I. Introduction

A three-day workweek is an alternative work arrangement where an employee is required to report for work only three days per week, instead of the more common five-day or six-day schedule. In the Philippine context, it may arise in part-time employment, compressed work arrangements, flexible work schedules, project-based work, consultancy-like employment arrangements, or reduced operations.

Computing annual working days for a three-day workweek is important because it affects payroll, leave credits, holiday pay, service incentive leave, 13th month pay, daily rate conversion, absences, undertime, probationary period tracking, and benefits administration.

The basic idea is simple: determine how many days in a year the employee is actually scheduled to work. But in legal and payroll practice, the computation must also consider Philippine labor rules on workdays, rest days, holidays, leave benefits, wage orders, company policy, employment contracts, and whether the employee is paid daily, monthly, or per output.

II. Meaning of “Annual Working Days”

“Annual working days” refers to the number of days in a year when an employee is expected to render work under the agreed schedule.

For a three-day workweek, this usually means:

3 workdays per week × 52 weeks = 156 scheduled workdays per year

This is the starting point, but not always the final number for payroll or legal purposes.

The annual working days may be affected by:

whether the employee has fixed workdays;
whether holidays fall on scheduled workdays;
whether the employee is monthly-paid or daily-paid;
whether paid holidays are included in compensation;
whether leave days are paid;
whether the employer grants additional company holidays;
whether the year is a leap year;
whether the employment started or ended mid-year;
whether the schedule changes during the year;
whether the employee is covered by a compressed workweek or ordinary part-time schedule.

III. Basic Formula

The simplest formula is:

[ \text{Annual Working Days} = \text{Workdays per Week} \times 52 ]

For a three-day workweek:

[ 3 \times 52 = 156 ]

So, as a general rule:

A regular three-day workweek has approximately 156 scheduled working days per year.

This assumes the employee works three days every week for the entire year.

IV. Why 52 Weeks Is Used

A calendar year has 365 days, or 366 days in a leap year.

Since there are 7 days in a week:

[ 365 \div 7 = 52 \text{ weeks and 1 day} ]

In a leap year:

[ 366 \div 7 = 52 \text{ weeks and 2 days} ]

For rough annualization, employers commonly use 52 weeks. But for exact payroll, the actual calendar must be checked because the extra one or two days may fall on one of the employee’s scheduled workdays.

Therefore:

ordinary year approximation: 156 days;
exact ordinary year count: may be 156 or 157, depending on the schedule;
exact leap year count: may be 156, 157, or 158, depending on the schedule.

V. Exact Calendar Method

For strict computation, do not simply multiply by 52. Count the actual number of scheduled workdays in the specific calendar year.

Example:

An employee works every Monday, Wednesday, and Friday.

To compute annual working days:

identify the year;
list all Mondays, Wednesdays, and Fridays in that year;
count them;
exclude or separately treat non-working days depending on the purpose of the computation.

Because a year has 52 full weeks plus 1 extra day, each weekday normally occurs at least 52 times. The weekday on January 1, or the extra day created by the calendar, may occur 53 times.

In a leap year, two weekdays occur 53 times.

Thus, a three-day schedule may have more than 156 scheduled days if one or two of the selected workdays occur 53 times in that year.

VI. Approximate Method vs. Exact Method

A. Approximate Method

Use:

[ 3 \times 52 = 156 ]

This is useful for:

estimating annual workload;
preparing employment offers;
budgeting;
computing approximate equivalent monthly salary;
comparing schedules;
planning manpower.

B. Exact Method

Count actual scheduled days in the year.

This is better for:

payroll implementation;
leave charging;
holiday pay;
pro-rated salary;
final pay;
employment periods shorter than one year;
compliance audits;
disputes over absences or benefits.

The exact method is more legally defensible because it uses the actual calendar and actual schedule.

VII. Effect of Leap Year

A leap year has 366 days. This means there are 52 full weeks plus 2 extra days.

For a three-day workweek, the annual count may increase if the two extra weekdays are part of the employee’s schedule.

Example:

If a leap year has 53 Mondays and 53 Tuesdays, and the employee works Monday, Wednesday, and Friday, the employee may have one additional scheduled workday because Monday occurs 53 times.

If the two extra weekdays are both part of the schedule, the employee may have two additional scheduled workdays.

