Night shift differential, often called NSD, is a statutory wage premium paid to covered employees who work during legally defined night hours. In the Philippines, it is one of the basic labor standards on wages and hours of work. Although the headline rule looks simple, actual payroll computation can become technical once NSD overlaps with overtime, rest days, special non-working days, and regular holidays.

This article explains the Philippine rule in full: its legal basis, who is covered, how it is computed, how it interacts with other pay premiums, common payroll errors, and practical examples.

1) What is night shift differential

Under Philippine labor law, night shift differential is an additional compensation of at least ten percent of an employee’s regular wage for each hour of work performed between 10:00 p.m. and 6:00 a.m.

The key points in that definition matter:

It is additional compensation.
It is at least 10%.
It is based on the employee’s regular wage.
It applies only to hours actually worked within the legally defined night period of 10:00 p.m. to 6:00 a.m.

The statutory basis for private-sector employees is Article 86 of the Labor Code of the Philippines.

2) Purpose of the law

The law recognizes that work performed at night carries social, physical, and biological burdens different from daytime work. NSD is meant to compensate for the inconvenience and strain of labor during nighttime hours. It is not a bonus, gratuity, or discretionary benefit. For covered employees, it is a legal entitlement.

3) Legal basis in the Philippines

For the private sector, the principal source is the Labor Code, particularly:

Article 86 – Night shift differential
Related wage-and-hours provisions on:
- hours of work
- overtime
- rest day premium
- special day and holiday pay
- coverage and exclusions from labor standards

For the public sector, there are separate rules. The framework is not the same as the Labor Code provision for private employers.

4) The basic private-sector rule

For covered private-sector employees:

For every hour actually worked between 10:00 p.m. and 6:00 a.m., the employee is entitled to at least 10% of the regular wage for that hour, in addition to the wage otherwise due for that hour.

This means NSD is an hour-based premium, not a flat amount per shift.

Example of the basic rule

If an employee’s hourly rate is ₱100, then the NSD premium for each night hour is:

₱100 × 10% = ₱10

So each hour worked during the NSD window is paid at:

₱100 + ₱10 = ₱110

If the employee works 4 hours within the NSD period, the NSD premium is:

₱10 × 4 = ₱40

5) What counts as “regular wage”

In practice, NSD is computed using the employee’s applicable hourly wage for the hour worked, subject to the wage rules for that day and hour. That is why NSD often interacts with other premiums.

The phrase “regular wage” in the context of NSD does not mean a monthly salary abstractly viewed in isolation. In payroll application, the base used is the employee’s hourly equivalent wage, adjusted where required by law because the hour falls on:

an ordinary working day
an overtime hour
a rest day
a special non-working day
a regular holiday
combinations of the above

That is why NSD is not always just a simple 10% of the bare hourly rate. When the night hour is also an overtime hour or a holiday hour, the proper statutory premium structure must be applied.

6) Who is covered

As a rule, covered private-sector employees are entitled to NSD.

This generally includes rank-and-file employees and other non-exempt employees who perform work during the statutory night period.

7) Who are usually excluded

The right to NSD arises under the Labor Code provisions on working conditions and rest periods, so the usual statutory exclusions from that labor-standards title matter.

Those generally excluded include:

a) Government employees

Government personnel are not covered by the Labor Code rule for private establishments. Their entitlement, if any, comes from separate public-sector laws and rules.

b) Managerial employees

Managerial employees are ordinarily excluded from the working-hours and related premium-pay rules.

c) Field personnel, under the legal definition

Field personnel whose actual hours of work in the field cannot be determined with reasonable certainty are generally excluded from the labor-standards provisions on hours of work and related premiums.

Not every employee who “works outside” is automatically field personnel in the legal sense. The real test is whether actual hours can be determined with reasonable certainty.

d) Family members dependent on the employer for support

Where the statutory exclusion applies.

e) Certain domestic or personal-service arrangements under older labor-standards exclusions

Domestic workers are now governed by a separate legal framework. Their rights must be analyzed under that separate statute and implementing rules, not simply assumed from the private-sector Labor Code NSD provision.

f) Workers paid by results in situations exempted by regulation

Some workers paid by results may fall under exceptions set by labor regulations.

8) Important note on domestic workers or kasambahays

Domestic workers are not best analyzed solely under the ordinary Labor Code NSD article. They are governed by a separate law on domestic work. As a practical matter, one should not automatically assume that the standard private-sector NSD rule applies to kasambahays in exactly the same way it applies to covered employees in commercial establishments.

