Introduction

In the Philippine labor landscape, employees who resign from their positions due to illness face unique considerations regarding their entitlements. The Labor Code of the Philippines (Presidential Decree No. 442, as amended) serves as the primary legal framework governing employment relationships, including terminations and resignations. While resignation is generally voluntary and does not automatically trigger separation pay, circumstances involving illness can intersect with provisions on health-related terminations, work-related injuries, and social security benefits. This article explores the full spectrum of benefits available to employees resigning due to illness, including statutory entitlements, procedural requirements, and potential remedies under Philippine law.

The discussion is grounded in the principle that labor laws favor the protection of workers, as enshrined in Article XIII, Section 3 of the 1987 Philippine Constitution, which mandates the state to afford full protection to labor and promote social justice. Key agencies involved include the Department of Labor and Employment (DOLE), Social Security System (SSS), Philippine Health Insurance Corporation (PhilHealth), and Pag-IBIG Fund, each administering specific benefits that may apply post-resignation.

Legal Basis for Resignation Due to Illness

Resignation due to illness is classified as voluntary termination under Article 300 (formerly Article 285) of the Labor Code, which allows an employee to terminate employment without just cause by serving a written notice at least one month in advance. However, if the illness renders the employee incapable of continuing work, it may blur the lines with involuntary separation scenarios.

A critical distinction arises under Article 299 (formerly Article 284) of the Labor Code, which addresses termination due to disease. This provision permits an employer to terminate an employee if a competent public health authority certifies that the employee's disease is of such nature or stage that it cannot be cured within six months even with proper medical treatment, and continued employment is prohibited by law or prejudicial to the employee's health or that of co-employees. In such cases, the employee is entitled to separation pay equivalent to at least one month's salary or one-half month's salary for every year of service, whichever is greater, with fractions of at least six months considered as one whole year.

For employees resigning proactively due to illness—before an employer initiates termination—the entitlement to separation pay is not automatic. Courts, including the Supreme Court in cases like Meralco v. NLRC (G.R. No. 114129, 1995), have ruled that voluntary resignation typically forfeits separation pay unless provided by company policy, collective bargaining agreement (CBA), or if the resignation is effectively a constructive dismissal due to unbearable working conditions exacerbated by illness. However, if the illness is work-related, the employee may claim benefits under the Employees' Compensation Program (ECP) administered by the SSS or Government Service Insurance System (GSIS) for public sector workers, as per Presidential Decree No. 626.

DOLE Department Order No. 147-15 emphasizes fair treatment in terminations, including those related to health, and prohibits discrimination against employees with illnesses under Republic Act No. 7277 (Magna Carta for Disabled Persons), as amended by Republic Act No. 10524.

Statutory Benefits Upon Resignation

Employees resigning due to illness are entitled to several accrued and pro-rated benefits, computed up to the last day of employment. These include:

1. Final Wages and Accrued Salaries

The employee must receive all unpaid wages for work performed, including overtime, holiday pay, and night shift differentials, if applicable. Under Article 116 of the Labor Code, wages must be paid promptly, and failure to do so may result in penalties.
If illness prevents the employee from completing the notice period, the employer may waive the one-month notice or allow the employee to resign immediately without liability for damages, as per jurisprudence in Erectors, Inc. v. NLRC (G.R. No. 104215, 1993).

2. Pro-Rated 13th Month Pay

Mandated by Presidential Decree No. 851, the 13th month pay is equivalent to one-twelfth of the basic salary earned within a calendar year. For resignations mid-year, it is pro-rated based on months worked. For example, an employee resigning after six months is entitled to half of one month's basic salary as 13th month pay.
This benefit is non-negotiable and must be paid within the final paycheck or upon clearance.

3. Service Incentive Leave (SIL) Conversion

Under Article 95 of the Labor Code, employees with at least one year of service are entitled to five days of paid SIL annually. Unused SIL at the time of resignation must be commuted to cash, calculated as (unused days / 25 working days per month) x daily rate.
If the illness qualifies as a valid reason for leave, any prior sick leaves taken may affect this computation, but unused portions remain convertible.

4. Other Pro-Rated Bonuses and Allowances

Company-specific bonuses, such as performance or Christmas bonuses, may be pro-rated if stipulated in the employment contract or company policy. However, these are not statutorily required unless part of a CBA.

Social Security and Health-Related Benefits

Resignation does not terminate membership in social security programs, allowing continued access to benefits if contributions have been made.