Therefore, in a leap year, a three-day workweek may result in:

156 days, if neither extra weekday is a scheduled workday;
157 days, if one extra weekday is a scheduled workday;
158 days, if both extra weekdays are scheduled workdays.

VIII. Fixed Schedule vs. Rotating Schedule

A. Fixed Three-Day Schedule

A fixed schedule means the employee works the same three days each week, such as Monday-Wednesday-Friday.

This is easier to compute because the employer can count those exact weekdays in the calendar year.

Example:

Monday, Wednesday, Friday every week;
Tuesday, Thursday, Saturday every week;
Wednesday, Friday, Sunday every week.

B. Rotating Three-Day Schedule

A rotating schedule means the employee works three days per week, but the days change.

Example:

Week 1: Monday, Tuesday, Wednesday;
Week 2: Thursday, Friday, Saturday;
Week 3: Sunday, Monday, Tuesday.

For rotating schedules, annual working days should be based on the actual roster, not merely the theoretical schedule.

The employer should maintain written schedules because disputes may arise over holidays, rest days, premium pay, and absences.

IX. Philippine Labor Law Context

Philippine labor law does not prohibit a three-day workweek by itself. What matters is whether the arrangement complies with minimum labor standards.

Relevant labor concepts include:

normal hours of work;
rest days;
overtime;
night shift differential;
holiday pay;
premium pay;
service incentive leave;
minimum wage;
wage orders;
social benefits;
13th month pay;
written employment terms.

A three-day workweek may be lawful if the employee receives at least the applicable minimum wage and statutory benefits, and if hours and compensation comply with law.

X. Three-Day Workweek and Daily Hours

A three-day workweek does not automatically mean fewer total weekly hours. There are two common models.

A. Reduced Workweek

The employee works fewer days and fewer total hours.

Example:

3 days per week;
8 hours per day;
total of 24 hours per week.

This is common for part-time or reduced-load employees.

B. Compressed Workweek

The employee works fewer days but longer daily hours.

Example:

3 days per week;
12 hours per day;
total of 36 hours per week.

A compressed workweek must be structured carefully. Philippine labor standards generally recognize the eight-hour workday as the ordinary baseline. If daily hours exceed eight, the arrangement should be supported by a valid compressed workweek policy or agreement consistent with labor advisories and rules. Otherwise, hours beyond eight may raise overtime issues.

XI. Annual Working Days vs. Annual Working Hours

Annual working days and annual working hours are different.

For a three-day workweek, annual working days may be 156, but annual working hours depend on hours per day.

Example 1: 8 Hours Per Day

[ 156 \times 8 = 1,248 \text{ working hours per year} ]

Example 2: 10 Hours Per Day

[ 156 \times 10 = 1,560 \text{ working hours per year} ]

Example 3: 12 Hours Per Day

[ 156 \times 12 = 1,872 \text{ working hours per year} ]

Thus, a three-day workweek may have fewer, similar, or near-full annual hours depending on the daily schedule.

XII. Computation Using Calendar Days

Another way to estimate is:

[ 365 \times \frac{3}{7} = 156.43 ]

This shows why the usual annual estimate is about 156 days.

For a leap year:

[ 366 \times \frac{3}{7} = 156.86 ]

This shows why the exact count can sometimes be 157 or 158, depending on which weekdays are scheduled.

XIII. Effect of Regular Holidays and Special Non-Working Days

Philippine employment law recognizes regular holidays and special non-working days. These affect pay, but they do not always reduce the count of scheduled workdays in the same way for every employee.

The treatment depends on the purpose of the computation.

A. For Scheduling Purposes

A holiday that falls on the employee’s scheduled workday is still a scheduled workday, but the employee may not be required to work depending on company policy and the nature of operations.

Example:

An employee works Monday-Wednesday-Friday. If a regular holiday falls on a Monday, that Monday is part of the employee’s schedule.

B. For Actual Days Worked

If the employee does not work on that holiday, then it is not an actual day worked.

C. For Paid Days

If the employee is entitled to holiday pay, the holiday may be a paid day even if no work is performed.

Thus, employers should distinguish:

scheduled working days;
actual days worked;
paid days;
days counted for leave or benefits.

These are not always the same.

XIV. Holiday Pay for Three-Day Workweek Employees

Holiday pay depends on the employee’s status, wage structure, and whether the holiday falls on a scheduled workday.

