Warehouse Employee Positive Drug Test: PH Termination Rules

A random drug test comes back positive for a forklift operator, picker or checker, and the warehouse manager wants the employee off the floor and out of the company by Friday. A positive drug test is a recognized ground for suspension or termination in the Philippines, but it is also one of the dismissal cases employers lose most often, usually because the test itself does not hold up.

This guide, for warehouse managers, logistics operations heads and HR officers, covers when a positive result supports dismissal, what the screening and confirmatory test must look like, how the company drug policy decides between rehabilitation and termination, and how to run due process for a warehouse employee.

Direct Answer

A warehouse employee who tests positive for dangerous drugs may be suspended or dismissed under Section 36(d) of Republic Act No. 9165, subject to Article 297 [282] of the Labor Code.^[3]^[1] The result must come from a DOH-accredited laboratory and include both a screening and a confirmatory test.^[4]^[7] The penalty must follow a clear, published company drug policy and be proportionate, and the twin-notice procedure, with at least five calendar days to answer, must be observed.^[2]^[9]

Key Takeaways

Random drug testing of private employees is valid when it is part of the company’s work rules. The Supreme Court upheld Section 36(d) in Social Justice Society v. Dangerous Drugs Board.^[6]
No confirmatory test, no valid dismissal. In Nacague, a screening-only result from a clinic not shown to be accredited could not support termination.^[7]
The test chain must be clean. In Plantation Bay, confirmatory results timestamped before the samples arrived sank the dismissals of the workers who challenged them.^[8]
D.O. 53-03 gives an employee diagnosed with drug dependence for the first time the option of referral to treatment. Your written policy must say what happens to a first positive.^[4]
Drug use inside the warehouse during working hours is serious misconduct under Article 297(a).^[10]
Penalties must match the policy and the offense. In Mirant v. Caro, dismissal under a vague “unjustified refusal” rule was struck down.^[9]
Test results are confidential and may be shared only on a need-to-know basis.^[4]

What Makes a Warehouse Drug Test Valid

Most lost drug-test dismissals are lost on the test, not the law. Check the result against four requirements.

1. A DOH-accredited laboratory

Section 36 of RA 9165 allows authorized drug testing only by government forensic laboratories or drug testing laboratories accredited and monitored by the DOH.^[3] D.O. 53-03 repeats the rule for private workplaces.^[4] In Nacague, the employer never proved the clinic was accredited and did not deny the employee’s claim that it was not. That alone weakened the case.^[7] Keep a copy of the laboratory’s DOH accreditation in the case file.

2. Screening plus confirmatory test

A screening test only gives a presumptive positive. The confirmatory test, using a different and more specific method, validates it.^[3] D.O. 53-03 requires both, and requires that the employee be told the results.^[4] The Supreme Court reinstated the Labor Arbiter’s illegal dismissal ruling in Nacague because the employer “did not confirm the positive result of the screening test with a confirmatory test.”^[7]

3. A clean chain of custody

In Plantation Bay Resort and Spa v. Dubrico, a resort tested about 122 employees and dismissed those found positive. The confirmatory results were timestamped about an hour before the laboratory logged receipt of the samples. The Court asked how the presence of shabu could be confirmed before the screening results were out, and held the dismissals illegal. It also said the employer is responsible for making sure the tests are properly administered.^[8] For a warehouse running a site-wide random test across shifts, that means one collection log per batch, sealed specimens, signed custody forms and laboratory receipt times you have actually checked.

4. A test authorized by your work rules

Section 36(d) ties random testing of private employees to “the company’s work rules and regulations,” with the cost borne by the employer.^[3] The Court in Social Justice Society treated that link to company rules, the random selection and the confidentiality safeguards as what makes testing reasonable.^[6] D.O. 53-03 also allows additional tests after workplace accidents, including near misses, and on clinical findings or an Assessment Team recommendation.^[4] That matters in a warehouse: a forklift collision with racking or a dropped pallet load is exactly the post-incident trigger your policy should name.

Rehabilitation or Termination: What Your Policy Decides

Many HR officers assume D.O. 53-03 forbids dismissal for a first positive test. It does not say that. It says two things that sit side by side.

