Undertime is one of the most overlooked yet crucial aspects of payroll management in the Philippines. Ensuring accurate undertime computation is essential for maintaining compliance with labor laws and avoiding disputes between employers and employees. This guide will help HR professionals and employers understand undertime computation under Philippine law and how to automate this process through GreatDayHR.
What Is Undertime?
Undertime occurs when an employee works fewer hours than the standard work schedule set by the company. For example, if an employee is required to work eight hours but only completes six and a half, the missing 1.5 hours is considered undertime.
Legal Basis
Under Article 88 of the Philippine Labor Code, “Undertime work on any particular day shall not be offset by overtime work on any other day.” This means an employee’s undertime hours cannot be balanced out with overtime hours from another shift. Employers must treat undertime separately and deduct corresponding wages accordingly.
Common Causes of Undertime
Undertime can happen for various reasons:
- Leaving work early for personal or emergency matters
- Arriving late and failing to complete the required hours
- Logging out early in remote or hybrid setups
- Shortened work due to company activities or system downtime
In all cases, HR must record undertime accurately to ensure fair pay and compliance.
How to Compute Undertime: Step-by-Step
Computing undertime deductions depends on the employee’s salary type and work schedule. Here’s a simple step-by-step guide:
Step 1: Identify the Employee’s Pay Type
Determine if the employee is monthly-paid or daily-paid.
- For daily-paid employees: Use the agreed daily rate.
- For monthly-paid employees: Convert the monthly salary to a daily rate using the standard DOLE divisor.
Step 2: Compute Daily and Hourly Rates
For monthly-paid employees:
Daily Rate = (Monthly Salary × 12) ÷ DOLE Divisor
Hourly Rate = Daily Rate ÷ 8
Per-Minute Rate = Hourly Rate ÷ 60
Step 3: Compute Undertime Deduction
Undertime Deduction = Per-Minute Rate × Number of Undertime Minutes
Example Computation
- Monthly Salary: ₱20,000
- DOLE Divisor: 313 (for a 5-day workweek)
- Daily Rate = (20,000 × 12) ÷ 313 = ₱766.77
- Hourly Rate = ₱766.77 ÷ 8 = ₱95.85
- Per-Minute Rate = ₱95.85 ÷ 60 = ₱1.598
- Undertime: 1 hour 45 minutes = 105 minutes
Undertime Deduction: ₱1.598 × 105 = ₱167.79
Thus, ₱167.79 should be deducted from the employee’s pay for that day.
Important Guidelines on Undertime
1. No Offsetting Allowed
Employers cannot offset undertime with overtime, even if the employee works extra hours later in the week.
2. Written Policy Required
Companies should include clear undertime rules in their employee handbook or HR policy to maintain transparency.
3. Document Every Instance
All undertime occurrences must be recorded in the attendance system or timesheet for audit and compliance.
4. Apply Correct Divisors
Ensure that the DOLE divisor (261 or 313) matches the company’s work schedule—6-day or 5-day workweek.
