In the Philippines, the security of tenure is a constitutionally guaranteed right. Article XIII, Section 3 of the 1987 Constitution ensures that workers are entitled to security of tenure, meaning an employee cannot be dismissed except for a just or authorized cause and only after the observance of due process.

When an employer terminates an employee without following the prescribed legal procedures, it constitutes "Illegal Dismissal" or a violation of "Procedural Due Process."

I. The Two-Pronged Requirement for Valid Dismissal

For a termination to be valid under the Labor Code of the Philippines, the employer must comply with two essential requirements:

Substantive Due Process: The dismissal must be based on a Just Cause (fault of the employee) or an Authorized Cause (business necessity).
Procedural Due Process: The employer must follow the "Two-Notice Rule" for just causes or the "30-day Notice Rule" for authorized causes.

II. Procedural Due Process: The Requirements

The procedure varies depending on the ground for termination:

1. For Just Causes (Art. 297, Labor Code)

(Serious misconduct, willful disobedience, gross and habitual neglect of duty, fraud/breach of trust, or commission of a crime)

The First Written Notice (Notice to Explain): This must specify the grounds for termination and give the employee a reasonable opportunity (at least 5 calendar days) to explain their side.
The Hearing or Conference: The employer must provide the employee a chance to respond to the charge, present evidence, or rebut the evidence against them.
The Second Written Notice (Notice of Decision): After considering the explanation, the employer must serve a written notice indicating that all circumstances have been considered and the grounds to justify severance have been established.

2. For Authorized Causes (Art. 298-299, Labor Code)

(Redundancy, retrenchment, installation of labor-saving devices, or closure of business)

The 30-Day Notice: The employer must serve a written notice to both the employee and the Department of Labor and Employment (DOLE) at least one month before the intended date of termination.

III. Rights of an Employee Terminated Without Due Process

If an employee is dismissed without due process, they are entitled to specific legal protections, even if a valid cause for dismissal existed.

1. Right to Contest Dismissal

The employee has the right to file a complaint for Illegal Dismissal before the Labor Arbiter of the National Labor Relations Commission (NLRC). The prescriptive period for filing is four (4) years from the date of termination.

2. Right to "Nominal Damages" (The Agabon Doctrine)

If there was a valid cause for dismissal (e.g., the employee actually stole), but the employer failed to follow procedure (no notice/hearing), the dismissal is upheld, but the employer is liable to pay Nominal Damages.

For lack of due process in Just Causes: Usually ₱30,000.
For lack of due process in Authorized Causes: Usually ₱50,000.

3. Right to Reinstatement and Full Backwages

If the dismissal is found to be illegal because there was neither substantive nor procedural due process:

Reinstatement: Restoring the employee to their former position without loss of seniority rights.
Full Backwages: Payment of wages, inclusive of allowances and other benefits, computed from the time compensation was withheld up to the time of actual reinstatement.

IV. Remedies Available to the Employee

When an employee is illegally terminated, the following cumulative remedies may be sought:

1. Separation Pay in Lieu of Reinstatement

If reinstatement is no longer feasible due to "strained relations" between the employer and employee, or if the position no longer exists, the court may award Separation Pay (usually one month's salary for every year of service) instead of reinstatement.

2. Moral and Exemplary Damages

These are awarded if the dismissal was attended by bad faith, fraud, or was oppressive to labor, or done in a manner contrary to morals, good customs, or public policy.

3. Attorney’s Fees

In cases of unlawful withholding of wages or illegal dismissal, the employee may be awarded attorney’s fees equivalent to 10% of the total monetary award.

4. Burden of Proof

In termination cases, the burden of proof rests solely on the employer. The employer must prove by "substantial evidence" that the dismissal was for a valid cause and that due process was observed. If the employer fails to prove this, the dismissal is deemed illegal.

Summary Table: Consequences of Non-Compliance

Scenario	Status of Dismissal	Primary Remedy/Liability
No Just Cause + No Due Process	Illegal	Reinstatement + Full Backwages
With Just Cause + No Due Process	Valid (but irregular)	Employment ends + Nominal Damages (₱30k)
With Authorized Cause + No Due Process	Valid (but irregular)	Separation Pay + Nominal Damages (₱50k)
