Warning Notice for Employees

    A written warning is not mainly a telling-off. It is a record, and its whole value is that it proves four things at once: that the employee was told what was wrong, told what to change, told by when, and told what happens if nothing changes. Warnings that leave any of those out tend to be worth very little later. These six free warning notice templates in Microsoft Word are laid out so that all four end up on the page.

    This page is general information, not legal advice, and disciplinary rules differ by country. The procedural detail below follows the Acas Code of Practice on Disciplinary and Grievance Procedures, which applies in Great Britain. If you are elsewhere, the documents still work but the process around them will not be the same — there is a section on at-will employment further down. Before dismissing anyone, or in any case involving health, disability, pregnancy, a protected characteristic or a whistleblowing complaint, take advice specific to your jurisdiction.

    Get the order right, then worry about the wording

    Most warning notices that fail do so because of when they were sent, not how they were written. The sequence below is the one the Acas Code sets out, and it only runs in this direction.

    1. Establish the facts first

      Find out what actually happened before you commit anything to paper. If someone has been absent without explanation, the explanation may be illness, a family emergency or a message that never arrived. A warning issued before you have asked is a warning you may have to withdraw.

    2. Invite the employee in writing

      The Code says that where there is a disciplinary case to answer, the employee should be notified in writing, with enough detail about the allegation and its possible consequences to let them prepare, normally including copies of any written evidence and witness statements, plus the time and venue of the meeting.

    3. Tell them they can be accompanied

      Workers have a statutory right to be accompanied at a disciplinary meeting that could lead to a formal warning, and at an appeal. The companion can be a fellow worker, a trade union representative or a union official. If the chosen companion cannot attend, the employer must postpone — though only to a reasonable alternative time within five working days of the date originally proposed.

    4. Hold the meeting and actually listen

      The meeting exists so the employee can respond. If what they say changes the picture, the outcome should change with it. A meeting held after the decision has been made is a formality that a tribunal can usually spot.

    5. Decide, then issue the warning in writing

      This is where the template comes in — at the end, not the beginning. Confirm the outcome in writing with the four required elements set out below.

    6. Offer an appeal

      Say in the notice that the employee may appeal, how, and by when. Appeals should be heard without unreasonable delay and, wherever possible, by a manager who was not involved in the original decision. Finding that person is easier in a large organisation than a small one; an organogram makes it obvious who is genuinely uninvolved.

    The four things a written warning must say

    Paragraph 21 of the Acas Code is unusually specific, and it is the part most warning letters get wrong. A warning should set out all four of these:

    Must state What that means in practice
    The nature of the misconduct or poor performance What happened, with dates. “Attitude problems” is not a finding. “Arrived after 09:30 on 4, 7 and 11 March without notifying your supervisor” is.
    The change or improvement required, with a timescale Both halves matter. A warning that says “improve” without saying by when cannot later be said to have been breached.
    How long the warning remains current The Code sets no fixed period, but says the employee should be told what it is. Six or twelve months are common choices. Pick one and write it down.
    The consequences of further misconduct or failure to improve Normally a final written warning, or dismissal if this is already final. It may also be another contractual penalty such as demotion or loss of seniority, where your contracts allow it.

    Two of those four are really a plan rather than a sentence. Where the problem is performance rather than conduct, the improvement and the timescale usually need their own document — a personal development plan or an improvement plan with dated review points attached to the warning does far more than a paragraph of encouragement, and it also demonstrates that you gave the person a real chance to improve.

    When a warning is the wrong document

    Written warnings deal with ordinary misconduct and underperformance. Some situations are not that, and reaching for a warning notice makes things worse rather than better.

    Gross misconduct. Violence, theft, serious dishonesty and comparable conduct are normally handled as gross misconduct, which means investigating and considering whether to suspend on full pay while you do — not issuing a warning and carrying on. Issuing a written warning for an alleged assault has two bad outcomes at once: it may be far too lenient for what happened, and it signals that the organisation treated the matter as minor, which is awkward if the same conduct recurs. The Code does allow a first offence to go straight to a final written warning where it is serious enough to have had, or be likely to have, a serious or harmful impact on the organisation — that is the route for serious-but-not-gross cases. Whether demotion or loss of seniority is available to you at all depends on what the employee’s contract says, so it is worth checking the employment agreements you issue before you threaten a penalty you cannot impose.

    Sickness absence. Absence caused by ill health is usually a capability and welfare question before it is a conduct one, and where a disability may be involved there are separate duties that a warning notice does not satisfy. Unexplained absence and sickness absence look identical until you ask, which is exactly why asking comes first.

    A grievance in disguise. If the employee’s response is that they were being bullied, overloaded or treated unfairly, you now have two processes rather than one, and pressing on with the warning alone tends to produce the complaint you were trying to avoid.

    Why this paperwork matters much more from 1 January 2027

    If you employ people in Great Britain, the value of a properly documented warning is about to increase sharply, and the change is close.

    At present an employee generally needs two years’ service to bring an ordinary unfair dismissal claim. Section 25 of the Employment Rights Act 2025 cuts that qualifying period to six months, and the Government intends it to commence on 1 January 2027. Note that figure: the original proposal was protection from day one, and it was changed to six months during the Act’s passage, so the day-one version still circulating is out of date. The transitional position is that on that date employees who already have six months’ service or more are protected straight away, and everyone else becomes protected on reaching six months.

