6 free letter of concern examples for small business, covering performance, attendance, conduct, and confirming a conversation, each written as an informal step before any warning. Download all as DOCX files in one download.

The first time I had to raise a real problem with someone on my own team, I did the thing most founders do. I said something in passing, we both nodded, and I told myself it was handled. Three months later the same issue came back, and neither of us remembered the conversation the same way. That gap is what a letter of concern closes.

A letter of concern sits in the space between a quiet word and a formal warning. It is written, it is dated, and it is specific, but it is not discipline and it says so on its face. For a small business that is often the exact tool you need: enough weight that the message lands, not so much that a first mistake turns into a file entry the person carries for a year.

Below are six letter of concern examples covering the situations that actually come up: general, performance, attendance, conduct, a summary letter after a verbal conversation, and a short plain version for a small team. Each is free, fill in the blanks, and written to stay clearly on the informal side of the line.

TL;DR
A letter of concern is an informal, non-disciplinary letter that raises a problem in writing before any warning. It states dated facts, the expectation, the support on offer, and a check-in date, and carries no termination language.

What a Letter of Concern Is

A letter of concern is a short written note from a manager or owner that raises a performance, attendance, or conduct issue before any formal discipline starts. It records what was observed, the expectation going forward, and a date to check in, and it states plainly that it is not a warning.

You will see the same document called a counseling letter, a counseling memo, or a letter of caution. The names differ by industry; the function does not. Stanford's staff policy draws the line most clearly, splitting corrective action into informal non-disciplinary corrective action, such as verbal and written coaching, and formal disciplinary corrective action, such as written warnings that go in the personnel file. A letter of concern sits squarely in the first category.

That placement is the whole design. Because the letter carries no consequence, you can send it early, while the problem is one month old rather than one year old. Most concerns raised at that stage never need a second document, which is the outcome you actually want.

Letter of Concern vs Written Warning

A letter of concern is informal and carries no consequence; a written warning is a formal disciplinary step that goes in the personnel file and states what happens if the issue continues. Choosing between them comes down to how serious the issue is and whether you have raised it before.

Letter of concernWritten warningImprovement plan
StatusInformal, not disciplineFormal disciplinary stepFormal, structured program
Typical triggerA first, minor, correctable issueA repeat issue, or a serious oneSustained performance below standard
Consequence languageNoneFurther discipline up to terminationTermination if targets are missed
Usual filingManager or supervisor filePersonnel filePersonnel file
LengthOne pageOne to two pagesMulti-week plan with milestones
What closes itA check-in with the issue resolvedA review date with the issue resolvedMeeting the plan targets in full

The practical rule I use: if I would be uncomfortable saying out loud that the person's job is at risk, the document should not imply it. A letter of concern that borrows warning language is the worst of both, because it frightens the employee without giving you the record a real warning creates.

Escalation runs in one direction. If the concern repeats past the check-in date, the next step is a first written warning, then whatever your progressive discipline policy defines.

For sustained performance problems rather than a single lapse, a performance improvement plan is usually the better next document. The letter of concern still helps in that case, because it shows the standard was raised and explained before the formal plan started.

What to Include, and What to Leave Out

A complete letter of concern answers four things: what this document is, what happened, what you need instead, and when you will look at it again. What you leave out matters just as much, because one borrowed sentence from a warning template changes the character of the whole letter.

Include: the frame
Who it is from, to, and the date
A sentence saying this is not discipline
Why you are raising it now
Include: the substance
Dated, observable facts
The standard and where it is written
The effect on the team or customers
Include: the path forward
Support you are actually offering
A named check-in date
Room for the employee to respond
Leave out
Termination or final-warning language
A warning-level checkbox
Anything you have not verified yourself

The support line is the part most templates skip and the part employees notice first. Asking what is going on, and offering something concrete, is what separates a letter that fixes a problem from one that just records it.

Which Letter of Concern Should You Use?