An employee found positive “shall be dealt with administratively” under the Labor Code and RA 9165.^[4] RA 9165 itself makes a positive result a ground for suspension or termination.^[3]
Referral to a DOH-accredited treatment and rehabilitation center is an option given to employees diagnosed with drug dependence for the first time, and to employees who come forward for help. Repeated use after ample opportunity for treatment is dealt with under the penalties of RA 9165.^[4]

The result is that your written drug-free workplace policy does the deciding. If it says a first confirmed positive leads to assessment and referral, you must follow it. If it says a first confirmed positive in a safety-sensitive role leads to dismissal, that penalty is enforceable only if the policy was published, acknowledged and applied consistently.

Why vague rules lose

In Mirant (Philippines) Corp. v. Caro, the drug policy made “unjustified refusal” to take a random test a first-offense dismissal, but did not define the phrase. A ten-year supervisor who missed his test after a family emergency was dismissed. The Court held the policy unclear, the penalty disproportionate, and resolved the doubt in favor of the employee under Article 4 of the Labor Code.^[9] Warehouses should define, in writing, what counts as refusal, tampering, a no-show and a dilute sample, and what each one costs.

Use versus possession or selling

A positive test proves use, not dealing. If a picker is caught with sachets in a locker or selling to co-workers on the dock, charge that conduct separately as serious misconduct and refer the criminal side to the authorities.^[4]^[1] In Bughaw v. Treasure Island Industrial Corp., the Court held that drug use inside company premises during working hours is serious misconduct, noting that an employee under the influence of drugs cannot possibly continue doing his duties.^[10]

When the issue is health, not discipline

If the Assessment Team finds drug dependence and you choose not to discipline, the employee may still be unfit for safety-sensitive equipment. Moving the employee off forklift duty during treatment is a separate decision. Ending employment on medical grounds falls under Article 299 [284], with its own certification and separation pay rules; see termination due to disease.^[1]

Warehouse Evidence That Holds Up

The employer carries the burden of proving a valid cause with substantial evidence.^[1]^[8] Build the file around the test, then add what the warehouse itself recorded.

Evidence	Source in a warehouse	What it proves
Screening and confirmatory test results	DOH-accredited laboratory	Presence of a dangerous drug, validated by a second method
Laboratory accreditation	Laboratory or DOH listing	Test was done by an authorized center
Selection list and collection log	HR and Assessment Team	Random selection under the policy; no singling out
Chain-of-custody forms	Collection officer and laboratory	Specimen identity and timing, the gap that sank Plantation Bay
Signed policy acknowledgment	201 file, onboarding records	Employee knew the rule and the penalty
Equipment authorization	Forklift or reach-truck permit, training records	Safety-sensitive role, relevant to proportionality
Incident or near-miss report	Safety officer, WMS or CCTV	Reason for a post-incident test and risk created
Supervisor observation report	Shift lead	Signs of impairment on the floor, if any

Keep the file sealed and limited to the people deciding the case. D.O. 53-03 requires the employer to keep all drug test information confidential, subject to narrow exceptions.^[4]

Taking the Employee Off the Floor

A warehouse cannot leave a confirmed-positive forklift operator on equipment while the case runs. You have two lawful options.

Reassignment to non-equipment work, such as cycle counting or documentation, at the same pay.
Preventive suspension without pay, for up to 30 days, when the employee’s continued presence poses a serious and imminent threat to the life or property of the employer or co-workers. Beyond 30 days, you must reinstate or pay wages during any extension; a prolonged suspension can become constructive dismissal.^[12]

Document why the threat is real for this role, such as a counterbalance forklift in an aisle shared with pickers. More detail is in the preventive suspension guide.

Step-by-Step Procedure

Confirm the result. Do not act on a screening result. Wait for the confirmatory test from the accredited laboratory and tell the employee the result.^[4]
Remove the employee from equipment through reassignment or a written preventive suspension order stating the threat.^[12]
Convene the Assessment Team under your drug-free workplace policy to evaluate the result and recommend the level of care and administrative action.^[4]
Check the policy. Identify the exact provision violated and the penalty it sets for a first or repeat positive. If the policy calls for referral, refer.
Issue the Notice to Explain. State the test date, laboratory, confirmatory result, policy provision and the Article 297(a) ground. Give at least five calendar days to answer.^[2]^[11] Use the Notice to Explain guide for wording.
Hold a conference if the employee asks for one, disputes the test, or raises a prescription medicine explanation. Let the employee see the results and custody records.^[2]
Decide in writing. The notice of decision should address the employee’s explanation, the test validity and why the penalty is proportionate to the role and record.^[2]^[9] Review the twin-notice rule before serving it.
Serve and document the decision personally or by registered mail and keep proof of receipt. In Bughaw, missing proof of service of the second notice cost the employer ₱30,000 in nominal damages.^[10]