For covered employees, if a regular holiday falls on a scheduled workday, the employee may be entitled to holiday pay even if no work is performed, subject to applicable rules.

If the employee works on a regular holiday, the applicable holiday work rate may apply.

If the holiday falls on a day when the employee is not scheduled to work, the treatment may depend on whether the employee is monthly-paid, daily-paid, part-time, or covered by specific company policy.

Important point:

A three-day schedule does not automatically remove statutory holiday rights.

However, the actual holiday pay computation must be aligned with the employee’s pay basis and coverage.

XV. Special Non-Working Days

Special non-working days are treated differently from regular holidays.

Usually, the “no work, no pay” principle applies unless there is a favorable company policy, contract, or collective bargaining agreement.

If an employee works on a special non-working day, premium pay rules may apply, depending on coverage.

For a three-day workweek employee, the key question is whether the special day falls on a scheduled workday and whether the employee actually worked.

XVI. Rest Days

Employees are generally entitled to a rest period after six consecutive normal workdays. A three-day workweek typically has more than enough non-working days, but the employer should still identify the employee’s regular rest days.

This matters because work performed on a designated rest day may trigger premium pay.

For a three-day workweek, the four non-working days are not automatically all “rest days” in the same payroll sense unless designated as such. Employers should define which days are rest days, off-days, or non-scheduled days to avoid confusion.

XVII. Minimum Wage Compliance

A three-day workweek employee must still be paid at least the applicable minimum wage for covered hours and days of work.

For daily-paid employees, the daily wage should not fall below the applicable minimum daily wage for the region and sector, unless a lawful exception applies.

For part-time employees, wage may be proportionate to hours worked, but the hourly equivalent must comply with minimum wage rules.

Example:

If the applicable minimum daily wage assumes an eight-hour day, the hourly equivalent is generally derived by dividing the daily minimum wage by eight. A four-hour part-time worker should generally receive at least the proportionate hourly minimum.

XVIII. Monthly Salary Under a Three-Day Workweek

If an employee is monthly-paid under a three-day workweek, the employer should define whether the monthly salary covers:

only actual scheduled workdays;
paid holidays falling on scheduled days;
all calendar months regardless of number of scheduled days;
leave benefits;
rest days;
premiums and overtime separately.

Monthly salary may be lawful, but the employer must ensure that the monthly equivalent does not result in payment below statutory minimums.

XIX. Daily Rate Conversion

If an employee receives a monthly salary but works only three days per week, daily rate conversion may be necessary for:

absences;
unpaid leave;
holiday pay;
final pay;
salary deductions;
overtime;
premium pay;
13th month pay analysis.

A common formula is:

[ \text{Daily Rate} = \frac{\text{Annual Salary}}{\text{Annual Paid Days or Working Days}} ]

But the denominator must be chosen carefully.

Possible denominators:

156 scheduled working days;
exact annual scheduled working days;
scheduled working days plus paid holidays;
company-defined factor;
contractually agreed equivalent, if lawful.

The wrong denominator can lead to underpayment or over-deduction.

XX. Monthly Equivalent Factor

To convert a three-day weekly schedule into an average monthly number of workdays:

[ 3 \times 52 \div 12 = 13 ]

Thus, a three-day workweek averages approximately 13 working days per month.

This is useful for budgeting and salary conversion.

Example:

If the agreed daily rate is ₱1,000:

[ ₱1,000 \times 13 = ₱13,000 ]

So the approximate monthly equivalent is ₱13,000.

But exact monthly pay may vary depending on the number of scheduled workdays in each month unless the employee is paid a fixed monthly salary.

XXI. Exact Monthly Counting

A fixed Monday-Wednesday-Friday schedule will not always have exactly 13 workdays per month.

Some months may have:

12 scheduled workdays;
13 scheduled workdays;
14 scheduled workdays;
sometimes more depending on calendar alignment.

Daily-paid employees are usually paid based on actual scheduled days worked or paid days in that payroll period.

Monthly-paid employees usually receive the same monthly salary unless there are absences, unpaid leave, or other adjustments.

XXII. Annual Working Days for Mid-Year Employment

If the employee starts or ends employment mid-year, use a pro-rated computation.

Formula:

[ \text{Working Days During Employment} = \text{Number of Scheduled Workdays from Start Date to End Date} ]

For accuracy, count the actual scheduled workdays during the period.