1. SSS Sickness Benefits

Under Republic Act No. 11199 (Social Security Act of 2018), employees who have paid at least three monthly contributions in the 12 months preceding the semester of sickness are eligible for daily sickness allowance equivalent to 90% of the average daily salary credit, for up to 120 days per year.
For resignation due to illness, the benefit can be claimed if the sickness occurs before or immediately after resignation, provided the employee notifies the employer and SSS within five days of the illness. Required documents include a medical certificate and SSS Form CLD-9N.

2. SSS Disability Benefits

If the illness results in permanent partial or total disability, the employee may qualify for a monthly pension or lump-sum payment under the SSS. Permanent total disability (e.g., loss of limbs or mental incapacity) entitles the member to a pension based on years of contribution, with a minimum of 36 months required for eligibility.
Work-related illnesses fall under the ECP, providing additional compensation without the need to prove employer fault, as per PD 626. Examples include occupational diseases like tuberculosis or cancer linked to workplace exposure.

3. PhilHealth Benefits

Republic Act No. 11223 (Universal Health Care Act) ensures coverage for hospitalization and outpatient care. Employees resigning due to illness can continue as voluntary members by paying premiums.
Benefits include inpatient care (up to 45 days per year), outpatient services, and specific packages for illnesses like dengue or pneumonia. Claims require a PhilHealth Claim Form 1 and medical certificates, processable even post-resignation if the illness manifested during employment.

4. Pag-IBIG Fund Benefits

Under Republic Act No. 9679, employees may withdraw their Pag-IBIG savings upon resignation, including employee contributions, employer counterparts, and dividends. If illness leads to total permanent disability, a provident benefit claim is available.
For housing loans or multi-purpose loans, resignation due to illness may qualify for loan restructuring or moratoriums under Pag-IBIG guidelines.

Benefits for Work-Related Illnesses

If the illness is attributable to employment, additional protections apply:

Employees' Compensation Claims: Administered by SSS/GSIS, these cover medical expenses, rehabilitation, and death benefits if the illness worsens fatally. The presumption of compensability under PD 626 shifts the burden to the employer to prove otherwise.
Supreme Court Rulings: In GSIS v. De Leon (G.R. No. 186262, 2010), the Court upheld compensability for illnesses aggravated by work conditions, even if not listed in the occupational disease annex.

Non-work-related illnesses do not trigger these but may still qualify for general SSS/PhilHealth benefits.

Procedural Requirements and Employer Obligations

Upon resignation:

Notice and Clearance: The employee must submit a resignation letter citing illness, supported by a medical certificate. The employer processes final pay within 30 days, as per DOLE rules, and issues a Certificate of Employment under Article 294 (formerly 279).
Quitclaim: Employees should cautiously sign quitclaims, as they may waive rights if signed under duress, per Goodrich Manufacturing Corp. v. Ativo (G.R. No. 188002, 2010).
Tax Implications: Benefits like separation pay for health reasons may be tax-exempt under Revenue Regulations No. 2-98 if certified by a public health authority.
Dispute Resolution: Grievances can be filed with DOLE's National Labor Relations Commission (NLRC) for illegal dismissal claims if the resignation is contested as constructive dismissal, with remedies including backwages and reinstatement.

Special Considerations

CBA and Company Policies: These may provide enhanced benefits, such as extended medical leave or voluntary separation packages for health reasons.
Public Sector Employees: Governed by Civil Service rules and GSIS, they enjoy similar benefits with additional retirement options under Republic Act No. 8291.
Migrant Workers: Overseas Filipino Workers (OFWs) resigning due to illness may claim under the Migrant Workers Act (Republic Act No. 10022), including repatriation and medical assistance.
COVID-19 and Pandemic-Related Illnesses: DOLE Advisory No. 17-20 series recognizes COVID-19 as compensable if contracted at work, extending to post-resignation claims.

Conclusion

Employees in the Philippines resigning due to illness are safeguarded by a robust framework of labor and social security laws, ensuring access to financial, medical, and compensatory benefits. While voluntary resignation limits some entitlements like separation pay, intersections with health-related provisions and social insurance programs provide comprehensive support. Employers must comply diligently to avoid liabilities, and employees are encouraged to document their conditions thoroughly to maximize claims. This balance reflects the Philippine commitment to worker welfare amid health challenges.