Pick by the situation, not by severity, since every version here is informal by design. One is all-purpose, three are organized by issue type, one confirms a conversation you already had, and one is a stripped-down version for a small team that does not want a formal document.

General Letter of Concern
All purpose
The default version: the observation, the expectation, the support on offer, and a check-in date, with a plain line saying this is not a disciplinary action. Use it when no issue-specific version fits.
Performance
Quality, output, deadlines
For work that is slipping: dated examples, the countable standard for the role, the support you are offering, and a named next step if the standard is not met by the check-in.
Attendance and Lateness
Early pattern, not yet a warning
For a small attendance pattern: each occurrence with scheduled and actual times, the call-out procedure, and a stop-and-check reminder about protected leave before you send it.
Conduct and Professionalism
How something landed
For behavior that affected the people around it: what was said or done, who it affected, and the standard going forward, with a note on when the situation is too serious for this letter.
After a Verbal Conversation
Confirming what was said
The summary letter you send after a talk: the concern, what each side agreed to, the check-in date, and an invitation to correct the record if the employee remembers it differently.
Short Small Business Version
Plain and brief
A few lines on company letterhead: the concern, what you saw, what you need instead, what you can offer, and a date to talk again. For a small team that does not want a formal document.
Match the Letter to the Situation
Work that is slipping: Performance. A small pattern of lateness or absence: Attendance, and check your attendance policy first. Behavior that affected other people: Conduct. A talk you already had and want on paper: After a Verbal Conversation. Nothing fits, or you want one standard form: General. A small team where a formal letter would feel strange: Short Small Business Version.

Letter of Concern Examples, Line by Line

The difference between a letter that works and one that backfires is almost always a single sentence: whether you described behavior or described the person. Here are the lines that do the real work, in the weak version most letters use and the version worth sending.

What you are trying to sayThe version that failsThe version worth sending
Framing the letterThis is a formal notice regarding your conduct.I am raising a concern in writing. This is not a warning and not a disciplinary action.
The performance issueYour work has not been up to standard lately.The March 4, March 11, and March 18 reports each came in a day after the deadline and needed corrections.
The attendance issueYou have been late a lot.You were scheduled at 8:00 and arrived at 8:40, 8:25, and 9:05 on the 6th, 9th, and 14th.
The conduct issueYou have a bad attitude with the team.In the Tuesday staff meeting you interrupted two colleagues and raised your voice when given feedback.
The expectationPlease do better going forward.Reports are due by 5:00 on the Friday of each week, complete and proofread, starting this week.
The supportLet me know if you need anything.I can move the deadline to Monday, or pair you with Dana for the first two, whichever helps more.
The closeFailure to improve may result in termination.Let us review this together on April 8 and confirm the concern is resolved.

Every improved line has the same two properties: it is checkable, and it is about work rather than character. A person can change what they do on a Tuesday; nobody can act on the word attitude.

One more habit worth copying. Read the letter back and delete anything you did not see yourself. Secondhand reports belong in a conversation where you can ask questions, not in a document with your signature at the bottom.

Does It Go in the Personnel File?

Usually not, and that is a deliberate choice rather than an oversight. Because a letter of concern is informal, most employers keep it in a manager or supervisor file and reserve the personnel file for formal warnings, so the difference between the two stages stays real.

Federal agency practice draws the same line. Under USDA's human resources desk guide, informal cautionary and warning letters are not maintained in an employee's Official Personnel Folder but are kept in a supervisor's file, while a letter of reprimand, described there as the minimum official disciplinary action, is filed in the Official Personnel Folder for up to two years. Small employers can borrow that structure without borrowing the bureaucracy.

