What a Legal Warning Letter Must Contain (South Africa)
The warning letter is the atom of progressive discipline β and the document commissioners read first and most sceptically. A warning that is vague, unsigned, or about a rule nobody knew is not a rung on the ladder; it is decoration. Here is exactly what goes into one that works.

- βSix contents: rule, facts, explanation, correction, consequence, validity period.
- βThe rule must exist and be known to the employee beforehand.
- βRefusal to sign does not void the warning β witness it and file it.
- βExpired warnings cannot support a later dismissal.
The six contents of a warning letter that survives the CCMA
Signatures, refusals and filing
The employee’s signature acknowledges receipt, not guilt β say so on the document. If they refuse to sign, note the refusal on the letter in front of a witness, hand over a copy, and file the annotated original. The warning stands either way. What does not stand is the warning that lives in nobody’s file: keep it in the employee’s record with the discipline register, because the register is what keeps your discipline consistent β and consistency is a legal requirement, not a management style.
A warning for something from months ago, produced only when the relationship sours, reads as retaliation β because it usually is. Warn close to the event, or do not warn at all.
Warning letter versus performance plan: know which one you are writing
A warning letter addresses misconduct β a rule chosen to be broken. It is the wrong tool for poor performance, which is incapacity and demands support instead: standards, training, an improvement plan, reasonable time (the crucial distinction). Employers who write ‘warnings’ for missed targets build a file that loses at the CCMA twice: wrong process, and no support evidence.
Get the ladder right and most discipline ends early β the system context is in the discipline and dismissal pillar.

Frequently asked questions
What must a written warning contain?
The specific rule breached, the facts with dates, the employee's explanation, the correction required, the consequence of repetition, and a validity period β typically six months for a written warning and twelve for a final written warning.
Is a warning valid if the employee refuses to sign?
Yes β the signature acknowledges receipt, not agreement. Note the refusal on the document in front of a witness, give the employee a copy, and file it. The warning remains valid.
How long does a written warning last?
Standard practice: six months for a written warning and twelve months for a final written warning, stated on the document itself. Expired warnings cannot support a later dismissal.
