Why the wording matters more than the tone
It's tempting to think of a warning letter as just a stern version of a normal memo. In practice, it's often the document that gets pulled out later if a termination is disputed. That means precision matters more than how strict it sounds — vague accusations are harder to defend than specific, dated incidents.
What a proper warning letter includes
- The specific incident(s) — dates, what happened, and how it violates a specific policy or expectation. "Poor attitude" is not specific; "Arrived more than 30 minutes late on 5 occasions in August 2026, without prior notice" is.
- Reference to the relevant policy — the employee handbook section or company policy that applies.
- Prior discussions, if any — if this issue was raised informally before, note when and how.
- Expected corrective action — what specifically needs to change, and by when.
- Consequences of no improvement — stated plainly, without being threatening in tone.
- A record of employee acknowledgment — a signature line confirming they received it (not necessarily that they agree with it).
Keep emotion out of the language
Even when the underlying situation is frustrating, the letter itself should read as neutral and factual. Words like "constantly," "always," or "never" are rarely accurate and are easy to challenge. Stick to specific, countable incidents.
Document the pattern, not just the moment
A single warning letter referencing one isolated incident carries less weight than one that shows a documented pattern — especially if the matter is ever escalated to a labor tribunal or employment dispute. If this isn't the first conversation about the issue, say so and reference the earlier one.
