Introduction

In Philippine practice, a fitness-to-work classification is the formal medical assessment of whether a worker is presently capable of performing work, whether with no restrictions, with temporary or permanent restrictions, or not at all. It appears in many settings: pre-employment medical examination, return-to-work after illness or injury, occupational disease management, disability and compensation claims, seafarer medical repatriation cases, mental health episodes, pregnancy-related work adjustments, and company clinic referrals.

The phrase itself is used far more often in workplace medicine and human resources practice than in statute. Philippine law does not contain one single codified “Fitness-to-Work Act” that defines all classifications in one place. Instead, the legal basis is distributed across the Constitution, the Labor Code, occupational safety and health law, social legislation, disability law, mental health law, data privacy law, civil law principles, and sector-specific rules, plus a large body of jurisprudence.

That means any proper legal analysis must distinguish between:

Medical fitness-to-work findings
Employment consequences of those findings
Compensation or benefit consequences of those findings
Procedural and evidentiary rules on who may issue, review, or dispute the finding

Those four layers are often confused in practice. A worker may be medically “fit to work with restrictions,” yet still be entitled to accommodation, sick leave, SSS benefits, employees’ compensation, or redeployment. Conversely, a worker may be declared “unfit” by a company physician, but that declaration does not automatically make a dismissal lawful.

I. Concept of Fitness to Work in Philippine Law

A. Meaning

In Philippine employment practice, fitness to work generally refers to a physician’s assessment that an employee is:

Fit to work — capable of performing the job without restriction
Fit to work with restrictions — capable of working subject to limits, accommodations, or temporary modification
Temporarily unfit to work — not presently fit, but expected to recover or improve
Permanently unfit to work — medically unable to resume the previous work, or any work of the same nature, depending on context

These labels matter because they affect:

continuation or suspension of work
sick leave and salary questions
return-to-work clearance
transfer or reassignment
work accommodation
medical confidentiality
disability benefit claims
validity of dismissal for disease
liability for discrimination or unfair labor practice
compensation under ECC/SSS or private employment contracts

B. Not purely a medical issue

Under Philippine law, fitness-to-work is not only a clinical judgment. It becomes a legal issue because a classification can trigger or justify action under:

management prerogative
occupational safety obligations
mandatory separation for disease
disability compensation
anti-discrimination principles
privacy and informed consent requirements

The medical finding is therefore only one part of the legal analysis.

II. Constitutional and Policy Foundations

A. Social justice and protection to labor

The Constitution’s labor-protective framework is the deepest legal basis behind fitness-to-work rules. It recognizes:

full protection to labor
humane conditions of work
security of tenure
health and safety in the workplace
social justice
dignity of every worker

These constitutional values explain why Philippine law does not allow employers to treat a medical classification as a free pass to exclude, stigmatize, or terminate workers. Any fitness determination must be tied to legitimate safety, medical, and business reasons, and must respect due process and worker dignity.

B. Police power and workplace safety

The State also has an interest in protecting co-workers, the public, and enterprise operations from genuine health and safety risks. This is why medical examinations, occupational health programs, and restrictions on unsafe deployment are legally recognized.

So the Philippine framework balances two interests:

the worker’s right to keep employment and be treated fairly
the employer’s right and duty to maintain a safe workplace

III. Primary Statutory Sources

A. Labor Code of the Philippines

The Labor Code is one of the principal foundations, especially in cases where illness becomes the basis for separation.

1. Disease as an authorized cause for termination

The key rule is the provision allowing termination where:

the employee is suffering from a disease; and
continued employment is prohibited by law or is prejudicial to the employee’s health or to the health of co-employees

This is the clearest statutory anchor for fitness-to-work disputes.

But that authority is tightly limited. Termination for disease is lawful only if the legal requirements are met, including the requirement that a competent public health authority certify the nature of the disease and that it cannot be cured within a period prescribed by law or cannot be cured within a reasonable time even with proper medical treatment, depending on the formulation applied in practice and jurisprudence.

This means:

a mere company clinic opinion is not enough by itself to justify dismissal for disease
the illness must be real, supported by evidence
the risk or incapacity must be serious enough to matter legally
due process must still be observed

2. Security of tenure implications

A worker cannot be dismissed just because an employer prefers a healthier employee. If the employer uses a medical finding to remove someone from service, the dismissal must fall under a lawful cause and follow due process. Otherwise, the worker may be illegally dismissed.