9) Important note on government employees

The public-sector night shift differential regime is separate from the Labor Code. It uses different statutory rules and may involve different rates, coverage, and time bands. So when the question is “Philippine labor law” in the private-employment sense, the starting point is still Article 86 of the Labor Code.

10) When does NSD begin and end

For covered private-sector workers, the statutory period is:

Begins: 10:00 p.m.
Ends: 6:00 a.m.

Hours outside that period do not earn NSD.

Examples

9:00 p.m. to 5:00 a.m. shift NSD applies from 10:00 p.m. to 5:00 a.m. only
10:00 p.m. to 6:00 a.m. shift NSD applies to the entire 8-hour shift
6:00 p.m. to 2:00 a.m. shift NSD applies from 10:00 p.m. to 2:00 a.m. only
4:00 a.m. to 12:00 noon shift NSD applies from 4:00 a.m. to 6:00 a.m. only

11) NSD is based on hours actually worked

This is critical.

NSD is paid only for hours actually worked during the statutory night period. It is not paid merely because the employee is scheduled for a night shift.

That distinction matters for:

meal breaks
unpaid breaks
absences
undertime
hours not actually rendered
paid leaves
rest periods not counted as hours worked

Example

If the shift is 10:00 p.m. to 6:00 a.m. with a 1-hour unpaid meal break, and only 7 hours are compensable work hours, NSD is computed on the 7 actual work hours, not automatically on 8 hours.

12) NSD is a minimum, not a ceiling

The law requires at least 10%. Employers may grant more under:

company policy
collective bargaining agreement
employment contract
long-standing practice

If a company grants 15% or 20%, that is generally valid because the law sets a minimum floor.

13) How to compute the hourly rate

Before computing NSD, payroll must determine the employee’s correct hourly equivalent rate.

For daily-paid employees:

Hourly rate = Daily wage ÷ 8

assuming the employee’s normal workday is 8 hours.

Example

Daily wage: ₱800 Hourly rate: ₱800 ÷ 8 = ₱100

For monthly-paid employees, payroll typically converts the monthly salary to its proper daily and hourly equivalent under the employer’s payroll methodology and applicable labor rules. The exact divisor may vary depending on whether the employee is paid on a monthly-paid or daily-paid basis and the employer’s lawful salary conversion practice.

Once the lawful hourly equivalent is determined, the NSD premium is computed from that rate, with any applicable statutory premium structure for the specific hour worked.

14) Basic NSD formula on an ordinary day

For a covered employee working a night hour on an ordinary working day:

NSD premium per hour = Hourly rate × 10%

Total pay per night hour = Hourly rate × 110%

Example

Hourly rate: ₱125

NSD premium per hour: ₱125 × 10% = ₱12.50

If the employee worked 6 night hours: ₱12.50 × 6 = ₱75 NSD premium

Total pay for those 6 hours: ₱125 × 6 = ₱750 basic pay ₱75 NSD premium Total = ₱825

15) Partial overlap with the night period

A shift may only partly fall within the 10:00 p.m. to 6:00 a.m. band.

Example

Shift: 8:00 p.m. to 4:00 a.m. Hourly rate: ₱100

Hours within NSD window: 10:00 p.m. to 4:00 a.m. = 6 hours

Basic pay for 8 hours: ₱100 × 8 = ₱800

NSD premium: ₱100 × 10% × 6 = ₱60

Total pay: ₱860

16) NSD and overtime

This is where payroll errors commonly happen.

If the employee works overtime and the overtime hours fall within the NSD period, the employee may be entitled to both:

overtime pay, and
night shift differential

These are distinct labor standards. One does not cancel the other.

Ordinary-day overtime within the NSD window

Overtime on an ordinary day is paid at 125% of the hourly rate for the overtime hour. If that overtime hour is also between 10:00 p.m. and 6:00 a.m., the employee is also entitled to NSD for that hour.

A common payroll approach is:

Night overtime hourly pay on ordinary day = Hourly rate × 125% × 110%

This yields:

Hourly rate × 137.5%

Example

Hourly rate: ₱100 Employee works overtime from 10:00 p.m. to 12:00 midnight on an ordinary day.

