Employers are encouraged, and in many cases required, to maintain a drug-free workplace, which can include drug testing of employees under the Comprehensive Dangerous Drugs Act and its implementing rules. However, testing must follow safeguards: it should be done by an accredited testing center, a positive screening test must be confirmed by a confirmatory test before any adverse action, and results must be kept confidential. A single confirmed positive drug test may be a valid ground for dismissal, but the employer must still observe due process (notice and hearing) and follow its drug-free workplace policy. Employees also have rights to privacy and against being singled out arbitrarily, and refusal or a positive result should be handled through the proper procedure, not summary action.
Many workers are asked to undergo drug testing at work. Employers can require it — but there are safeguards that protect employees from arbitrary or careless action.
The Drug-Free Workplace Policy
Under the Comprehensive Dangerous Drugs Act and its implementing rules, employers are encouraged (and in many workplaces required) to maintain a drug-free workplace, which may include an employee assistance program and drug testing. Larger workplaces are expected to have a written drug-free policy.
The Testing Safeguards
Drug testing must follow rules that protect accuracy and fairness:
- Testing should be done by an accredited drug testing center;
- A positive screening test must be confirmed by a confirmatory test before any adverse action — a single unconfirmed screen is not enough; and
- Results must be kept confidential — they cannot be freely disclosed.
A Confirmed Positive and Dismissal
A confirmed positive drug test may be a valid ground for dismissal (as serious misconduct or a violation of the drug-free policy). But the employer must still:
- Observe due process — the twin-notice rule and an opportunity to be heard; and
- Follow its own drug-free workplace policy and the applicable rules.
Summary dismissal on an unconfirmed result or without due process can be illegal dismissal.
Employee Rights
- Confidentiality of results;
- The right to a confirmatory test before adverse action;
- A degree of privacy and protection against being arbitrarily singled out; and
- Due process before any dismissal.
Balancing Interests
The law balances the employer's legitimate interest in a safe, drug-free workplace against the employee's rights to privacy, confidentiality, and due process. Testing is allowed — but it must be done properly.
Practical Takeaways
- Employers may conduct drug testing under a drug-free workplace policy;
- A positive screen must be confirmed by a confirmatory test, and results kept confidential;
- A confirmed positive can justify dismissal, but only with due process — summary action on an unconfirmed result can be illegal dismissal.
Frequently Asked Questions
Can my employer require a drug test? Yes. Under the drug-free workplace policy and the Comprehensive Dangerous Drugs Act, employers may conduct drug testing, ideally through an accredited testing center and following the required safeguards.
Is one positive drug test enough to be fired? A positive screening test must be confirmed by a confirmatory test before any adverse action. A confirmed positive may justify dismissal, but the employer must still observe due process and follow its drug-free policy.
Are drug test results confidential? Yes. Results must be kept confidential and cannot be freely disclosed. Confidentiality is one of the safeguards protecting employees.
Can I be dismissed immediately for a positive result? No. Summary dismissal on an unconfirmed result or without due process can be illegal dismissal. There must be a confirmatory test and observance of the twin-notice rule.