Thus, a fitness-to-work classification is not self-executing. It must be translated into legally proper action.

B. Implementing Rules of the Labor Code

The implementing rules historically flesh out the disease-termination mechanism. Their importance lies in requiring certification from a competent public health authority and in framing when disease-based dismissal is lawful.

This is critical because many employers mistakenly rely only on:

company doctor memos
clinic notes
internal HR clearance forms
HMO opinions

Those may be relevant evidence, but for disease termination they do not automatically substitute for the statutory requirement involving a competent public health authority.

C. Occupational Safety and Health Standards Law

The Occupational Safety and Health Standards Act and related regulations are another major legal basis. These laws impose on employers the duty to maintain a safe and healthful workplace, including occupational health services and preventive measures.

From a fitness-to-work perspective, OSH law supports:

pre-employment and periodic medical assessments where justified
post-illness or post-injury return-to-work evaluation
restrictions on hazardous assignments
monitoring of occupational diseases
removal from exposure where medically necessary
referral to occupational health personnel

The employer may therefore require medical clearance when job demands or workplace hazards make it necessary. This is especially true in safety-sensitive work such as:

driving and transport
heavy machinery
work at heights
chemical exposure
health care
food handling
security work
seafaring
aviation-related positions
high-risk industrial operations

But OSH law does not authorize arbitrary exclusion. The requirement must still be tied to workplace safety, job necessity, and lawful procedure.

D. Magna Carta of Disabled Persons

The disability law framework is highly relevant because some fitness-to-work classifications effectively label a worker as limited, restricted, or incapable. Philippine disability law guards against discrimination and requires equal opportunity.

A worker with a medical condition is not automatically unemployable. The law pushes analysis toward:

whether the person can still perform essential job functions
whether accommodation or reassignment is possible
whether exclusion is based on actual inability or mere stereotype

This is important because “unfit” in medical shorthand can become discriminatory in legal effect if it is used loosely or broadly.

A lawful fitness determination should therefore be function-specific and job-related, not a generalized statement that the worker is undesirable.

E. Mental Health Act

The Mental Health Act adds an important modern layer. Mental health conditions are part of fitness-to-work analysis, but the law rejects stigma and protects the rights, dignity, privacy, and autonomy of persons with mental health needs.

In practical terms, this means:

mental health episodes may justify assessment and temporary leave where safety or clinical necessity exists
employers should avoid automatic conclusions that psychological treatment equals unfitness
confidentiality is especially important
return-to-work should consider recovery, accommodation, and anti-discrimination principles

The employer may require a fit-to-work certificate after serious mental health leave if job safety and functioning reasonably require it. But the process must not humiliate, discriminate against, or expose the employee’s diagnosis beyond what is necessary.

F. Data Privacy Act

Fitness-to-work processes inherently involve sensitive personal information. Health data is protected as sensitive personal information under Philippine data privacy law.

This has major consequences:

employers cannot collect unlimited medical information
only data necessary for lawful workplace purposes should be processed
disclosure should be need-to-know
HR should not circulate diagnoses casually
supervisors generally need work restrictions and clearance status, not full medical history
consent, legitimate basis, retention limits, and safeguards matter

A fit-to-work form that states “fit,” “fit with restrictions,” or “temporarily unfit” may be lawful. A company-wide email naming a worker’s diagnosis usually is not.

G. Social Security Act and Sickness/Disability Benefits

Fitness-to-work classifications intersect with SSS in two ways:

Sickness benefit — when a worker is temporarily unable to work due to illness or injury
Disability benefit — when there is permanent partial or permanent total disability

These benefit systems do not perfectly mirror employer classifications. A worker may be on SSS sickness benefit while awaiting work clearance, or may later qualify for disability benefit if impairment becomes permanent.

Therefore, “fit to work” in company practice is not identical to “not disabled” under social legislation.

H. Employees’ Compensation Law and ECC Rules

For work-related sickness, injury, or death, the Employees’ Compensation system matters greatly. It recognizes compensable occupational disease and work-related injury. Here, medical fitness classification affects:

entitlement to temporary total disability benefits
permanent partial disability or permanent total disability
return-to-work timing
rehabilitation
employer reporting obligations

Again, the benefit classification and the HR classification are related but not identical.