Per overtime night hour: ₱100 × 1.25 × 1.10 = ₱137.50

For 2 hours: ₱137.50 × 2 = ₱275

This is separate from the employee’s pay for the first 8 hours.

17) NSD on a rest day

If the employee works on a rest day and the hours worked fall within 10:00 p.m. to 6:00 a.m., both the rest day premium and NSD apply.

For work on a rest day within the first 8 hours, the usual premium is 130% of the basic hourly rate. If those hours are also night hours:

Rest day night-hour pay = Hourly rate × 130% × 110%

This equals:

Hourly rate × 143%

Example

Hourly rate: ₱100 Employee works on rest day from 10:00 p.m. to 6:00 a.m.

Per hour: ₱100 × 1.30 × 1.10 = ₱143

For 8 hours: ₱143 × 8 = ₱1,144

18) NSD on overtime during a rest day

If the employee works more than 8 hours on a rest day, and those overtime hours are also night hours, the overtime premium for rest-day overtime and the NSD premium both apply.

The common formula is:

Rest day OT night-hour pay = Hourly rate × 130% × 130% × 110%

This equals:

Hourly rate × 185.9%

Example

Hourly rate: ₱100 The employee works 2 overtime hours from 12:00 midnight to 2:00 a.m. on a rest day.

Per hour: ₱100 × 1.30 × 1.30 × 1.10 = ₱185.90

For 2 hours: ₱371.80

19) NSD on a special non-working day

When an employee works on a special non-working day, the general premium for the first 8 hours is 130% of the basic rate. If the work is also done during the NSD period:

Special day night-hour pay = Hourly rate × 130% × 110%

This is also:

Hourly rate × 143%

Example

Hourly rate: ₱100 4 hours worked from 10:00 p.m. to 2:00 a.m. on a special non-working day:

Per hour: ₱143 Total: ₱572

20) NSD on overtime during a special non-working day

For overtime hours on a special non-working day that also fall within the night period:

Special day OT night-hour pay = Hourly rate × 130% × 130% × 110%

Again:

Hourly rate × 185.9%

21) NSD on a regular holiday

For work performed on a regular holiday, the basic rule for the first 8 hours is 200% of the basic wage. If those hours fall between 10:00 p.m. and 6:00 a.m., NSD is also due.

Regular holiday night-hour pay = Hourly rate × 200% × 110%

This equals:

Hourly rate × 220%

Example

Hourly rate: ₱100 Employee works from 10:00 p.m. to 6:00 a.m. on a regular holiday.

Per hour: ₱100 × 2.00 × 1.10 = ₱220

For 8 hours: ₱1,760

22) NSD on overtime during a regular holiday

If the employee renders overtime on a regular holiday and the overtime hour is within the NSD period:

Regular holiday OT night-hour pay = Hourly rate × 200% × 130% × 110%

This equals:

Hourly rate × 286%

Example

Hourly rate: ₱100 2 overtime hours worked from 12:00 midnight to 2:00 a.m. on a regular holiday:

Per hour: ₱100 × 2.00 × 1.30 × 1.10 = ₱286

For 2 hours: ₱572

23) NSD on a regular holiday that is also a rest day

When a regular holiday falls on the employee’s rest day and the employee works, the applicable premium increases further. If the worked hours are within the NSD period, NSD is added on top of that holiday-rest-day premium structure.

The precise payroll multiplier depends on the applicable holiday-premium rule in force and the classification of the day. In general, payroll should first determine the correct holiday/rest-day multiplier, then apply the NSD component to the qualifying night hours.

24) Order of computation

The safest conceptual method is this:

Determine the employee’s basic hourly rate.
Identify whether the hour is on:
- ordinary day
- rest day
- special day
- regular holiday
Determine whether the hour is:
- within the first 8 hours, or
- overtime
Apply the legally required premium for the day and hour.
If that hour falls between 10:00 p.m. and 6:00 a.m., apply the NSD premium to that qualifying hour.

Operationally, payroll systems often do this by using established hourly multipliers. That is acceptable so long as the result is legally correct and not lower than the statutory entitlement.