    Two further points make the difference bigger than the headline suggests. The cap on unfair dismissal compensation is removed on the same date — it had been the lower of £123,543 or 52 weeks’ gross pay as at 6 April 2026. And the qualifying period for an employee to demand written reasons for dismissal drops from two years to six months as well, so you may be asked to justify a dismissal in writing far earlier in someone’s employment than before.

    None of this changes what a warning notice says. What it changes is how many of your employees could challenge a dismissal, and how much is at stake when they do. The practical consequence is that the first six months stop being a period where paperwork can be informal. Worth adding that protection against discrimination and against automatically unfair grounds for dismissal has never had a qualifying period and still does not — those have always applied from day one.

    There is one more reason to get the file right rather than the letter alone: a tribunal may adjust an award by up to 25% where a party has unreasonably failed to comply with any provision of the Acas Code. That cuts both ways — it can reduce an employee’s award if they ignored the Code — but for an employer it means a procedural shortcut can cost a quarter on top of a now-uncapped award.

    The Code itself is being rewritten. Acas published a substantially expanded draft replacement Code for consultation on 30 July 2026, with the consultation closing on 23 September 2026. The draft reorganises the guidance around “concerns at work”, covers a wider range of workers, and distinguishes legal requirements from recommendations and good practice. The requirements described on this page are those of the Code currently in force; check the position at the time you act.

    If you employ people in the United States

    Most US employment is at will, so there is generally no legal requirement to warn anyone before dismissing them, and no statutory three-strikes rule. That makes written warnings optional in a way they are not in Britain — and, in practice, more important rather than less.

    The reason is that although the dismissal itself may need no justification, a claim that it was discriminatory or retaliatory very much does, and a contemporaneous record of performance problems is the usual answer to it. Two cautions follow from that. First, apply your own policy consistently: if your handbook describes a progressive discipline process and you follow it for some employees but not others, the inconsistency becomes evidence about why this employee was treated differently. Second, be careful how the handbook is worded, because language promising a fixed sequence of warnings can in some circumstances be read as a commitment rather than a guideline. Those are questions for a lawyer in your state, not for a template.

    Writing the notice itself

    The templates handle the layout. What they cannot do is keep the tone usable, and tone is where warning letters are most often rewritten by somebody’s solicitor.

    Write it as though a stranger will read it, because one may — a new manager, an appeal panel, an adviser. State findings, not feelings: “did not complete the stock count on 14 April” rather than “has a poor attitude to responsibility”. Leave out anything you cannot evidence, anything about the person’s character, and any speculation about why they behaved as they did. Describe the conduct and its effect, and stop there. The same discipline that makes an internal memo hold up over time applies here, with higher stakes.

    Then make the follow-through real. A warning that sets a review date nobody diarises teaches the whole team that warnings are theatre, and it undermines the next one you issue. Put the review date and the expiry date somewhere you will actually see them, and if improvement is required against specific milestones, track them the way you would any other commitment — a short action plan with dates and owners is enough, and it gives you something concrete to review at the meeting rather than an impression.

    Questions about employee warning notices

    Is a warning notice the same as a show cause notice?

    No, although they are often conflated. A show cause notice asks the employee to explain why action should not be taken against them — it comes before any decision, and is mainly used in South Asian employment practice and in some public-sector and regulated settings. A warning notice records a decision already made after the employee has had the chance to respond. Using a warning notice to ask for an explanation, which is how these documents are often described online, gets the process the wrong way round.

    How many warnings before dismissal?

    There is no legal number. The Acas Code describes the usual pattern as a written warning, then a final written warning for a further failure within the period the first warning remains current, then dismissal — but it also allows a first offence to go straight to a final written warning where it is serious enough, and gross misconduct can justify dismissal without any prior warning. The often-quoted “three warnings” rule is custom, not law.

    How long does a written warning stay on file?

    For as long as you said it would in the notice. The Code does not fix a period; it requires that the employee be told how long the warning remains current. Six months for a first written warning and twelve for a final warning are common, but the figure is yours to set — and once it expires it should not be relied on as a live warning, even if the document stays on the personnel file.

    What if the employee refuses to sign it?

    It still stands. A signature on a warning acknowledges receipt, not agreement, and an employee is not obliged to provide one. Note on the file that the notice was issued, how and when it was given or sent, and who witnessed it. Then point them at the appeal route, which is the proper way to disagree with a warning.

    Can I issue a verbal warning instead?

    Informal conversations are often the right first step, and plenty of problems never need to go further. Just be clear with yourself about which you are doing. An informal word is not a stage in a formal process, and treating it as the first of three later — when nothing was written down and the employee did not know it counted — is where disputes start. If it matters enough to count, write it down and say that it is formal.

    Does a small business have to follow all of this?

    The Code applies regardless of size, and tribunals do consider what was reasonable for the particular employer — a business with no HR department is not expected to run a process like a large one. What is not excused by size is the basic sequence: tell the employee the allegation in writing, let them respond, let them be accompanied, decide, and allow an appeal. Those cost nothing but attention.

    Can I edit these templates?

    Yes — they are ordinary Microsoft Word files, free to download, edit and print. Do edit them: a warning notice that does not name the conduct, the required improvement, the timescale, the expiry and the appeal route is missing the parts that give it any value.