Example:

An employee works Monday-Wednesday-Friday and starts on July 1. Count all Mondays, Wednesdays, and Fridays from July 1 to December 31.

Do not simply divide 156 by 2 unless an approximation is acceptable. The exact number depends on the calendar.

XXIII. Service Incentive Leave

Under Philippine labor law, covered employees who have rendered at least one year of service are generally entitled to five days of service incentive leave with pay, unless exempt or already receiving equivalent or better benefits.

For a three-day workweek employee, the main issues are:

whether the employee is covered;
whether the employee has completed one year of service;
how to value one leave day;
whether company policy grants more favorable leave;
whether leave is pro-rated.

A “day” of service incentive leave is usually tied to the employee’s regular workday. If the employee’s regular day is 8 hours, one leave day is generally 8 paid hours. If the employee’s regular workday is longer under a valid arrangement, the valuation should be carefully defined.

XXIV. Leave Accrual in a Three-Day Workweek

Employers may grant leave on a statutory, contractual, or company policy basis.

Possible approaches:

A. Same Number of Leave Days

The employee receives the same five SIL days after one year, even if working only three days per week.

This is straightforward and may be more favorable.

B. Pro-Rated Leave

For company-granted leaves above statutory minimums, the employer may provide proportionate accrual based on work schedule, if lawful and clearly stated.

Example:

A full-time five-day employee receives 15 vacation leaves annually. A three-day employee may receive:

[ 15 \times \frac{3}{5} = 9 ]

This depends on policy and must not violate statutory minimums.

C. Hours-Based Leave

Leave may be expressed in hours to avoid distortion.

Example:

A three-day employee working 8 hours per day and granted 5 leave days has:

[ 5 \times 8 = 40 \text{ leave hours} ]

Hours-based leave is often clearer for alternative schedules.

XXV. 13th Month Pay

Rank-and-file employees are generally entitled to 13th month pay if they meet the requirements.

For a three-day workweek employee, 13th month pay is usually based on the employee’s basic salary actually earned during the calendar year.

Basic formula:

[ \text{13th Month Pay} = \frac{\text{Total Basic Salary Earned During the Year}}{12} ]

Thus, if the employee works fewer days and earns proportionately lower basic salary, the 13th month pay will also be proportionate.

Example:

If the employee earns ₱18,000 monthly basic salary for the entire year:

[ ₱18,000 \times 12 \div 12 = ₱18,000 ]

If the employee is daily-paid at ₱1,000 per day and works 156 days:

[ ₱1,000 \times 156 = ₱156,000 ]

[ ₱156,000 \div 12 = ₱13,000 ]

So the 13th month pay is ₱13,000, excluding items not considered basic salary.

XXVI. Absences and Deductions

For three-day workweek employees, absence deductions should be based on the employee’s actual pay structure.

A. Daily-Paid Employee

If the employee is daily-paid and absent on a scheduled workday, the employee generally receives no pay for that day, unless covered by paid leave or holiday rules.

B. Monthly-Paid Employee

If the employee is monthly-paid, the employer needs a daily rate to compute the deduction.

Possible formula:

[ \text{Absence Deduction} = \text{Daily Rate} \times \text{Number of Unpaid Absences} ]

The daily rate should be derived from the agreed salary structure and lawful company policy.

XXVII. Overtime

If the employee works beyond the legally recognized normal hours, overtime issues may arise.

For a three-day workweek employee working 8 hours per day, hours beyond 8 in a day may generally be overtime unless a valid arrangement applies.

For compressed workweeks, work beyond 8 hours may be treated differently only if the arrangement complies with applicable rules and does not reduce statutory benefits.

Work beyond scheduled days may also require analysis as overtime, rest day work, or additional regular work depending on the arrangement.

XXVIII. Night Shift Differential

If a three-day workweek employee works during the statutory night shift period, night shift differential may apply if the employee is covered.

The three-day schedule does not remove night shift rights.

Example:

An employee works Monday, Wednesday, Friday from 8:00 p.m. to 5:00 a.m. The night work portion may be subject to night shift differential.

XXIX. Premium Pay for Rest Day and Holiday Work

If the employee works on a regular holiday, special non-working day, or rest day, premium rules may apply depending on labor law coverage.

The schedule should clearly identify:

regular workdays;
rest days;
non-scheduled days;
holidays;
special days;
overtime treatment.