I. Civil Code and Tort Principles

Civil law principles may also apply. An employer who negligently declares a worker fit despite obvious danger, or who unlawfully excludes a worker without basis, may face liability under general civil law theories depending on the facts.

Similarly, a physician issuing careless or baseless certifications may face administrative, civil, or even criminal consequences in extreme cases.

IV. Administrative and Regulatory Sources

A. DOLE issuances and occupational health practice

The Department of Labor and Employment has long issued rules and standards on occupational health, company physicians, and workplace safety. These support the use of medical evaluations for hazard control, worker placement, and return-to-work protocols.

They matter because they help establish when a medical exam is:

reasonably required by the job
part of a valid workplace health program
evidence of employer compliance or noncompliance

B. DOH and public health authority involvement

Where disease termination is involved, the role of a competent public health authority is central. This usually points toward government medical authority rather than purely private internal certification.

That requirement reflects legislative distrust of unilateral employer declarations.

C. Civil Service and public sector rules

In government employment, fitness-to-work may also be governed by Civil Service rules, leave regulations, and agency medical processes. The broad principles are similar, but procedures can differ from the private sector.

D. POEA/DMW and seafarer rules

For overseas Filipino seafarers, fitness-to-work has a particularly dense legal framework. The standard employment contract, company-designated physician system, repatriation rules, and dispute mechanisms produce a specialized body of law. In that area, the classification often determines:

temporary disability
permanent disability grading
entitlement to contractual benefits
obligation to report for post-employment medical examination
conflict between company-designated physician and personal doctor
necessity of a third doctor mechanism

This is one of the most litigated areas of Philippine fitness-to-work law.

V. Jurisprudential Framework

Philippine jurisprudence supplies the most operational rules because statutes are general while disputes are highly fact-specific.

A. Dismissal for disease requires strict compliance

The Supreme Court has repeatedly treated disease-based dismissal as valid only upon strict observance of statutory requirements. Core themes in the cases include:

the disease must be sufficiently established
there must be proper certification by the required authority
the disease must be of such nature or stage that continued employment is prohibited or prejudicial
procedural due process must be observed

A company doctor’s statement alone is often insufficient for lawful termination under the disease provision.

B. “Unfit to work” is not automatically “validly dismissed”

A recurring mistake in practice is to assume that once a physician says “unfit to work,” the employment relationship may simply end. Jurisprudence rejects that shortcut.

Questions remain:

Is the finding temporary or permanent?
Does it relate to the current job only, or all work?
Can the employee be accommodated?
Was a public health certification obtained where required?
Was notice and opportunity to respond given?
Was separation pay or other benefit due?
Was the finding contradicted by another doctor?

C. The evidentiary weight of company physicians

Company physicians are important, but not infallible. Their findings are evidence, often substantial evidence in administrative settings, but not conclusive in all contexts.

Courts examine:

basis of the medical opinion
actual examination performed
specialty and competence
consistency of reports
relation to the job’s actual demands
whether the assessment is temporary or final
whether the worker’s own physician issued a contrary opinion

D. Seafarer cases: the company-designated physician and third doctor rule

In maritime employment, Philippine jurisprudence has developed detailed rules on disability assessment and the conflict between medical opinions. Major recurring doctrines include:

the seafarer must usually submit to the company-designated physician after repatriation
the company-designated physician has the initial right to assess fitness or disability within the applicable periods
if the seafarer’s doctor disagrees, referral to a mutually agreed third doctor may become decisive under the contract
failure to follow the third-doctor process may affect the weight of competing medical opinions, depending on the facts and line of cases

This area is highly technical because contractual, statutory, and case law rules interact.

E. Temporary disability versus permanent disability

Philippine case law often wrestles with time periods. A worker may be temporarily disabled but later deemed permanently disabled if inability to work extends beyond recognized periods or if no definite fit-to-work declaration is issued within the applicable framework.

This is especially prominent in seafarer and compensation litigation.

F. Due process always matters

Even where medical grounds exist, the worker is ordinarily entitled to procedural fairness. In private employment, that commonly means notice and an opportunity to be heard before termination, unless the context is not disciplinary but still requires statutory compliance.

VI. Typical Fitness-to-Work Classifications in Philippine Practice

There is no universally mandated national taxonomy for all employers, but the following are common:

1. Fit to work

The worker may resume or start work without limitation.

Legal effect: generally allows deployment, subject to ordinary conditions.

