A warning letter is a written notice from an employer to an employee about a documented concern, such as poor performance, repeated absence, misconduct, or a policy breach. It tells the employee what happened, what needs to change, and what may happen if the issue continues.
For Indian SMEs, the letter should be firm but fair. Keep it factual, mention dates where possible, and avoid language that sounds personal or punitive. If the matter is serious, check your company policy, employment contract, standing orders, and local labour law advice before sending the letter.
What is a warning letter?
A warning letter is an official HR record used when verbal feedback has not resolved an issue or when the issue needs written documentation. It can cover:
- poor performance or missed targets
- repeated late coming or unapproved absence
- misconduct or disrespectful behaviour at work
- breach of company policy
- failure to follow reasonable instructions
A written warning gives the employee a chance to correct the problem. It also creates a record for HR if further action is needed later.
What to include in a warning letter
A useful warning letter should answer six questions:
- Who is receiving the warning?
- What specific issue is being recorded?
- When did it happen?
- Which policy, expectation, or instruction was affected?
- What improvement is expected?
- What happens if the issue continues?
Use plain language. A manager or HR executive should be able to read the letter later and understand the facts without needing a separate explanation.

[Manager/HR name]HR tips before sending the letter
- Check that the facts are documented. Dates, attendance records, review notes, and written complaints matter.
- Keep the tone professional. Do not add anger, assumptions, or personal remarks.
- Mention the improvement expected, not just the mistake.
- Give the employee a reasonable chance to respond or clarify where your policy requires it.
- Save a signed copy or email record for the employee file.
A warning letter should make the next step clear for both sides. The employee should know what to fix, and HR should have a clean record of what was communicated.
