Zero-Tolerance Drug Policies and Dismissal: What Employers Can Learn from MHE Electronics v Toffie

<p>A recent Labour Court judgment gives employers useful guidance on when a <strong>zero-tolerance drug policy</strong> can support dismissal and what needs to be considered when an employee tests positive for drugs at work.</p><p>In <em>MHE Electronics (Pty) Ltd v Toffie and Others [2026] 5 BLLR 512 (LC)</em>, the Labour Court considered the fairness of dismissing two employees who tested positive for narcotics during random workplace drug testing.</p><p>The case shows that having a zero-tolerance policy is not enough on its own. Employers must also be able to show that the policy was properly applied, the testing was reliable, and the circumstances justified the sanction.</p><h2>The Facts</h2><p>Two employees were dismissed after testing positive for narcotics in breach of the company's zero-tolerance drug policy.</p><p>The first employee was a <strong>laser and engraving machine operator</strong> who tested positive for THC, cocaine and amphetamines. The machine produced a flame and required close concentration, creating a clear safety concern if the employee was impaired.</p><p>The second employee was the company's <strong>primary forklift driver</strong>. He tested positive for heroin/morphine and amphetamines. His duties included lifting loads of up to 500kg, making impairment a serious safety risk to both himself and others.</p><p>A third employee also tested positive for heroin/morphine and THC and was dismissed. However, he did not refer a dispute, so his case was not considered by the Court.</p><p>At the disciplinary hearing, the laser operator <strong>pleaded guilty</strong>. The forklift driver pleaded not guilty and disputed the test results, saying that a doctor had told him the results did not indicate the use of an intoxicating narcotic. The doctor, however, was not called to give evidence.</p><h2>What Happened at Arbitration?</h2><p>Both employees referred unfair dismissal disputes to the bargaining council.</p><p>They challenged the reliability of the drug tests and suggested that the results may have been mixed up.</p><p>The arbitrator found the dismissals unfair. The main concerns were that the employer had not sufficiently proven the accuracy of the test results, the person conducting the tests was allegedly not suitably qualified, and the policy had allegedly been applied inconsistently because another employee who tested positive only for THC had not been dismissed.</p><p>The employees were initially awarded reinstatement and backpay, which was later changed to compensation.</p><p>The employer then took the matter on review to the Labour Court.</p><h2>What Did the Labour Court Decide?</h2><p>The Labour Court set aside the arbitrator's award and found both dismissals to be <strong>substantively and procedurally fair</strong>.</p><p>Three parts of the Court's reasoning are particularly important for employers.</p><h3>1. A Guilty Plea Matters</h3><p>The laser operator had pleaded guilty at his disciplinary hearing.</p><p>The Court found that this was important evidence and that the arbitrator had not given the admission proper consideration.</p><p>An employee's plea and any admissions made during a disciplinary hearing can therefore become important evidence if the matter later goes to arbitration or review.</p><h3>2. Consistency Does Not Mean Treating Every Positive Test the Same</h3><p>The arbitrator considered the employer's decision not to dismiss an employee who tested positive only for THC to be inconsistent.</p><p>The Labour Court disagreed.</p><p>The Court recognised the difference between cannabis and substances such as <strong>cocaine, heroin and amphetamines</strong>, particularly given the legal position regarding private cannabis use.</p><p>This meant that employees who tested positive for different substances did not necessarily have to receive the same sanction.</p><p>The important point is that <strong>consistency means fair and rational treatment, not necessarily identical treatment in every case</strong>.</p><p>Employers should still be able to explain why different substances or circumstances resulted in different outcomes.</p><h3>3. Workplace Safety Matters</h3><p>The Court also looked at the nature of the employees' jobs.</p><p>Both employees worked in positions where impairment could put themselves and others at risk. The laser operator worked with machinery involving a flame, while the forklift driver operated equipment used to lift heavy loads.</p><p>The Court found that the employer's responsibility to provide a safe working environment had not been given enough weight.</p><p>This highlights why employers should consider the <strong>actual risks associated with an employee's position</strong> when deciding on an appropriate sanction.</p><h2>What This Means for Employers</h2><h3>Zero-Tolerance Policies Are Stronger in Safety-Critical Roles</h3><p>A zero-tolerance policy is easier to defend where impairment could reasonably put employees, customers, equipment or the public at risk.</p><p>This is particularly relevant to drivers, forklift operators, machine operators and other employees working in safety-sensitive positions.</p><p>The policy must also be clearly communicated and consistently applied.</p><h3>A Guilty Plea Can Matter Later</h3><p>An employee who admits to misconduct during a disciplinary hearing should understand that the admission may still be relevant if the matter later proceeds to arbitration.</p><p>Employers should ensure that the employee's plea and any admissions are properly recorded.</p><h3>Different Substances May Justify Different Treatment</h3><p>A positive drug test does not automatically make every case the same.</p><p>The substance involved, the employee's duties, the potential safety risk, the circumstances of the test and the company's policy can all be relevant when deciding on the appropriate sanction.</p><p>Where employees are treated differently, the employer should be able to explain the <strong>reason for the difference</strong>.</p><h3>The Testing Process Must Be Defensible</h3><p>Employers need to be able to show that drug testing was conducted properly and that the results can be relied upon.</p><p>The person conducting the test, the testing procedure, handling of the sample and recording of the results can all become important if an employee challenges the outcome.</p><p>A policy is only as strong as the process used to enforce it.</p><h2>Conclusion</h2><p><em>MHE Electronics v Toffie</em> is a useful reminder that having a zero-tolerance drug policy does not automatically make a dismissal fair.</p><p>Employers still need to consider <strong>the reliability of the testing, the circumstances of the employee, the application of the policy, the employee's duties and the safety risks involved</strong>.</p><p>Where these factors are properly considered and supported by evidence, a zero-tolerance approach can withstand scrutiny, particularly where the employee works in a safety-critical role.</p><p><em>Source: Jefferson, M.