Decide where it lives before you send it
A letter of concern is informal, so where you file it is a choice rather than a rule, and the choice has consequences. Federal practice draws the line clearly: informal cautionary and counseling letters stay in the supervisor’s own file, while a formal reprimand goes into the official personnel record. Copy that logic. Keep the letter of concern in a manager file or a dated notes folder, and reserve the personnel file for formal warnings. Whatever you decide, do it the same way for everyone, because a letter kept on one person and shredded for another is exactly the inconsistency that gets picked apart later. Write your choice into your handbook so no manager has to guess. This is general information, not legal advice.
It still counts as evidence, so write it that way
Informal does not mean invisible. If a termination is ever challenged, the letter of concern is likely to surface, and it will be read closely. That cuts both ways. A dated, factual letter that shows you raised the issue early, offered help, and set a check-in is good evidence of a fair process. A letter full of adjectives, guesses about motive, or complaints you never verified is the opposite. Write every letter of concern as if a stranger will read it in two years with no context, because that is the realistic case. Keep it to what you saw, when you saw it, and what you asked for. This is general information, not legal advice.
Check the timing before you send
Pause if the concern lands right after the employee did something protected: filed a complaint, reported harassment, asked about pay, requested an accommodation, or took leave. The letter may be entirely fair and still look like payback because of when it arrived. That is the whole shape of a retaliation claim. If the timing is awkward, it does not mean you cannot raise the concern; it means you should be able to show the concern predates the protected activity, that you have the dated notes to prove it, and that you would treat anyone else the same way. When the situation is close to the line, get advice before you send. This is general information, not legal advice.
Set an end date and honor it
A letter of concern should close. Decide up front how long it stays relevant, for example six months from the check-in date, and say so in your handbook. If the issue resolves and does not come back, stop referencing the letter. Keeping an old concern alive indefinitely turns an informal, corrective step into a permanent mark, which is unfair to the employee and undermines the reason the letter worked in the first place. It also weakens you later: a manager who cites a two-year-old concern letter as grounds for a warning looks like someone building a case rather than managing a problem. Close it, note that it closed, and move on. This is general information, not legal advice.
Check the Timing, and Check for Protected Leave
Two things to verify before a letter of concern goes out. First, timing: the EEOC reports that retaliation is the most frequently alleged basis of discrimination in the federal sector, and a concern raised days after someone filed a complaint or requested an accommodation invites exactly that reading, however fair the concern is. Second, attendance: the Department of Labor sets FMLA coverage at private employers with 50 or more employees in 20 or more workweeks, so smaller employers are outside FMLA, but state and local sick leave laws and disability accommodation obligations can still apply. Confirm before you write a date into an attendance letter. This is general information, not legal advice.

Filing consistently is half the job. Keeping informal and formal records in separate, findable places is a small piece of organized employee files, and it is what makes the informal step defensible.

Raising a Concern Without an HR Department

Most guidance on this assumes an HR team sitting between the manager and the employee. On a small team there is no buffer: the person you are writing about is the person you eat lunch with. That changes the calculation, and it is why the informal letter is often the right first move.

You do not want to blow up a good working relationship over one bad month
This is the reason the letter of concern exists, and it is the reason most small business owners reach for one. On a small team you sit next to the person you are writing about. A formal warning changes the temperature of that room, sometimes permanently, and for a first slip it is often out of proportion to the problem. A letter of concern gives you a middle option: it is on paper, it is dated, it is specific, and it says in plain words that it is not discipline. You get the clarity of writing without the escalation of a warning, and the employee gets an honest signal while there is still time to act on it.
The concern you raised out loud somehow never happened
Every owner has had this conversation twice. You raised something in a hallway, the employee nodded, and three months later neither of you remembers it the same way. Writing it down solves that, and it solves it without a formal file entry. The after-a-conversation template exists exactly for this: it summarizes what was said, names what each side agreed to, sets the date you will check in, and invites the employee to correct anything you got wrong. That last part matters more than it looks. An employee who can put their version in writing is far less likely to argue later that the concern was never raised at all.
You raise the concern, then nobody follows up and it repeats
A letter of concern without a check-in is a complaint, not a process. The check-in date is the working part of the document, and it is the part that gets forgotten first when the owner is also doing sales, scheduling, and payroll. FirstHR fits this people side: capture the employee’s acknowledgment with e-signature so there is a timestamped record the letter was received, keep it in document management and on the employee profile so it is findable, and run the check-in as a tracked task so the date does not slip. To be clear about scope, FirstHR is an onboarding and HR platform, not a law firm, and it does not run payroll or administer benefits, so pair it with those and consult counsel for legal questions. The templates below work on their own; FirstHR is how the follow-up actually happens.

