How to write an employee warning letter fairly

An employee warning letter is a short, factual document that tells a person what went wrong, what the standard is, what must change and by when, and what the next step is. Written well, it is fair to the employee and protects the business. Written in anger or from a rushed template, it causes disputes. This guide shows how to write one, in order.

Use the employee warning letter template for the layout.

Before you write anything

A letter should never be the first time the person hears about a problem. First:

1. Talk to them. Describe the issue, ask for their side and listen. There may be a reason you do not know.
2. Check the facts. Dates, examples, numbers, witnesses. If you cannot show it, do not write it.
3. Check the rules. The contract, the staff handbook and local law set the steps.
4. Compare cases. Treat like cases alike. A different outcome for the same issue needs a reason.
5. Think about support. Training, tools, workload or health may be part of the problem. See our guide on how to handle a performance problem fairly.

What the letter should contain

1. Names and date. Employee, writer, date, and a line saying whether this is a first, second or final written warning.
2. The issue, in facts. "On 3, 7 and 12 March you arrived more than 30 minutes late without notice" not "you have an attitude problem".
3. The standard. The rule or expectation, with where it is written.
4. Earlier conversations. The dates of any talks or earlier warnings.
5. What must change. Specific, measurable and realistic: "arrive by 9:00 or tell your manager before 8:30."
6. Support offered. What you will do to help.
7. A review date. When you will check progress.
8. The consequence. What may follow if it does not improve, stated plainly and not as a threat.
9. Their right to respond. A meeting, a written reply, and a right to be accompanied where the rules provide it.
10. How long it stays on file. Many policies set a period, such as six or twelve months.

Wording that works

• Use short sentences and plain words.
• Describe behaviour, not character.
• Stay calm. No sarcasm, capital letters or exclamation marks.
• Do not mention other staff by name.
• Keep to one issue per letter where you can.

Weak: "You are lazy and your work is always late."

Better: "The three reports due on 5, 12 and 19 March were delivered on 8, 17 and 25 March. The standard is delivery by the due date. Please deliver the April report by 5 April. If you think a deadline is not realistic, tell me at least two days before."

The meeting

Deliver the warning face to face, or by video if you must. Allow time, read the key points, let the person respond and write down what they say. Give them the letter in the meeting, ask for a signature to confirm receipt (not agreement) and keep a copy.

After the letter

• Keep your promises. If you offered training, give it.
• Check in at the review date and record the result.
• Recognise improvement. Tell the person when the problem is solved and the warning is closed.
• Store it safely. Warnings are personal data. Keep them in the personnel file with limited access and delete them when your policy says so.
• Next step. If nothing improves, the next step may be a final warning or a meeting about ending employment. Use the termination letter only after you checked the process.

Common mistakes

• Skipping the conversation and going straight to the letter.
• Mixing several unrelated problems in one letter.
• Vague wording like "improve your attitude".
• Setting a standard that nobody else is held to.
• Writing in anger and sending the same day.
• Putting it in an email chain copied to others.

For regular, calmer feedback that prevents warnings, see feedback and surveys and keep a routine of one to ones, as in run one to ones that people value.

First, second and final warnings

Many policies use stages. A rough pattern, which you should adapt to your country and contract, is:

Some conduct, such as theft or violence, can be treated as serious from the start. Even then, investigate and hear the person's side before you decide anything.

Performance or conduct

The two need different handling. A performance problem means the person cannot or does not reach the standard of the work: quality, speed, results. Support matters more here: training, clear targets, time. A conduct problem is about behaviour: lateness, rudeness, breaking rules. Here the rule and the facts matter most. The letter looks similar, but the plan differs. For performance, set a plan with checkpoints. For conduct, state what must stop.

Special cases to handle carefully

• Illness or disability. A problem may be linked to health. Ask what support is needed and get advice before you warn.
• Pregnancy, parental leave or protected reasons. Treating someone badly for these reasons is unlawful in many countries.
• Complaints and whistleblowing. Never warn someone because they raised a concern.
• Cultural and language differences. Check the person understood the rule and the letter. Offer to explain it, or provide a translation.
• Small teams. When everyone knows everyone, privacy is harder. Keep the discussion private and do not talk about it with others.

A sample paragraph set

Issue: "On 3, 7 and 12 March you arrived more than 30 minutes after your 9:00 start without telling me beforehand. Our attendance policy, section 4, requires notice before the start if you will be late."

What must change: "From today, please arrive by 9:00, or message me before 8:30 if you cannot. I will check attendance each week for the next two months."

Support: "If something is making it hard to arrive on time, please tell me, and we can look at options such as a changed start time."

Consequence: "If attendance does not improve, we may need to take further steps under the disciplinary policy, which could include a final written warning."

Response: "You are welcome to reply in writing or ask for a meeting within seven days."

Adapt these to your facts, and have someone else read the letter for tone before you send it.

The short version

Talk first, check the facts and rules, then write a short letter with facts, the standard, what must change and by when, the support you offer, a review date and the consequence. Deliver it in a meeting, keep it private, and follow up. When in doubt, ask an adviser.