This avoids disputes over whether an additional day worked is ordinary work, rest day work, or overtime.

XXX. Probationary Employment and Six-Month Period

A three-day workweek does not necessarily mean that the probationary period is counted only by working days. Probationary employment is commonly measured by calendar months, unless the contract or nature of employment lawfully provides otherwise.

Thus, a six-month probationary period is not automatically extended simply because the employee works three days per week.

However, for project-based, seasonal, or training-sensitive positions, the employer should clearly define evaluation periods, performance standards, and schedule expectations.

XXXI. Social Security, PhilHealth, and Pag-IBIG

Employees under a three-day workweek may still be covered by statutory social benefit systems if they are employees.

Contributions are generally based on compensation and applicable contribution tables or rules.

The reduced work schedule does not automatically remove coverage. Employers should properly register employees and remit contributions based on actual compensation.

XXXII. Employment Status

A three-day workweek does not by itself determine whether a worker is regular, probationary, project-based, seasonal, casual, or part-time.

Employment status depends on the nature of the work, the employer’s business, the employment agreement, and the legal standards on regularization.

A person may be a regular employee even if working only three days per week, if the work is necessary or desirable to the employer’s business and the legal conditions for regular employment are met.

XXXIII. Part-Time Employees

A three-day workweek is often associated with part-time employment. Philippine labor law allows part-time work, but part-time employees are still entitled to labor standards proportionate to their work and pay, unless lawfully exempt.

Important principles:

part-time status does not mean no benefits;
minimum wage still applies proportionately;
statutory benefits may still apply;
written terms are important;
hours and days should be documented;
leave and holiday rules should be clearly administered.

XXXIV. Compressed Workweek

A compressed workweek allows normal weekly hours to be compressed into fewer days. For example, instead of working 8 hours for 5 days, an employee may work longer hours over fewer days.

For a three-day compressed workweek, the employer should ensure:

the arrangement is voluntary or properly adopted;
it does not reduce existing benefits;
it does not violate safety and health standards;
employees understand the schedule;
overtime treatment is clear;
the arrangement is documented;
vulnerable workers are protected;
the arrangement complies with labor rules and advisories.

A poorly designed compressed workweek may result in overtime claims.

XXXV. Payroll Calendar Examples

Example 1: Simple Annual Estimate

Employee works 3 days per week.

[ 3 \times 52 = 156 ]

Annual scheduled workdays: 156

Example 2: Daily Rate to Annual Pay

Employee earns ₱1,200 per day and works 156 days.

[ ₱1,200 \times 156 = ₱187,200 ]

Annual basic salary: ₱187,200

Example 3: Average Monthly Equivalent

[ 156 \div 12 = 13 ]

Average monthly workdays: 13

If daily rate is ₱1,200:

[ ₱1,200 \times 13 = ₱15,600 ]

Average monthly equivalent: ₱15,600

Example 4: Annual Hours

Employee works 3 days per week, 8 hours per day.

[ 3 \times 52 \times 8 = 1,248 ]

Annual working hours: 1,248

Example 5: Exact Count

Employee works Tuesday, Thursday, and Saturday.

The employer should count the number of Tuesdays, Thursdays, and Saturdays in the relevant year. The result may be 156, 157, or 158 depending on the calendar and whether the year is a leap year.

XXXVI. Treatment of Holidays in Annual Computation

There are several possible annual day counts, and each serves a different purpose.

A. Scheduled Working Days

This includes all days the employee is normally scheduled to work, even if some are holidays.

Formula:

[ \text{Scheduled Days} = \text{Actual count of scheduled weekdays in the year} ]

Use this for schedule planning.

B. Actual Days Worked

This excludes holidays, leaves, absences, and days not actually worked.

Formula:

[ \text{Actual Days Worked} = \text{Scheduled Days} - \text{Non-worked Scheduled Days} ]

Use this for attendance-based payroll.

C. Paid Days

This includes actual workdays plus paid holidays and paid leave.

Formula:

[ \text{Paid Days} = \text{Actual Days Worked} + \text{Paid Holidays} + \text{Paid Leave Days} ]

Use this for payroll and benefit computations.

D. Benefit-Creditable Days

This depends on the benefit involved. Some benefits are based on basic salary earned, some on length of service, and some on company policy.

XXXVII. Documentation Requirements

To avoid disputes, employers should put the three-day workweek arrangement in writing.