The pattern that works for a team without a dedicated HR department is to make the informal step routine rather than dramatic. Write the expectation into your employee handbook, use the same template every time, and let the letter of concern be a normal part of managing rather than a signal that something has gone badly wrong.

Doing it early also pays for itself. Replacing someone carries a real cost of turnover, and a concern raised in month two is far more likely to be fixable than the same concern raised in month ten. Applicant tracking is coming soon to FirstHR, so for now the cheapest hiring decision available is usually keeping the person you already trained.

Deliver, Acknowledge, File, Follow Up

A letter of concern only works if it is delivered in person, acknowledged, filed where you can find it, and followed up on the date you named. The document is the easy part; the check-in is what makes it worth writing.

Write it the same day
Fill in the matching template while the dates and details are fresh, and keep it to what you actually observed rather than what you were told.
Deliver it in person, then in writing
Hand it over in a short conversation and capture acknowledgment. E-signature gives you a timestamped record that the letter was received and discussed.
File it where informal notes live
Store it in document management and on the employee profile, kept separate from formal warnings so the distinction between the two stays real.
Run the check-in as a task
Track the check-in date so it happens. That meeting either closes the concern or moves it to a formal step, which is the whole point of writing it.

The templates above work on their own. To handle the delivery and follow-up without paper, FirstHR captures acknowledgment with e-signature, keeps the letter in document management and on the employee profile, and runs the check-in date as a tracked task so it does not quietly pass. FirstHR is an onboarding and HR platform, not a law firm, and it does not run payroll or administer benefits, so pair it with those and consult counsel for legal questions.

Most concerns are cheaper to prevent than to write up. Clear expectations set during onboarding, a written 30-60-90 day plan, and an early check-in remove the ambiguity that produces half these letters. Applicant tracking is coming soon to FirstHR, so the employee record currently starts on day one rather than at the offer, which makes that first onboarding week the place to set the standards you would otherwise be writing letters about.

The same is true one step earlier. A role scoped before you interview, with the standard written into the job description rather than assumed, produces far fewer surprises in month three. Applicant tracking is coming soon to FirstHR.

Key Takeaways
A letter of concern raises an issue in writing before any discipline, and it should say on its face that it is not a warning.
Include dated facts, the expectation and its source, real support, a check-in date, and room for the employee to respond.
Leave out termination language and warning levels; one borrowed sentence turns an informal letter into a formal one.
Describe behavior, not character: three dated missed deadlines beat the words poor performance every time.
Keep it in a manager file rather than the personnel file, apply that rule to everyone, and set an end date after which a closed concern is not cited.
Pause on timing if the concern follows protected activity, and confirm leave rights before writing dates into an attendance letter.

Frequently Asked Questions

What is a letter of concern to an employee?

A letter of concern is a short, informal letter a manager or owner sends to raise a performance, attendance, or conduct issue in writing before any formal discipline begins. It names what was observed and when, states the expectation going forward, offers whatever support is realistic, and sets a date to check in. It is also called a counseling letter, a counseling memo, or a letter of caution. The defining feature is what it is not: it is not a warning, it carries no termination language, and it does not start a disciplinary record. Employers use it because a written record is more reliable than a hallway conversation, while a formal warning would be out of proportion to a first, correctable problem. Written well, it usually ends the issue without anything further.

