A positive drug or alcohol test is not always the end of an employment relationship. In many cases — particularly where the employee has demonstrated a willingness to address the issue — the organisation will manage a return-to-work process. Getting this process right is essential for the safety of the workplace, the wellbeing of the employee, and the legal defensibility of the decisions made along the way.

This playbook provides HR professionals with a practical framework for managing return-to-work after a positive test result in Australian workplaces.

Establishing Conditions for Return

Before an employee returns to their role after a positive test, several conditions must be met. These should be documented in a formal return-to-work agreement signed by the employee, their manager, and a HR representative.

Typical conditions include:

• Clearance from a medical professional — an occupational health practitioner or the employee’s treating doctor should confirm that the employee is fit to return to their substantive role, including any safety-sensitive duties.
• Completion of an initial EAP engagement — the employee should have attended at least one session with the Employee Assistance Program and, where appropriate, committed to an ongoing counselling or treatment plan.
• A negative return-to-work test — before resuming duties, the employee should return a negative drug and alcohol test result. This confirms that they are not currently impaired and provides a documented baseline.
• Acknowledgement of conditions — the employee must sign the return-to-work agreement, confirming they understand the monitoring framework, follow-up testing schedule, and consequences of any further positive result.

The conditions should be proportionate to the circumstances. An employee who returned a low-level positive for cannabis may require a different level of monitoring than one who tested positive for methamphetamine in a safety-critical role.

Designing the Monitoring Framework

A return-to-work monitoring framework provides structure and accountability for both the employee and the organisation. It should be tailored to the individual circumstances but typically includes:

• Duration — most return-to-work monitoring periods run for six to twelve months, though this may vary based on the substance involved, the employee’s role, and the recommendations of the treating professional.
• Reporting requirements — the employee may be required to provide periodic confirmation of ongoing engagement with their treatment or counselling provider.
• Regular check-ins — scheduled meetings between the employee and their manager or HR representative to discuss progress, address any concerns, and review the plan.
• Performance monitoring — any performance issues that may be related to the underlying substance issue should be monitored and addressed through the standard performance management process.

Follow-Up Testing Schedule

Follow-up testing is a critical component of the return-to-work process. It serves both as a deterrent and as a mechanism to identify any relapse early. The testing schedule should be:

• More frequent initially — testing in the first three months is typically more frequent (e.g., monthly or fortnightly) before tapering to quarterly for the remainder of the monitoring period.
• Unannounced — follow-up tests should be conducted without prior notice to the employee. Scheduled, predictable tests significantly reduce their deterrent value.
• Documented — every follow-up test must be recorded, including the date, time, result, and the name of the person who conducted the test. This documentation is essential for demonstrating compliance and for any subsequent disciplinary proceedings if the employee returns a further positive result.
• In addition to random testing — follow-up testing is separate from and additional to the organisation’s regular random testing program. The employee remains in the random selection pool as normal.

The specific frequency and duration of follow-up testing should be guided by the recommendations of the occupational health professional, the nature of the substance involved, and the risk level of the employee’s role.

EAP Engagement Verification

The return-to-work agreement should specify that the employee is required to engage with the EAP or an equivalent treatment provider for the duration of the monitoring period. HR’s role is to verify that this engagement is occurring without intruding into the content of the sessions.

This is managed by:

• Requesting periodic confirmation from the EAP provider that the employee has attended their scheduled sessions (attendance only — not session content).
• Requiring the employee to provide a letter from their treating professional at specified intervals confirming ongoing engagement and fitness for duty.
• Following up promptly if attendance lapses and treating non-engagement as a breach of the return-to-work agreement.

Documentation Requirements

Thorough documentation is non-negotiable. If the return-to-work process ultimately fails and disciplinary action (including termination) is required, the documentation will form the basis of the organisation’s defence in any unfair dismissal claim.

Key documents include:

• The original positive test result and chain of custody documentation.
• Records of any disciplinary meeting held in response to the positive result.
• The return-to-work agreement, signed by all parties.
• All follow-up test results.
• EAP attendance confirmations.
• Notes from regular check-in meetings.
• Any correspondence between the employee, HR, and management regarding the process.
• Medical clearance documentation.

Store these records securely with restricted access, separate from the employee’s general personnel file.

Managing Team Dynamics

An employee’s return to work after a positive test can be difficult for their colleagues. Team members may have concerns about safety, may feel the process is too lenient or too harsh, or may simply be curious about what happened.

HR can manage these dynamics by:

• Maintaining confidentiality — colleagues should not be informed about the specific circumstances of the employee’s absence or the reason for any modified duties. A neutral explanation such as “returning from a period of leave” is sufficient.
• Briefing the direct supervisor — the supervisor needs enough information to manage the return effectively, including any modified duties or restrictions, but should not be given the specific test result or substance involved.
• Addressing team concerns — if team members raise safety concerns, these should be taken seriously and addressed by confirming that the organisation has followed its policies and that the employee has been cleared to return. Specific details should not be shared.
• Monitoring for bullying or exclusion — employees returning after a positive test may be vulnerable to workplace bullying or social exclusion. HR should be alert to this and intervene if it occurs.

Defining Success Criteria

The return-to-work monitoring period should have clear criteria for successful completion. This provides the employee with a tangible goal and gives the organisation a defined endpoint for the heightened oversight.

Success criteria typically include:

• No further positive test results during the monitoring period.
• Consistent engagement with the EAP or treatment provider.
• Satisfactory work performance throughout the monitoring period.
• No safety incidents attributable to impairment.
• Compliance with all conditions in the return-to-work agreement.

Upon successful completion, the employee should be formally notified that the monitoring period has concluded and that they are no longer subject to the enhanced conditions. This closure is important — it signals that the matter is resolved and allows the employee to move forward.

Managing return-to-work effectively requires consistent processes, secure documentation, and the ability to track follow-up testing schedules without relying on memory or spreadsheets.
