In Philippine labor and civil service law, the conversion of unused vacation leave and sick leave into cash—commonly referred to as “monetization,” “commutation,” or “terminal leave pay”—is governed by distinct rules depending on whether the employee belongs to the private sector or the public sector. These rules balance the employee’s right to rest and recovery with the employer’s operational needs and the State’s fiscal responsibility. The legal framework draws primarily from the Labor Code of the Philippines for private employees and the Civil Service rules, as implemented by the Civil Service Commission (CSC) and the Department of Budget and Management (DBM), for government personnel.

I. Private Sector Employees

The Labor Code (Presidential Decree No. 442, as amended) does not mandate the grant of paid vacation leave or sick leave to private-sector employees. The only compulsory paid leave is the five-day Service Incentive Leave (SIL) under Article 95, available after one year of service to rank-and-file employees. However, most employers voluntarily grant vacation leave (typically 10–15 days) and sick leave (5–15 days) either through company policy, collective bargaining agreement (CBA), or individual employment contract. When such leaves are granted, the following rules on conversion apply:

Vacation Leave Commutation
Unused vacation leave is generally commutable to cash. The Omnibus Rules Implementing the Labor Code expressly recognize that vacation leave credits earned but not used may be converted into cash at the employee’s option or upon demand, subject to the employer’s established policy. The rate of conversion is the employee’s daily rate (basic salary divided by the number of working days in the month). Many companies monetize unused vacation leave at the end of each year or upon the employee’s written request.
Sick Leave Non-Commutability
Sick leave is intended exclusively for actual illness or medical confinement and is therefore non-commutable while the employee remains in service. The policy rationale is to prevent abuse and to ensure the leave serves its restorative purpose. An employer may not, as a general rule, pay cash in lieu of sick leave unless the company handbook, CBA, or employment contract explicitly allows it. In the absence of such provision, unused sick leave simply lapses or is carried over to the following year, depending on company policy.
Terminal Leave Pay upon Separation
Upon resignation, retirement, dismissal (without just cause), or any other mode of separation, an employee is entitled to the cash equivalent of all accrued but unused vacation leave. Sick leave is likewise payable if the company policy treats it as accruable and payable upon separation. The Supreme Court has consistently ruled that accrued leaves form part of the employee’s earned compensation and must be paid upon termination (e.g., Labor Congress of the Philippines v. NLRC, G.R. No. 123290). The computation uses the employee’s final basic daily rate multiplied by the number of unused days.
Service Incentive Leave (SIL) Monetization
The five-day SIL is always commutable. An employee may opt to receive cash in lieu of actual leave or accumulate and use it later. Upon separation, any unused SIL must be paid in full.
Tax Treatment
Monetized vacation leave and terminal leave pay are subject to withholding tax on compensation. However, if the monetization occurs upon retirement under a qualified private retirement plan duly registered with the Bureau of Internal Revenue, the amount may be exempt up to the limits provided by law.

II. Public Sector / Government Employees

Government service is governed by the Administrative Code of 1987 (Book V), CSC rules, and DBM circulars. All appointive and elective officials and employees in the civil service, including those in government-owned or controlled corporations with original charters, earn leave credits at the rate of 1.25 days of vacation leave and 1.25 days of sick leave for every month of service (15 days each per year after the first year).

Monetization While in Service
- Vacation Leave Only. An employee may monetize a maximum of ten (10) days of vacation leave credits per calendar year. Monetization is subject to the following conditions:
  (a) the employee must have at least ten (10) days of accumulated vacation leave;
  (b) the agency head must approve the application;
  (c) funds must be available in the agency’s budget; and
  (d) the employee must have rendered at least one year of continuous service.
- Sick Leave. Sick leave credits cannot be monetized while the employee is still in the service. The prohibition is absolute to preserve the leave for genuine medical needs.
Terminal Leave Pay upon Separation or Retirement
Upon retirement, resignation, death, or any other mode of separation from the service (except for cause with forfeiture), an employee is entitled to the full cash value of all accumulated vacation leave and sick leave credits. This is known as “terminal leave pay.”
- Computation: Current daily rate (monthly salary ÷ 22 working days) multiplied by total unused leave days.
- The amount is released only after clearance from all money and property accountabilities.
- Terminal leave pay is paid in lump sum and is subject to withholding tax, except when exempted under specific retirement laws (e.g., GSIS or special retirement plans).
Special Rules
- Teachers and DepEd Personnel. Public school teachers are entitled to the same leave credits but enjoy additional privileges under Republic Act No. 4670 (Magna Carta for Public School Teachers). Monetization follows the general CSC rules.
- Local Government Units (LGUs). LGUs follow the same monetization ceilings and procedures but must secure DBM approval for the funding source.
- Uniformed Personnel (AFP, PNP, BJMP, BFP). Special leave laws apply, but terminal leave monetization upon retirement remains mandatory and follows the same rate of pay.
- Forfeiture. Leave credits are forfeited if the employee is dismissed for gross misconduct or if the employee fails to apply for terminal leave within the prescribed period after separation.
Forced Leave and Leave Credit Ceiling
If an employee accumulates ten (10) or more days of vacation leave, the agency head may require the employee to use at least five (5) days of vacation leave to prevent excessive accumulation. This does not affect the employee’s right to monetize the remaining ten days.

III. Procedural Requirements Common to Both Sectors

Written Application. Monetization or terminal leave claims must be supported by a written request and certification of leave credits from the Human Resources unit.
Payroll Processing. Payment is effected through the regular payroll system or as a special check.
Record-Keeping. Employers and agencies must maintain accurate leave cards or electronic records, which serve as prima facie evidence in disputes.
Dispute Resolution. Private-sector claims are cognizable by the National Labor Relations Commission (NLRC) or the Labor Arbiter. Public-sector claims are resolved through the agency grievance machinery, CSC, or the Office of the Ombudsman.

IV. Prohibited Practices

Employers (private or public) may not compel an employee to monetize vacation leave against his or her will.
Conversion of sick leave into vacation leave, or vice versa, is not allowed.
Deduction of unused leave from final pay is prohibited unless the employee has been overpaid or has outstanding obligations.
Denial of terminal leave pay upon separation constitutes illegal withholding of wages.

The rules on leave monetization reflect a clear legislative policy: vacation leave is both a rest benefit and a form of earned compensation that may be liquidated in cash, while sick leave is strictly protective in nature. Any deviation from these principles—whether by employer policy or agency memorandum—must be expressly authorized by law or by a valid collective bargaining agreement. Employees and employers alike are therefore enjoined to familiarize themselves with the applicable sector-specific regulations to ensure compliance and to protect the integrity of the leave privilege.
