Philippine Labor Law Glossary
Definition: Night shift work in Philippine labor law is work performed between ten o’clock in the evening and six o’clock in the morning. Every covered employee must be paid a night shift differential of not less than ten percent of the regular wage for each hour worked within that window. The entitlement cannot be waived.
Sa Filipino · Filipino Explanation
Ano ang Night Shift?
Sa batas, ang night shift ay ang trabahong ginagawa sa pagitan ng alas-10 ng gabi hanggang alas-6 ng umaga. Para sa bawat oras sa loob ng oras na ito, may dagdag na hindi bababa sa 10% ng sahod — ito ang tinatawag na night shift differential.
Tatlong mahahalagang punto. Una: “hindi bababa sa” ang sabi ng batas — kaya ang 10% ay pinakamababa, hindi takdang halaga; kung mas mataas ang nasa CBA o patakaran, iyon ang susundin. Pangalawa: hindi ito puwedeng iwaksi o i-waive, kahit pumayag ka pa — ayon sa Korte Suprema, nakabatay ito sa public policy. Pangatlo: magkapatong ang NSD at overtime — hiwalay silang benepisyo, hindi pamalit sa isa’t isa.
The Statutory Rule
Article 86 of the Labor Code is short enough to quote in full: “Every employee shall be paid a night shift differential of not less than ten percent (10%) of his regular wage for each hour of work performed between ten o’clock in the evening and six o’clock in the morning.”
Three things follow from the wording. The differential is computed per hour, not per shift, so an employee who works only from 10 p.m. to midnight earns it on two hours. The window is fixed by statute at 10 p.m. to 6 a.m., regardless of what a company calls its shifts. And the phrase “not less than” makes 10% a floor: a collective bargaining agreement or company policy granting 15% or 20% is enforceable at that higher rate.
Who Is Excluded
The exclusions from the night shift differential are set out in the Omnibus Rules Implementing the Labor Code, Book III, Rule II, Section 1 — not in Article 82, which is frequently but incorrectly cited for this purpose. The two lists differ materially, and the Rule is the operative one here.
| Excluded category |
|---|
| Employees of the government and any of its political subdivisions, including government-owned and controlled corporations |
| Those of retail and service establishments regularly employing not more than five (5) workers |
| Domestic helpers and persons in the personal service of another |
| Managerial employees as defined in the Rules |
| Field personnel and other employees whose time and performance is unsupervised by the employer, including those engaged on task or contract basis, purely commission basis, or paid a fixed amount for performing work irrespective of the time consumed |
Note in particular the five-worker retail and service exclusion, which appears in the Rule but not in Article 82. Getting this backwards is one of the more common errors in Philippine human resources material.
The Entitlement Cannot Be Waived
An employment contract clause saying the employee waives the night differential, or a salary package described as “all-inclusive” of it, does not extinguish the entitlement.
In Mercury Drug Co., Inc. v. Dayao, decided 30 September 1982, the Supreme Court held: “The ‘waiver rule’ is not applicable… Additional compensation for nighttime work is founded on public policy, hence the same cannot be waived. (Article 6, Civil Code).”
What an agreement can do is regulate mechanics. In Lepanto Consolidated Mining Company v. Lepanto Local Staff Union, decided 20 August 2008, a collective bargaining agreement governed the sequence in which premiums were computed — but the underlying entitlement itself was not extinguishable by contract.
Night Differential Stacks With Other Premiums
The night shift differential is not an alternative to overtime, rest-day or holiday premiums; it applies on top of them. The Department of Labor and Employment publishes the combined multipliers, and their multiplicative structure is itself the proof that the benefits compound rather than substitute:
| Situation | Multiplier on the hourly rate |
|---|---|
| Ordinary day, night hours | 110% |
| Ordinary day, night hours, overtime | 137.5% |
| Rest day, night hours | 143% |
| Special day, night hours | 143% |
| Regular holiday, night hours | 220% |
| Regular holiday, night hours, overtime | 286% |
Republic Act No. 10151 Changed the Framework, Not the Rate
Republic Act No. 10151, approved 21 June 2011, repealed Articles 130 and 131 of the Labor Code — the old prohibition on nightwork by women — and inserted a new Chapter V on employment of night workers, comprising Articles 154 to 161: coverage, health assessment, mandatory facilities, transfer, women night workers, compensation, social services and night work schedules.
Two points matter for anyone computing pay. First, the “night period” defined in that Chapter is different from Article 86’s: it is “not less than seven (7) consecutive hours, including the interval from midnight to five o’clock in the morning.” That definition governs the health-and-safety obligations in Chapter V, not the differential. Second, Article 159 states a principle — that measures shall recognise the exceptional nature of night work — rather than a rate. Republic Act No. 10151 did not change the 10%.
Government Employees Are on a Different Regime
Republic Act No. 11701, approved 13 April 2022, grants a night shift differential to government employees at a rate “not exceeding twenty percent (20%) of the hourly basic rate,” for work performed “between the hours of 6:00 in the evening and 6:00 in the morning,” covering positions of Division Chief and below.
Both the window and the rate differ from Article 86. Do not blend the two: private-sector computation runs on 10 p.m. to 6 a.m. at not less than 10%; the government scheme runs on 6 p.m. to 6 a.m. at not more than 20%.

Practical Examples
Partial night hours: An employee on a 6 p.m. to 2 a.m. shift works four hours inside the statutory window (10 p.m. to 2 a.m.). The differential is computed on those four hours only.
Ordinary night hours: Hourly rate ₱100. Each night hour is paid ₱100 × 110% = ₱110.
Overtime at night: Same rate. An overtime hour falling within the night window is paid ₱100 × 137.5% = ₱137.50 — the overtime and night premiums compound.
Common Misunderstandings
Misunderstanding: The exclusions from the night shift differential are the ones listed in Article 82.
Correct approach: The operative list is Omnibus Rules, Book III, Rule II, Section 1. It adds retail and service establishments with not more than five workers and differs from Article 82 in several respects.
Misunderstanding: An employee who signs a contract accepting a package “inclusive of night differential” has validly waived it.
Correct approach: Mercury Drug v. Dayao holds that the benefit rests on public policy and cannot be waived. What the employer must be able to show is actual payment, not consent to non-payment.
Common Questions
Is night shift differential the same as overtime pay?
No. Overtime compensates hours worked beyond eight in a day; the night differential compensates hours worked within the 10 p.m. to 6 a.m. window, whether or not they are overtime hours. An hour can attract both.
Do BPO and call centre employees get night differential?
Yes, if they fall outside the five excluded categories. Working a night-based shift pattern does not remove the entitlement; the multiplier applies to every hour inside the statutory window.
Are managers entitled to night differential?
Managerial employees as defined in the Rules are among the excluded categories. The label on a job title is not decisive — what matters is whether the employee meets the definition in the implementing rules.