25) Common computation guide

Here is a practical guide for common scenarios for covered private-sector employees:

Ordinary day, night hour within first 8 hours Hourly rate × 1.10
Ordinary day, overtime night hour Hourly rate × 1.25 × 1.10 = 1.375
Rest day or special day, night hour within first 8 hours Hourly rate × 1.30 × 1.10 = 1.43
Rest day or special day, overtime night hour Hourly rate × 1.30 × 1.30 × 1.10 = 1.859
Regular holiday, night hour within first 8 hours Hourly rate × 2.00 × 1.10 = 2.20
Regular holiday, overtime night hour Hourly rate × 2.00 × 1.30 × 1.10 = 2.86

These are standard practical multipliers used in Philippine payroll computations, subject always to the employee’s actual status, the applicable day classification, and any more favorable company or CBA rule.

26) NSD does not replace overtime pay

A common misconception is that NSD already includes overtime pay. It does not.

These are separate entitlements:

Overtime pay compensates work beyond 8 hours.
NSD compensates work during the statutory night period.

If both circumstances exist, both premiums are due.

27) NSD does not automatically apply to all night-shift employees for all 8 hours

Another common mistake is to assume that a “night shift employee” automatically receives NSD for an entire shift. The law only grants NSD for actual hours worked between 10:00 p.m. and 6:00 a.m.

So:

A shift from 6:00 p.m. to 2:00 a.m. earns NSD only for 4 hours
A shift from 9:00 p.m. to 5:00 a.m. earns NSD only for 7 hours
A shift from 11:00 p.m. to 7:00 a.m. earns NSD only for 7 hours

28) Meal breaks and NSD

If the meal break is unpaid and not counted as hours worked, it is ordinarily excluded from NSD computation.

Example

Shift: 10:00 p.m. to 6:00 a.m. Unpaid meal break: 2:00 a.m. to 3:00 a.m.

NSD hours actually worked: 7 hours

Not 8.

If, however, the meal period is compensable under the law because the employee remains on duty or the circumstances make the time compensable, that period may also be included.

29) Paid leave days do not ordinarily generate NSD

If an employee is on:

vacation leave
sick leave
maternity or other leave
paid day off

there is generally no NSD unless a specific contract, CBA, or policy says otherwise, because NSD is tied to actual night work rendered, not mere paid status.

30) NSD and undertime

If the employee leaves early or fails to complete all scheduled hours, NSD is computed only on the qualifying night hours actually rendered.

31) NSD and compressed workweek or alternative schedules

Alternative work arrangements do not remove statutory NSD if the employee remains covered by labor standards and actually works between 10:00 p.m. and 6:00 a.m.

A compressed workweek changes the schedule structure; it does not erase the legal premium for qualifying night hours.

32) NSD and flexible work arrangements

Likewise, flexible or shifting schedules do not defeat NSD. The test remains the same:

Is the employee covered by the labor standard?
Did the employee actually work between 10:00 p.m. and 6:00 a.m.?

If yes, NSD is generally due.

33) NSD and work-from-home

Remote work does not, by itself, remove NSD entitlement. If a covered employee working from home actually renders work during the statutory night period, the employee may still be entitled to NSD.

The legal issue is not the worksite but the status of the employee and the hours actually worked.

The practical challenge is proof and timekeeping.

34) Time records are crucial

Because NSD is an hour-based statutory premium, employers should maintain accurate records of:

clock-in and clock-out times
break periods
overtime authorizations
day classification
shift assignments
payroll computations

Poor timekeeping is one of the most common sources of wage claims.

35) Burden in labor disputes

In wage-and-hours cases, employers are expected to keep payroll and time records. When records are incomplete or unreliable, disputes tend to be resolved against the employer more easily. For that reason, a clean audit trail is essential.

36) Can NSD be waived

As a rule, labor standards rights are not lightly waived, especially by private agreement that gives less than the statutory minimum.

An employee’s supposed waiver of a lawful NSD entitlement is generally suspect if it results in payment below the legal minimum.

A company policy stating “night shift premium deemed included in salary” must still satisfy the law. If the arrangement leads to underpayment of the statutory minimum, it may be invalid or at least insufficient.

37) Can NSD be integrated into salary

Employers sometimes structure compensation so that wage premiums are allegedly “built in” to a higher package. That can be valid only if the package clearly and demonstrably satisfies all statutory minimums and does not conceal underpayment.

The safer compliance practice is to show NSD transparently in payroll records.

38) NSD and CBA or company policy

A CBA, employment contract, or company policy may grant:

a higher NSD rate
a broader covered time band
more favorable treatment of breaks
additional night-shift allowances separate from NSD

These benefits are valid so long as they are not less favorable than law.