2. Fit to work with restrictions

The worker can work but should avoid certain tasks, exposures, schedules, or physical demands.

Examples:

no lifting beyond a set weight
no night shift temporarily
no exposure to dust or solvents
no driving
no overtime
avoid prolonged standing
office-based work only
limited screen time during recovery
no solo duty during psychiatric stabilization phase

Legal effect: triggers employer consideration of accommodation, modified duty, reassignment, or temporary adjustment.

3. Temporarily unfit to work

The worker should not presently work because doing so may harm recovery, safety, or others.

Legal effect: may justify sick leave, non-deployment, temporary removal from hazardous tasks, or continued treatment and reevaluation. It does not automatically justify termination.

4. Permanently unfit to work

The worker is medically assessed as no longer able to resume the job, or sometimes any comparable job, depending on wording and context.

Legal effect: may support disability claims, possible separation on authorized grounds if legal requirements are met, insurance or contract claims, or retirement/disability processing.

5. Fit pending control or compliance

Sometimes used where a worker may work subject to medication adherence, blood pressure control, glucose control, follow-up consultation, or periodic monitoring.

Legal effect: lawful only if medically and operationally justified, and not arbitrary.

VII. The Pre-Employment Medical Examination

A. Legal basis

Pre-employment medical examination is widely accepted in Philippine practice, especially for jobs with public health or safety implications. Its legal basis comes from the employer’s legitimate interest in:

determining fitness for the specific job
reducing workplace hazards
complying with health and safety standards
preventing aggravation of preexisting conditions in hazardous assignments

B. Legal limits

Pre-employment screening is not unlimited. It should be:

related to the nature of the work
not discriminatory
respectful of privacy
not a device to exclude protected groups without valid basis

An employer may assess whether an applicant can perform essential job functions safely. It may not lawfully weaponize medical screening to impose broad exclusion unsupported by job necessity.

C. Relevance of anti-discrimination law

Conditions such as controlled hypertension, diabetes, disability, mental health history, or previous illness do not automatically justify exclusion. The issue is whether the applicant can perform the job, with or without reasonable accommodation where required by law and policy.

VIII. Return-to-Work Assessments

Return-to-work evaluations are the most common source of fitness classifications.

A. Typical triggers

after hospitalization
after prolonged sick leave
after surgery
after work injury
after infectious disease
after psychiatric leave
after pregnancy complications
after repeated absences due to illness

B. Employer’s right to require clearance

An employer usually has the right to require medical clearance before allowing resumption of duty when the illness may affect:

worker safety
co-worker safety
service reliability
legal compliance
essential performance of duties

This is stronger in hazardous or regulated industries.

C. Limits on that right

The clearance requirement must be:

job-related
consistently applied
not punitive
not used to indefinitely freeze employment without basis
respectful of confidentiality

An employer cannot use “no fit-to-work certificate, no work forever” as a hidden dismissal device when the law requires actual termination procedures.

IX. Disease as a Ground for Termination

This is the most legally sensitive area.

A. Elements

For disease-based termination to stand, Philippine law generally requires:

the employee suffers from a disease
continued employment is prohibited by law or prejudicial to health
proper certification by the required authority exists
due process is observed

B. Temporary illness is not enough

A common error is treating every prolonged illness as a lawful basis for separation. The law requires more than inconvenience to the employer.

C. Need for competent public health certification

This requirement is central and often decisive. Employers who terminate on the basis only of private medical impressions take legal risk.

D. Relation to separation pay

Disease termination is an authorized cause, so separation pay consequences may apply depending on the governing rule and facts.

E. Interaction with benefits

Even if separation is lawful, the employee may still be entitled to:

accrued salary and benefits
leave conversions where applicable
separation pay if required
SSS sickness or disability benefits
ECC compensation
insurance benefits
retirement or disability plan benefits under company policy or CBA

X. Fitness to Work and Disability Law

A. Medical unfitness versus legal disability

These are not always the same.

A person may be medically restricted but still legally employable.
A person may be disabled for benefit purposes yet still able to work in a modified role.
A person may be declared fit to work yet still have permanent impairment.

The legal system therefore distinguishes among:

capacity to perform a specific job
existence of physical or mental impairment
entitlement to monetary disability benefits
right to accommodation and non-discrimination

B. Reasonable accommodation logic

Philippine law does not have the same deeply elaborated accommodation framework as some foreign jurisdictions, but disability-protective principles support reassignment, job modification, or reasonable adjustments where feasible and not unduly burdensome.

