Employers are often required to apply discipline consistently. This principle, commonly referred to as the parity principle, is an important element of fairness.
However, consistency is not absolute. There are circumstances in which deviation from past disciplinary outcomes is justified, particularly when misconduct is serious or distinguishable.
The Facts
In Buthelezi and Others v Rand Water – Zuikerbosch Water and Others, employees colluded with their supervisor to falsify timesheets and claim overtime that was not worked. This dishonest conduct resulted in financial losses exceeding R53 000.00.
Although the employees pleaded guilty, they challenged their dismissal on the basis of inconsistency, arguing that other employees had previously received final written warnings for similar misconduct.
Legal Framework
The courts recognise two forms of inconsistency:
- Historical inconsistency: Whether the employer has treated similar misconduct differently in the past.
- Contemporaneous inconsistency: Whether employees involved in the same misconduct are treated differently.
To succeed, an inconsistency claim must establish:
- A valid comparator (similarly situated employee).
- Employer knowledge of the comparator misconduct (subjective element).
- Material similarity in circumstances (objective element).
Differences in personal circumstances, severity, or surrounding facts may justify different outcomes.
Case Law
The Commissioner found that the Applicants’ misconduct was distinguishable and significantly more serious than that of their comparators.
Key findings included:
- The misconduct was deliberate, coordinated, and fraudulent.
- It was described as “well-orchestrated, planned and deviously thought out”.
- It had a clear financial and operational impact on the employer.
The courts have repeatedly cautioned against the rigid application of the parity principle.
In ABSA Bank Ltd v Naidu and Others, the Labour Appeal Court of South Africa confirmed that consistency must be applied with caution.
Similarly, in SACCAWU and Others v Irvin and Johnson (Pty) Ltd, the Court emphasised that fairness is ultimately a value judgment and that employees should not benefit from incorrect or lenient past decisions unless those decisions were capricious or discriminatory.
In Hulett Aluminium (Pty) Ltd v Bargaining Council for the Metal Industry and Others, the Court further held that the gravity of misconduct must be central when applying the parity principle.
Application to Employers
This case reinforces that consistency is only one factor in determining fairness. Employers are not required to repeat past mistakes or apply leniency where serious misconduct is involved.
Where dishonesty is deliberate and undermines the trust relationship, dismissal will often be justified, even if previous cases were treated differently. The key is whether the employer can objectively distinguish the circumstances and justify the outcome.
Practical Steps for Employers
- Apply discipline consistently, but not blindly:
Consistency is important, but must be balanced with fairness and context.
- Assess the seriousness of misconduct:
Deliberate and dishonest conduct will justify stricter sanctions.
- Identify valid comparators:
Ensure that any comparison is based on truly similar circumstances.
- Document distinguishing factors:
Record why a particular case warrants a different outcome.
- Protect the trust relationship:
Where trust is irreparably broken, dismissal is often appropriate.
Key Takeaways / Conclusion
The parity principle is a safeguard against unfair discrimination, not a shield against accountability.
Employers are not bound to treat all misconduct identically, particularly where the seriousness and context differ. In cases of deliberate dishonesty, consistency gives way to the more fundamental question: Can the employment relationship continue?
Where the answer is no, dismissal will remain a fair and reasonable outcome.
