Human resources professionals occupy a unique and often challenging position within workplace drug and alcohol testing programs. They are simultaneously the architects of policy, the guardians of compliance, the advocates for employee wellbeing, and the mediators when difficult situations arise. Getting this balance right is essential — not only for legal defensibility, but for maintaining the trust and engagement of your workforce.

This article explores how HR professionals can fulfil their role as policy owners while navigating the deeply human dimensions of drug and alcohol testing in Australian workplaces.

HR as the Policy Owner

In most organisations, HR is responsible for drafting, implementing, and maintaining the drug and alcohol policy. This is not a task that can be delegated to safety departments alone or outsourced entirely to legal counsel. While both play important supporting roles, HR must own the policy because it intersects directly with employment conditions, workplace culture, and employee relations.

As policy owner, HR is responsible for ensuring that the document:

• Reflects current legislation — including the Work Health and Safety Act 2011, the Fair Work Act 2009, applicable state privacy legislation, and anti-discrimination laws.
• Is practically enforceable — policies that look impressive on paper but cannot be consistently applied create more risk than having no policy at all.
• Has been subject to consultation — genuine consultation with employees, health and safety representatives, and unions (where applicable) is both a legal requirement in many jurisdictions and a practical necessity for buy-in.
• Is reviewed regularly — annual reviews should be scheduled, with ad hoc reviews triggered by legislative changes, significant incidents, or shifts in workforce composition.

HR must also ensure that the policy is accessible. A document buried in a shared drive that no one can find is, for all practical purposes, a document that does not exist. Every employee should know where to find the policy, and new starters should receive it as part of their induction.

Balancing Compliance with Employee Relations

One of the most difficult aspects of HR’s role in testing programs is maintaining the balance between strict compliance and positive employee relations. A policy that is enforced without empathy can erode trust and create an adversarial culture. Conversely, a policy that is applied inconsistently or softened to avoid difficult conversations exposes the organisation to significant legal and safety risk.

The key is procedural fairness. Every employee who is subject to testing — whether random, for-cause, or post-incident — must be treated consistently and in accordance with the documented process. This means:

• Following the same procedures every time, regardless of the individual’s seniority, tenure, or personal circumstances.
• Providing clear explanations of the process at each stage.
• Allowing employees to have a support person present during formal discussions about results.
• Documenting every step, from selection through to outcome.

HR professionals must resist the temptation to make informal exceptions. A manager who says, “Let’s not test Dave this time — he’s going through a tough patch,” is creating a precedent that undermines the entire program. The correct approach is to apply the process fairly and address personal circumstances through appropriate support mechanisms.

Confidentiality Obligations

Drug and alcohol test results are among the most sensitive categories of employee information. HR has a duty to ensure that results are handled with the highest level of confidentiality, consistent with the Australian Privacy Principles and any applicable state or territory health records legislation.

In practice, this means:

• Restricting access — only those with a legitimate need to know should have access to individual test results. This typically includes the HR manager, the employee’s direct supervisor (to the extent necessary for fitness-for-duty decisions), and senior management where disciplinary action is being considered.
• Secure storage — results must be stored in a system with appropriate access controls. Paper records should be kept in locked storage, and digital records should be in a system with role-based permissions.
• Communication protocols — results should never be discussed in open-plan offices, communicated via unsecured email, or shared with colleagues who do not have a need to know.
• Retention and disposal — your policy should specify how long records are retained and how they are securely disposed of when that period expires.

A breach of confidentiality around test results can destroy trust in the program, expose the organisation to privacy complaints, and cause significant personal harm to the employee concerned.

Managing Disclosures

When an employee voluntarily discloses a substance issue — whether prompted by an upcoming test or of their own accord — HR’s response sets the tone for the entire organisation’s relationship with the testing program.

A disclosure should be received with professionalism and without judgement. The employee should be thanked for coming forward, assured that the conversation is confidential (within the limits of safety obligations), and provided with immediate information about available support, including the Employee Assistance Program.

However, a disclosure does not suspend the organisation’s safety obligations. If the employee is in a safety-sensitive role and may currently be impaired, HR must work with operations to ensure they are not performing duties that could put themselves or others at risk. This is not punitive — it is a duty of care.

HR should also be aware that in some circumstances, a voluntary disclosure before a scheduled test may have implications for how any subsequent positive result is treated in disciplinary proceedings. Legal advice should be sought on a case-by-case basis.

Working with Safety and Operations

Drug and alcohol testing does not exist in a vacuum. HR must work closely with safety, operations, and site management to ensure the program is implemented effectively. This collaboration includes:

• Selection logistics — working with shift supervisors to schedule testing at times that minimise operational disruption while still covering all shifts equitably.
• Training — ensuring supervisors understand their role in the testing process, particularly around reasonable suspicion observations and immediate response to positive results.
• Incident response — coordinating with safety teams on post-incident testing protocols, ensuring that testing is conducted promptly and in accordance with policy.
• Data sharing — providing aggregated, de-identified testing data to safety committees and management for trend analysis, without compromising individual confidentiality.

The most effective programs are those where HR, safety, and operations function as a coordinated team rather than operating in silos.

Being the Mediator

When a positive result occurs, HR often finds itself mediating between competing interests. Management may want swift disciplinary action. The employee may be seeking support and a second chance. The union may be advocating for procedural fairness. Legal counsel may be advising caution.

HR’s role is to ensure that the process outlined in the policy is followed precisely, that all parties are heard, and that decisions are documented with clear reasoning. This mediating function requires:

• Strong knowledge of the policy and relevant legislation.
• The ability to remain impartial while being empathetic.
• Clear communication skills to manage expectations on all sides.
• The confidence to push back against pressure to deviate from established procedures.

The best HR professionals in this space understand that their role is not to be popular — it is to be fair, consistent, and transparent.

Building a Trusted Program

Ultimately, the success of a drug and alcohol testing program depends on whether employees trust it. Trust is built through consistency, confidentiality, fairness, and visible support for those who need help. HR is the custodian of that trust.

Investing in the right systems and processes makes HR’s role significantly more manageable. When selection is genuinely random, records are secure, and reporting is automated, HR can focus less on administration and more on the human dimensions of the program.
