawful basis.

Practical Examples

Example 1: The classic offset

Maria leaves two hours early on Tuesday for a personal errand, with no leave credit applied. On Thursday she works ten hours to finish a deadline. Her payslip shows no overtime and no undertime — payroll cancelled them.

Assessment: This is the prohibited offset. Thursday’s two hours were worked beyond eight and are payable at the regular wage plus at least 25 percent. Tuesday’s two hours are separately unpaid. The correct payslip shows both lines, and Maria is owed the premium element that the netting erased.

Example 2: The day-off substitute

Ben works three hours of approved overtime on Monday. His supervisor tells him to take Friday afternoon off instead of claiming the pay.

Assessment: Article 88’s second sentence covers this directly. Permission to go on leave on another day does not exempt the employer from paying the additional compensation. Ben may take Friday off if that is agreed, but the Monday overtime remains payable in money.

Example 3: A genuine compressed workweek

Rina’s employer, with the written agreement of the workforce, moves to four ten-hour days totalling 40 hours a week, with no reduction in any existing benefit.

Assessment: This is not offsetting. The normal workday has been redefined prospectively within the DOLE conditions — beyond eight hours but not beyond twelve, inside a 48-hour week, voluntary, and with no diminution. Hours nine and ten on those days do not attract the overtime premium. Hours beyond the agreed ten would.

Example 4: Undertime with paid leave applied

Carlo leaves three hours early and files for three hours against his leave credits, which the employer approves.

Assessment: Those hours are paid, out of a benefit Carlo already holds. Nothing here is an offset, and the hours should not appear as undertime on the payslip.

What to Do Next

Reconstruct the two dates. Put the undertime date and the overtime date side by side with the hours actually recorded on each.
Read the payslip for netting. If overtime hours you worked do not appear, or appear reduced, and the reduction matches undertime from a different date, that is the violation.
Request an itemized computation in writing. Ask payroll to identify the hourly rate and divisor used, the undertime hours and dates deducted, the overtime hours and dates paid, and the premium rate applied to each. Keep proof that the request was sent.
Raise it internally first through your grievance mechanism where one exists, particularly under a CBA.
Escalate through SEnA if it is not corrected, by filing a Request for Assistance at a Single Entry Assistance Desk or through DOLE ARMS.
Watch the clock. Money claims generally prescribe in three years from accrual under Article 306, and each pay period accrues on its own.

Frequently Asked Questions

Can my employer offset undertime against overtime if I agreed to it in writing?

Article 88 states the prohibition without qualification, and the effect of an offset is to give up the statutory overtime premium on hours already worked. A consent clause does not convert a prohibited arrangement into a permitted one.

Is my employer required to pay me for the hours I did not work?

No. Article 88 does not require payment for unworked hours. It requires that overtime actually worked be paid separately at its premium rate, rather than cancelled against a shortfall on a different day.

Does the rule apply within the same day?

Article 88 addresses undertime on one day set against overtime on any other day. Within a single day, the question is simply how many hours were actually worked: overtime arises only for hours worked beyond eight that day, so a late start that is made up the same evening may mean no overtime was reached at all.

What if I am on a compressed workweek?

A compressed workweek adopted under DOLE Department Advisory No. 02, Series of 2004 redefines the normal workday in advance, up to twelve hours, within a 48-hour week, voluntarily and without diminishing benefits. That is lawful. It does not authorise cancelling one day’s shortfall against another day’s excess after the fact.

Can undertime be a ground for discipline?

Pay treatment and discipline are separate questions. Unworked hours are unpaid as a matter of computation. Whether repeated undertime also breaches a company rule is a disciplinary matter that follows its own process, including the notice and opportunity to be heard.

How far back can I claim?

Money claims arising from the employment relationship generally prescribe in three years from accrual under Article 306, formerly Article 291. Each affected pay period generally accrues separately.