The written agreement or policy should state:

workdays;
work hours;
meal period;
rest days;
daily or monthly rate;
holiday treatment;
overtime treatment;
leave entitlement;
social benefit contributions;
13th month pay basis;
schedule change rules;
attendance rules;
whether the arrangement is part-time or compressed;
whether the employee may work additional days;
whether work on non-scheduled days requires prior approval.

Written clarity is especially important for payroll compliance and labor disputes.

XXXVIII. Sample Clause for a Three-Day Workweek

A simple employment clause may read:

The employee shall work three days per week, every Monday, Wednesday, and Friday, from 8:00 a.m. to 5:00 p.m., with a one-hour meal period. The employee’s regular scheduled workdays shall be computed based on the actual number of Mondays, Wednesdays, and Fridays falling within the calendar year or applicable payroll period. Compensation, holiday pay, leave, overtime, and statutory benefits shall be administered in accordance with Philippine labor law and company policy.

For a compressed schedule, the clause should be more specific and should address longer hours, overtime treatment, consent, safety, and compliance with labor standards.

XXXIX. Common Mistakes in Computation

1. Assuming the Annual Count Is Always 156

The 156 figure is a good estimate, but exact annual working days may be 157 or 158 depending on the calendar and schedule.

2. Confusing Scheduled Days With Paid Days

A scheduled workday is not always a paid day, and a paid day is not always an actual day worked.

3. Ignoring Holidays

Holidays can affect pay even if they do not change the schedule.

4. Treating Part-Time Employees as Having No Benefits

Part-time employees may still be entitled to labor standards and statutory benefits.

5. Using the Wrong Daily Rate Denominator

For monthly-paid three-day employees, using a five-day or six-day denominator may produce unfair or unlawful deductions.

6. Failing to Define Rest Days

Unclear rest day designation can create disputes over premium pay.

7. Treating Long Daily Hours as Automatically Non-Overtime

Compressed work arrangements must be validly structured. Otherwise, hours beyond ordinary limits may trigger overtime.

8. Not Counting Actual Calendar Days for Final Pay

For resignations, terminations, or mid-year hiring, exact scheduled days should be counted.

XL. Recommended Computation Framework

For Philippine payroll and legal compliance, the best approach is:

Step 1: Identify the Schedule

Example: Monday, Wednesday, Friday.

Step 2: Identify the Period

Example: January 1 to December 31, or actual employment period.

Step 3: Count Actual Scheduled Days

Count all Mondays, Wednesdays, and Fridays in that period.

Step 4: Identify Holidays Falling on Scheduled Days

Separate regular holidays and special non-working days.

Step 5: Determine Pay Treatment

Classify each scheduled day as:

worked and paid;
not worked but paid;
not worked and unpaid;
paid leave;
unpaid leave;
holiday work;
rest day work;
overtime day.

Step 6: Compute Basic Pay

Use the employee’s daily rate, hourly rate, or monthly rate.

Step 7: Compute Statutory Benefits

Compute leave, 13th month pay, premiums, and contributions according to law and policy.

Step 8: Document the Result

Keep attendance records, payroll records, schedules, and computation sheets.

XLI. Sample Annual Computation Table

Item	Computation	Result
Workdays per week	3	3
Weeks per year	52	52
Estimated annual scheduled workdays	3 × 52	156
Average monthly workdays	156 ÷ 12	13
Hours per day	8	8
Estimated annual working hours	156 × 8	1,248

This table gives a general estimate. For exact payroll, count actual scheduled days in the calendar year.

XLII. Conclusion

For a three-day workweek in the Philippines, the basic annual working day computation is:

[ 3 \times 52 = 156 ]

Thus, the standard estimate is 156 working days per year.

However, this is only the starting point. The exact count may be 156, 157, or 158, depending on the calendar year, leap year, and the specific weekdays assigned. For legal and payroll purposes, employers should count the actual scheduled workdays in the relevant period.

A proper computation must distinguish between scheduled working days, actual days worked, paid days, rest days, holidays, leave days, and benefit-creditable days. This distinction is essential under Philippine labor law because a three-day workweek affects wage computation, holiday pay, premium pay, overtime, leave, 13th month pay, social benefit contributions, and final pay.

The safest legal approach is to put the arrangement in writing, count the actual scheduled days, comply with minimum labor standards, and administer benefits consistently with Philippine law and company policy.
