How long does a written warning last? Progressive discipline and the expired-warning trap
7 min read
A retail employee is late for the third time in a year. The owner pulls the file and finds a final written warning for timekeeping, issued fourteen months ago. Third strike. He dismisses her at the hearing, confident the paper trail carries the decision.
At the CCMA, the arbitrator asks one question: how long was that final warning valid for? The company's own disciplinary code — a template downloaded years ago and never read — says twelve months. The warning lapsed two months before the latest incident. In the eyes of the process, this employee has a clean record, and she has just been dismissed for arriving late once. The dismissal is substantively unfair, and the award reflects it.
Nothing about the hearing was wrong. The notice was proper, the chairperson was impartial, the minutes were kept. The case was lost in the filing cabinet, months earlier, by a warning nobody was tracking.
Discipline is corrective, not punitive
The Code of Good Practice: Dismissal (GN 3470, GG 53294, 4 September 2025) is built on a simple premise: the purpose of discipline is to correct behaviour, not to punish it. Dismissal is the last resort, reserved for misconduct so serious that it makes a continued working relationship intolerable, or for conduct that persists after the employer has genuinely tried to correct it.
That second path is progressive discipline, and it is the route most small-business dismissals travel: a verbal warning, then a written warning, then a final written warning, then — only if the conduct continues — dismissal. Each step tells the employee, on the record, that the conduct is unacceptable and what happens next if it is repeated.
The sequence is not a legal conveyor belt you must ride from the bottom every time. Serious misconduct can justify starting at a final warning, and gross misconduct — theft, assault, gross dishonesty — can justify dismissal for a first offence, as we covered in the hearing when discussing sanction. But for the ordinary run of workplace problems — late-coming, absenteeism, poor timekeeping, minor insubordination — the CCMA expects to see correction attempted before dismissal is reached. An employer who jumps straight to dismissal for conduct that warranted a warning has imposed an unfair sanction, however fair the procedure was.
So how long is a warning valid?
Here is the part that surprises most employers: the Code does not say. There is no section of GN 3470, and no section of the Labour Relations Act, that fixes how long a verbal, written, or final warning remains in force.
Validity periods come from your own disciplinary code — and if you do not have one, from what is reasonable and consistently applied in your workplace. The convention that has hardened across South African workplaces, and that arbitrators will recognise, is:
| Warning type | Typical validity |
|---|---|
| Verbal warning | 3 months |
| Written warning | 6 months |
| Final written warning | 12 months |
Two things follow from the fact that these are your rules rather than statute.
First, the warning itself should state its expiry date. A warning that says "valid for six months from the date of issue" leaves no argument about when it lapsed. A warning that is silent invites the dispute — and an arbitrator resolving an ambiguity in a document the employer drafted will not resolve it in the employer's favour.
Second, whatever periods you adopt, you are held to them. If your code says final warnings last twelve months, you cannot rely on one in month fourteen because the conduct feels like part of a pattern. The retail owner above did not lose because twelve months is the law; he lost because twelve months was his rule.
The expired-warning trap
An expired warning is, for the purposes of escalating sanction, gone. The employee stands before the next hearing with a clean record, and the sanction must be what a clean record warrants — which for late-coming is a warning, not a dismissal.
This is the trap in its simplest form, and small businesses walk into it constantly, for an understandable reason: nobody is watching the dates. The warning is issued in the heat of one incident, filed, and never looked at again until the next incident — which may be six weeks later or sixteen months later. Whether the employer still has an escalation path depends entirely on which, and on the day of the new incident almost no owner knows the answer.
The discipline this demands is unglamorous: every warning needs an issue date, an expiry date, and someone — or something — tracking the gap between them. When a warning is approaching expiry and the conduct has not recurred, that is the system working: the correction took. When the conduct recurs inside the validity period, the live warning is what entitles you to escalate.
Like must be matched with like
A live warning escalates sanction only for related conduct. A final written warning for timekeeping does not put an employee one step from dismissal for a negligence offence. The logic of progressive discipline is that the employee was warned about specific conduct and repeated it anyway — a warning about conduct A says nothing about whether the employee was on notice for conduct B.
This does not mean offences must be identical. Persistent late-coming and unauthorised absence are close enough kin that most arbitrators will treat them as the same family of misconduct. But an employer stacking unrelated warnings to manufacture a "third strike" will find the stack dismantled at arbitration, charge by charge.
Consistency cuts the same way it did at the sanction stage of the hearing: if one employee's third timekeeping offence inside a warning's validity earned a final warning, another employee's comparable third offence cannot earn a dismissal without a reason an arbitrator will accept.
Issuing a warning that holds up
A warning only does its job if it would survive scrutiny months later, in a hearing where it is the foundation of a dismissal. That means:
- It is in writing — including the "verbal" warning, which should be recorded even if it is delivered in conversation. An undocumented verbal warning is, at the CCMA, a warning that did not happen.
- It states the conduct specifically. "Poor attitude" proves nothing. "Arrived 45 minutes late on 3 June 2026 without notifying a manager" is a fact the next hearing can rely on.
- It states the consequence of repetition — that further misconduct of this kind within the validity period may lead to a final warning or dismissal, as the case may be.
- It states the expiry date.
- The employee saw it. Ask the employee to sign acknowledging receipt — not agreement, just receipt. If they refuse, record the refusal with a witness. A warning the employee can plausibly claim never to have received is barely a warning at all.
- The employee had a chance to respond. A warning does not require a formal enquiry, but the employee should be heard before it is issued — the same corrective conversation the Code's "genuine dialogue" language contemplates, scaled down.
The practical checklist
Before relying on progressive discipline — and before any warning leaves your hands — confirm:
- Your disciplinary code states validity periods for each warning type, and the periods are applied consistently to everyone.
- Every warning records the offence, the date, the consequence of repetition, and its expiry date, and the employee's receipt is acknowledged or the refusal witnessed.
- You know, today, which warnings are live across your staff — not which warnings exist in the files.
- Escalation relies only on live warnings for related conduct. An expired warning, or a live one for an unrelated offence, resets the employee to a clean record for sanction purposes.
- The sanction at each step matches a clean-record employee's sanction when no live warning applies — however strong the sense of a pattern.
Progressive discipline is the cheapest dispute-avoidance tool an employer has: most warnings work, the conduct stops, and nobody ever sees the CCMA. But it only works as a system — dates tracked, expiries known, escalation earned. A drawer full of undated, expired, unrelated warnings is not a system. It is the case the employee's representative builds against you.
CasePilot tracks every warning with its type, offence, and expiry date calculated automatically — verbal, written, and final — and reminds you by email and SMS at 30, 7, and 1 days before a warning lapses, so escalation decisions are made on live paper, not stale memory.