Thus, before branding a worker “unfit,” the employer should consider whether the issue is really:

inability to do one particular task
inability to do the same job under the same conditions
or inability to do any useful work at all

Those are very different conclusions.

XI. Fitness to Work in Mental Health Cases

A. Why this area is sensitive

Mental health issues are often overgeneralized in the workplace. Philippine law, especially after the Mental Health Act, disfavors stigma-based treatment.

B. When assessment is justified

A fit-to-work evaluation may be justified where there are legitimate concerns involving:

suicidal crisis
psychosis
severe panic affecting safety
cognitive impairment affecting critical tasks
medication side effects affecting hazardous work
violent or disorganized behavior
inability to perform essential functions

C. What employers should avoid

They should avoid:

blanket bans on all employees with mental health history
public disclosure of diagnosis
forcing unnecessary details
treating therapy alone as proof of unfitness
using psychiatric referral as punishment

D. Return-to-work design

A lawful and humane process may include:

clearance from treating psychiatrist or psychologist where relevant
occupational health review
restricted duties for a period
schedule adjustment
monitoring focused on function, not gossip or stigma

XII. Infectious Disease and Public Health Context

Fitness-to-work classification became especially visible during infectious disease events. In this context, the legal basis comes from:

public health regulations
employer duty to maintain a safe workplace
lawful health screening requirements
disease-termination rules where applicable
privacy law limitations

Employers may require isolation, testing, medical clearance, or temporary non-deployment when justified by public health protocols or genuine workplace risk. But they must avoid unnecessary disclosure and overbroad exclusion once risk has passed.

XIII. Who May Issue Fitness-to-Work Determinations

A. Company physician

A company physician commonly issues return-to-work or restriction clearances. These are important operationally.

B. Treating physician

The employee’s personal doctor may issue a contrary assessment. This often occurs in labor disputes.

C. Government or public health authority

Where the Labor Code requires certification by a competent public health authority for disease termination, this authority becomes legally crucial.

D. Third doctor

In specific sectors, especially maritime employment, a third-doctor mechanism may be contractually required to resolve conflicting medical opinions.

E. Specialists

The weight of an opinion often depends on whether the physician is appropriately specialized for the condition at issue.

XIV. Evidentiary Issues

Fitness-to-work disputes are often won or lost on evidence.

Important evidence includes:

medical certificates
specialist reports
diagnostics and laboratory findings
job descriptions
actual physical demands of the work
incident reports
company clinic notes
leave records
accommodation attempts
correspondence about return-to-work
public health certification where required
CBA or company manual provisions
in seafarer cases, post-employment medical reports and contract terms

A weak medical label with no functional analysis is far less persuasive than a detailed report explaining exactly what the worker can and cannot safely do.

XV. Due Process in Employment Action Based on Fitness Findings

Even when a worker is medically restricted, the employer should still proceed legally.

A sound process usually includes:

documented medical basis
explanation of the implications to the employee
chance for the employee to submit contrary medical evidence
consideration of accommodation or reassignment where appropriate
compliance with statutory certification requirements if termination is considered
written notices and observance of procedural due process

Employers that skip these steps risk illegal dismissal findings.

XVI. Management Prerogative and Its Limits

Philippine law recognizes management prerogative in hiring, deployment, transfer, and workplace safety. Fitness-to-work assessments often fall within that prerogative.

But management prerogative is valid only if exercised:

in good faith
for legitimate business reasons
not to defeat labor rights
not in a discriminatory, retaliatory, or arbitrary manner

Thus, a “fit-to-work” policy cannot be used as a disguised mechanism for union busting, pregnancy discrimination, disability exclusion, or retaliation against sick employees.

XVII. Special Contexts

A. Pregnancy and postpartum status

Pregnancy is not illness. Restrictions must be medically grounded and lawful. Employers must avoid discriminatory exclusion while observing maternity protections and genuine medical limits.

B. High-risk jobs

For drivers, pilots, machine operators, armed personnel, and similar roles, stricter and more frequent fitness screening is easier to justify.

C. Food handlers and health care workers

Public health considerations may justify additional clearances where communicable disease risks are involved.

D. Substance use concerns

Fitness-to-work review may arise where intoxication, dependence, or treatment affects safety-critical work. Employers must balance safety, due process, rehabilitation, and privacy.