Common Employer Mistakes

Dismissing on a rapid test. A cassette test at the guardhouse is a screening result only.^[3]^[7]
Using an unaccredited clinic because it already handles annual physicals.^[7]
Not checking laboratory timestamps on batch tests after a site-wide random draw.^[8]
Testing only the agency-supplied pickers or one disliked shift, which undermines the randomness the law relies on.^[6]
Skipping the policy’s referral step for a first positive when the policy promises one.^[4]
Vague penalty wording such as “refusal” or “non-compliance” without definitions.^[9]
Leaking results to team leads who do not need to know.^[4]

Frequently Asked Questions

Can a warehouse employee be dismissed for a first positive drug test?

Yes, if your published drug-free workplace policy sets dismissal for a first confirmed positive and the test is valid. RA 9165 makes a positive result a ground for suspension or termination. But if the policy provides assessment and referral for first-time drug dependence, you must follow it. Proportionality to the role, such as forklift operation, and the employee’s record still matter.

Is a rapid drug test at the warehouse gate enough?

No. A rapid or screening test only shows a presumptive positive. The law requires a confirmatory test by a DOH-accredited laboratory using a different, more specific method. The Supreme Court ruled a dismissal illegal in Nacague v. Sulpicio Lines because the employer relied on a screening result that was never confirmed.

Can we drug test a forklift operator after an accident?

Yes, if your policy provides for it. D.O. 53-03 allows additional drug tests after workplace accidents, including near misses, and on clinical findings or an Assessment Team recommendation. Name these triggers in your written policy, use an accredited laboratory and keep the same custody and confidentiality safeguards as random testing. The employer pays for the test.

What if the employee says the result came from prescription medicine?

Treat it as a defense that must be evaluated, not ignored. Ask for the prescription and the prescribing doctor’s details, refer the question to the Assessment Team and the laboratory, and record the finding in the notice of decision. A dismissal that brushes aside a documented explanation weakens the employer’s burden of proving a valid cause.

Is an employee dismissed for drug use entitled to separation pay?

Generally no. Separation pay is not due when dismissal is for a just cause such as serious misconduct. It becomes relevant if the dismissal is later ruled illegal, as in Nacague, where separation pay was awarded in lieu of reinstatement, or if employment ends under Article 299 on medical grounds instead of discipline.

Can we tell the client or other warehouse staff why the employee was removed?

Only on a need-to-know basis. D.O. 53-03 requires employers to keep drug test information confidential, with narrow exceptions such as legal requirements, overriding public health and safety concerns, or the employee’s written authorization. Tell the client or team that the employee is off the account pending an administrative matter, without naming the test.

What to Do Next

Pull the laboratory’s accreditation and the confirmatory result before drafting anything.
Read your drug-free workplace policy and confirm whether it calls for referral or discipline on a first positive. If the wording is unclear, fix it for future cases, not this one. The workplace drug testing guide covers policy content.
Compare with related cases in your file using serious misconduct dismissal rules and the serious misconduct glossary entry.
If the employee files at DOLE, bring the full file to the conference; see the SEnA filing process.^[5]

For the wider sector, see the factory and warehouse workers hub and the guide on workers reporting to site intoxicated.

If you are the employee who tested positive

Ask for copies of the screening and confirmatory results, the laboratory’s name and its DOH accreditation. D.O. 53-03 requires both tests, an accredited center and that you be told the results.^[4]
Answer the Notice to Explain in writing within the period it gives (at least five calendar days). Raise any prescription medicine, a missing confirmatory test, or gaps in the collection and custody records, and ask for a conference if you dispute the test.^[2][11]
Check the company policy for a referral or treatment option. D.O. 53-03 gives that option to employees diagnosed with drug dependence for the first time.^[4]
If you are dismissed and believe it was illegal, start with a Request for Assistance under SEnA at the DOLE office, which is the mandatory conciliation step; if it does not settle, the illegal dismissal complaint goes to the NLRC Labor Arbiter.^[5] Bring the notices, your written answer, the test results, your contract and payslips.
Mind the deadline. The Supreme Court has held that an illegal dismissal complaint must be filed within four years under Article 1146 of the Civil Code (Callanta v. Carnation Philippines, G.R. No. L-70615, October 28, 1986). Money claims arising from employment prescribe in three years under Article 306 [291] of the Labor Code.^[1]