It is also important to distinguish NSD from a night shift allowance. An allowance is not necessarily the same as the statutory premium. An employer cannot avoid the legal NSD by relabeling it as something else unless the employee still receives at least the full statutory entitlement.

39) NSD versus night shift allowance

They are not automatically identical.

NSD is a statutory pay premium.
Night shift allowance may be a contractual or company-granted benefit.

An employer may grant both. But if the employer wants an allowance to be treated as compliance with NSD, the figures and payroll treatment must still meet the legal floor.

40) NSD and holiday pay for unworked holidays

If a regular holiday is unworked, the employee’s right is analyzed under holiday-pay rules. NSD generally concerns actual hours worked at night, so it usually arises only when work is actually performed during the statutory night band.

41) NSD and piece-rate or output-based workers

For workers paid by results, the answer depends on whether they fall within statutory or regulatory exclusions. One cannot assume automatic entitlement or automatic exclusion. The actual regulatory classification and the nature of the work arrangement matter.

42) NSD and supervisors

Being called a “supervisor” does not automatically remove NSD entitlement. The legal question is whether the employee is truly managerial within the statutory definition, or otherwise exempt. Job title alone is not controlling.

43) NSD and officers-in-charge

Likewise, labels such as “team leader,” “supervisor,” or “officer-in-charge” do not automatically exempt an employee from labor standards. Actual duties, power to lay down management policies, and the real nature of the role matter.

44) NSD and field employees

Employers often overuse the term “field employee.” Not every employee who reports to clients, travels, or works outside the office is legally exempt. If hours can still be monitored or determined with reasonable certainty, the exemption may not apply.

This is a common area of litigation.

45) Sample full-shift computations

Example 1: Ordinary day, no overtime

Daily wage: ₱800 Hourly rate: ₱100

Shift: 9:00 p.m. to 5:00 a.m. Hours worked: 8 Night hours: 10:00 p.m. to 5:00 a.m. = 7 hours

Basic pay: ₱100 × 8 = ₱800

NSD premium: ₱100 × 10% × 7 = ₱70

Total pay: ₱870

Example 2: Ordinary day with 2 hours overtime, both within NSD period

Daily wage: ₱800 Hourly rate: ₱100

Regular shift: 2:00 p.m. to 10:00 p.m. Overtime: 10:00 p.m. to 12:00 midnight

Pay for first 8 hours: ₱800

Overtime night pay for 2 hours: ₱100 × 1.25 × 1.10 × 2 = ₱275

Total pay: ₱1,075

Example 3: Rest day night shift

Daily wage: ₱800 Hourly rate: ₱100

Shift on rest day: 10:00 p.m. to 6:00 a.m.

Per hour: ₱100 × 1.30 × 1.10 = ₱143

For 8 hours: ₱1,144

Example 4: Regular holiday night shift with 1 overtime hour

Daily wage: ₱800 Hourly rate: ₱100

Hours 1 to 8: 10:00 p.m. to 6:00 a.m. Overtime: 6:00 a.m. to 7:00 a.m.

Night holiday pay for 8 hours: ₱100 × 2.00 × 1.10 × 8 = ₱1,760

Overtime holiday pay for 1 extra hour at 6:00 a.m.: Since 6:00 a.m. is outside the NSD period, only holiday OT applies: ₱100 × 2.00 × 1.30 = ₱260

Total pay: ₱2,020

46) Boundary-hour questions

Is 10:00 p.m. included

Yes. Work from 10:00 p.m. onward is within the NSD period.

Is 6:00 a.m. included

The safer practical reading is that the NSD period runs up to 6:00 a.m. Payroll should count the portion of work performed before the end of the night period. In actual payroll systems, shifts are commonly broken into hourly or minute-based segments. The important point is that work beyond the NSD period is not included.

47) Minute-based computation

Although examples often use whole hours, payroll can compute NSD proportionally by minutes.

Example

Hourly rate: ₱120 Employee works from 9:30 p.m. to 12:30 a.m.

Night period worked: 10:00 p.m. to 12:30 a.m. = 2.5 hours

NSD premium: ₱120 × 10% × 2.5 = ₱30

48) Payroll best practice: compute by actual time segment

The most accurate payroll method is to compute by actual time segment:

ordinary day hours
overtime hours
holiday hours
rest day hours
qualifying night hours

This reduces error, especially where a shift crosses calendar days or changes legal classifications at midnight.