E. Seafarers

This remains the most jurisprudentially developed category, with unique rules on repatriation, medical assessment periods, and disability grading.

XVIII. Common Legal Errors in Philippine Workplace Practice

Some of the most frequent mistakes are:

1. Treating company doctor opinion as automatically final

It is important, but not always conclusive.

2. Equating “not fit today” with “ground for dismissal”

Temporary unfitness is not the same as lawful termination.

3. Ignoring the need for competent public health certification

This is fatal in many disease-termination disputes.

4. Failing to consider restrictions or accommodation

Not every medical limitation means total inability.

5. Disclosing diagnoses too broadly

This creates privacy and dignity issues.

6. Using indefinite no-work status as constructive dismissal

If the worker is effectively excluded without proper legal action, liability may arise.

7. Using generic certificates without job analysis

Fitness should be linked to actual duties.

8. Confusing HR labels with benefit entitlement rules

Employment status and disability compensation are not always the same inquiry.

XIX. Best Legal Interpretation of the Philippine Rule

A coherent reading of Philippine law yields the following principles:

Fitness-to-work classification is legally recognized, though not comprehensively codified in one statute.
Its legal basis is plural, drawn from labor law, OSH law, social legislation, disability law, mental health law, privacy law, and jurisprudence.
The medical conclusion is not identical to the employment consequence.
Restrictions should be job-specific and evidence-based.
Temporary unfitness generally supports leave, treatment, or reassessment, not immediate termination.
Permanent or serious disease may justify separation only under strict statutory conditions.
Public health authority certification is crucial where the Labor Code requires it.
Accommodation, reassignment, or modified duties should be considered where feasible.
Health information must be handled confidentially.
Courts scrutinize employer reliance on medical findings when livelihood is affected.

XX. A Practical Legal Taxonomy for Philippine Use

Although not fixed by one national law, the following framework is the most legally defensible in Philippine practice:

A. Fit to work

Can perform essential job functions safely.

B. Fit to work with temporary restrictions

Can work subject to short-term limitations and reevaluation.

C. Fit to work with permanent restrictions

Can continue working, but long-term modification or reassignment may be necessary.

D. Temporarily unfit to work

Should not presently work; reevaluation required.

E. Permanently unfit for the present position

Cannot safely perform the current role; reassignment should be evaluated if possible.

F. Permanently unfit for any gainful work of similar nature

A much stronger conclusion, usually relevant to disability and separation questions; should not be used loosely.

This functional framework is better than simplistic binary labels because it aligns medical assessment with labor-law consequences.

XXI. Model Legal Questions to Ask in Any Fitness-to-Work Case

To determine the legal effect of a classification in the Philippines, one should ask:

What exact work is the employee hired to do?
What tasks are essential, and what are incidental?
What illness or impairment exists, and how severe is it?
Is the finding temporary or permanent?
Is the worker totally unable, or restricted only in some tasks?
Is the risk to self or others real and medically supported?
Is there a treating physician opinion?
Is there a competent public health certification if dismissal for disease is being considered?
Can accommodation, reassignment, or modified duty solve the problem?
Were privacy and due process observed?
Are SSS, ECC, insurance, CBA, or disability-plan benefits implicated?
Is this a general employment case or a specialized sector case such as seafaring?

That is the proper Philippine legal method.

XXII. Bottom Line

The legal basis for fitness-to-work classifications in the Philippines is not found in one single statute, but in an interlocking framework of:

constitutional protection to labor and health
Labor Code rules on disease and security of tenure
occupational safety and health law
disability and anti-discrimination principles
mental health protections
data privacy law
SSS and ECC benefit systems
sector-specific rules, especially for seafarers
Supreme Court jurisprudence on medical evidence, due process, and lawful termination

The most important legal truths are these:

A medical fitness classification is evidence, not automatic legal destiny.
“Unfit to work” does not by itself equal lawful dismissal.
Temporary incapacity and permanent incapacity are legally different.
Disease termination is strictly regulated and cannot rest on casual internal certification alone.
Restricted fitness often triggers accommodation or reassignment analysis, not exclusion.
Privacy, dignity, and due process are integral to any lawful fitness-to-work system.

In Philippine law, the controlling principle is simple: medical necessity may justify workplace action, but only within the boundaries of labor rights, public health requirements, procedural fairness, and human dignity.
