Right to individual defence: Court reinstates 19 workers after unfair strike dismissalIn a significant judgment delivered on 28 August 2025, the Labour Court of South Africa reviewed and overturned the dismissal of 19 employees of Plusnet Geotex, a division of Master Plastics Ltd. ![]() Image source: Freepik The case, brought by the Southern African Clothing and Textile Workers’ Union, centred on whether the dismissals were substantively and procedurally fair, particularly in light of the legal doctrine of common purpose and the handling of hearsay evidence. This ruling offers critical insights into how employers must approach disciplinary action during strikes and how arbitrators must apply legal principles with precision and fairness. Legal implicationsMisapplication of common purposeThe central legal issue was the arbitrator’s reliance on the doctrine of common purpose to justify the dismissal of 50 employees, including 40 who denied any involvement in misconduct. As reaffirmed by the Labour Court, the doctrine requires the following elements:
The arbitrator failed to apply these elements rigorously. Instead, he relied on inferential reasoning and assumed guilt based on mere participation in a protected strike and failure to “disassociate” from misconduct. The court found this approach legally untenable, as it blurred the line between lawful strike participation and criminal complicity. The court emphasised that presence alone or association by union membership does not satisfy the legal threshold for common purpose. This sets a precedent that employers must prove individual culpability, not collective guilt. Procedural unfairness
Hearsay evidenceThe arbitrator provisionally admitted hearsay evidence from both parties but failed to:
Hearsay may be admitted if:
The court found that while the hearsay evidence was not entirely inadmissible, the arbitrator’s mismanagement of its admission contributed to an unreasonable outcome. Inconsistency in disciplineThe employer dismissed 50 employees but spared 15 others who participated in the same strike. This raised serious concerns about inconsistent application of discipline, which the arbitrator failed to address. The parity principle requires that similarly situated employees be treated equally. Disparate treatment must be justified by clear evidence. The court found that the employer’s failure to explain why some employees were spared undermined the fairness of the dismissals.

Final thoughtsThis judgment is a powerful reminder that fairness in labour relations is not just about following procedure, it is about applying the law with integrity and precision. The court’s decision to reinstate 19 employees with 36 months’ back pay underscores the importance of individual justice, even within collective disputes. Employers must tread carefully when dealing with strike-related misconduct, ensuring that each case is assessed on its own merits. Arbitrators, too, must be vigilant in applying legal principles correctly and transparently. In the end, justice prevailed, not through assumption but through evidence.