49) Does NSD apply to all industries

For covered employees in private establishments, yes in principle. The more important issue is not the industry name but whether the employee is covered or exempt under labor standards.

50) Interaction with wage orders

Regional wage orders fix minimum wages. NSD is computed on the employee’s lawful wage rate. It does not replace compliance with minimum wage. If the employee is already underpaid on base wage, adding a night premium does not cure the underlying minimum-wage violation.

51) Underpayment claims and prescriptive issues

If an employer fails to pay NSD, the claim may be pursued as a money claim under Philippine labor law, subject to the applicable prescription rules for money claims. Employees commonly seek recovery through DOLE mechanisms or labor adjudication, depending on the nature and amount of the claim and the relief sought.

52) Employer liability for wrong classification

A frequent source of NSD disputes is the employer’s claim that the employee is:

managerial
field personnel
exempt due to rank
covered by “fixed salary all-in” arrangement

If the classification is legally wrong, the employer may be liable for unpaid NSD, and possibly related differentials.

53) NSD and evidentiary documents employees should keep

From a claims perspective, employees usually strengthen an NSD claim by keeping:

payslips
schedules
DTRs or time records
screenshots of log-in/log-out records
messages assigning night work
holiday and rest day rosters

54) NSD in BPO, hospitals, manufacturing, retail, logistics

These industries commonly involve night work, but the legal test remains the same. BPO employees, nurses in private hospitals, factory workers, security-related staff in private firms, warehouse workers, and similar personnel may be entitled to NSD if they are covered employees and actually work during the statutory night period.

55) Health personnel and special scheduling rules

Health personnel may be subject to special rules on hours of work in certain establishments, but that does not automatically remove NSD. The premium still depends on the specific legal framework applicable to the employee and the actual night work rendered.

56) NSD and “graveyard shift” terminology

“Graveyard shift” is a colloquial term, not a legal one. A graveyard shift often falls largely or entirely within the NSD period, but the legal computation still depends on actual hours worked from 10:00 p.m. to 6:00 a.m.

57) Employer cannot average out non-night hours against night hours

An employer should not reduce NSD by saying the employee worked some daytime hours in the same cut-off period. NSD is computed hour by hour on qualifying night work, not averaged away over the pay period.

58) NSD should appear clearly in payroll

Good payroll practice is to show NSD as a separate line item or as part of a clearly auditable premium-pay breakdown. This helps prove compliance and prevents disputes.

59) Audit checklist for employers

An employer checking compliance should ask:

Are our employees properly classified as covered or exempt?
Do time records capture actual hours worked, including breaks?
Do we isolate the 10:00 p.m. to 6:00 a.m. segment correctly?
Do we apply NSD on top of overtime, rest day, special day, and holiday premiums where legally required?
Do payslips show the premium transparently?
Are company policies at least as favorable as law?

60) Quick-reference formulas

Assume HR = hourly rate.

Ordinary day

Night hour within 8 hours: HR × 1.10
Overtime night hour: HR × 1.25 × 1.10

Rest day or special day

Night hour within 8 hours: HR × 1.30 × 1.10
Overtime night hour: HR × 1.30 × 1.30 × 1.10

Regular holiday

Night hour within 8 hours: HR × 2.00 × 1.10
Overtime night hour: HR × 2.00 × 1.30 × 1.10

61) Bottom line

Under Philippine private-sector labor law, night shift differential is a mandatory minimum premium of at least 10% for every hour actually worked between 10:00 p.m. and 6:00 a.m. by a covered employee. It is not optional, not a mere allowance, and not absorbed automatically by labels or vague salary wording. It must be correctly computed per qualifying hour, and where the same hour is also overtime, a rest day hour, a special-day hour, or a holiday hour, the corresponding statutory premium structure must also be applied.

In real payroll practice, the hardest issues are usually not the 10% rate itself but:

coverage versus exemption
accurate time records
overlap with overtime and premium days
lawful handling of meal breaks
proper transparency in payroll computation

A correct analysis always starts with four questions:

Is the employee covered by labor standards?
Was work actually performed between 10:00 p.m. and 6:00 a.m.?
Was the hour ordinary, overtime, rest day, special day, or holiday work?
Is there any more favorable contract, CBA, or company policy?

That framework captures almost every NSD problem under Philippine labor law.