Is a letter of concern a disciplinary action?

No. A letter of concern is a non-disciplinary step, and the letter itself should say so in plain words. It documents that a concern was raised and discussed; it does not impose a consequence, does not put the job at risk, and does not commit you to any next step. The distinction is standard in mature HR policy. Stanford’s staff policy splits corrective action into informal non-disciplinary action, such as verbal and written coaching, and formal disciplinary action, such as written warnings that go into the personnel file. Federal practice makes the same split between informal counseling letters and an official reprimand. Keep that line visible in your own documents: if a letter threatens termination or names a warning level, it has stopped being a letter of concern and has become a warning.

What is the difference between a letter of concern and a written warning?

The difference is status, tone, and consequence. A letter of concern is informal, corrective, and usually kept in a manager file; a written warning is a formal disciplinary step that goes into the personnel file and forms part of a progressive discipline record. A letter of concern describes the issue and asks for a change by a check-in date. A written warning does that too, but adds a warning level, states that further problems may lead to further discipline up to and including termination, and expects a signature on a formal document. Use the letter of concern for a first, minor, correctable issue where a warning would feel like an overreaction. Move to a written warning when the concern repeats, when the issue is serious on its own, or when the check-in date passes with nothing changed.

How do you write a letter of concern?

Write it in five parts and keep it to one page. First, say what the letter is and what it is not, so the employee is not reading a warning by mistake. Second, describe what you observed as dated, checkable facts rather than as a judgment about the person: three specific missed deadlines with dates beats the phrase poor performance. Third, state the expectation and where it comes from, whether that is the handbook, the job description, or a standard you set together. Fourth, offer real support and ask what is going on, because a concern raised without a question is a complaint. Fifth, set a check-in date and leave space for the employee to respond in writing. Then deliver it in person rather than by email alone, and file it consistently.

Does a letter of concern go in the employee’s personnel file?

That is your choice, and the more common practice is to keep it out. Because the letter is informal, many employers store it in a manager or supervisor file rather than the official personnel record, reserving that record for formal warnings. Federal agency guidance follows the same pattern: informal cautionary and counseling letters stay in a supervisor’s file, while a letter of reprimand is filed in the Official Personnel Folder for a set period. Whichever approach you take, apply it identically to every employee and write the rule into your handbook. Also treat the letter as discoverable regardless of where it sits: if a decision is ever challenged, an informal letter can still be read, so it should be factual and dated either way. Set an end date after which a closed concern is no longer cited.

Does an employee have to sign a letter of concern?

No, and a refusal changes nothing about the letter. A signature on a letter of concern confirms receipt and discussion, not agreement, and the acknowledgment line should say exactly that. Because the letter is informal, some employers skip the signature entirely and simply note the date it was delivered and discussed. If you do ask for a signature and the employee declines, write on the letter that it was reviewed with the employee who chose not to sign, add the date, and keep your copy. Leaving a space for the employee’s own written response is worth doing regardless. It gives you their version while the facts are fresh, it often surfaces a cause you did not know about, and it demonstrates that the process gave the employee a real chance to be heard.

Can a letter of concern lead to termination?

Not by itself, but it can be the first document in a chain that ends there. The letter imposes no consequence and does not put employment at risk on its own. What it does is establish, with a date, that the issue was raised and that the employee was given a chance to fix it. If the problem continues past the check-in, the usual next step is a formal written warning, then whatever your progressive discipline process defines, with termination as a last resort. That earlier letter then becomes useful context showing the process was fair rather than sudden. This is also why the letter should never carry termination language: borrowing warning wording for an informal letter removes the correction window and makes the document harder to explain later.

When should you skip the letter of concern and go straight to a warning?

Skip it when the conduct is serious, when it repeats, or when your own handbook requires a formal step. A letter of concern is the right tool for a first, minor, correctable issue. It is the wrong tool for harassment, threats, violence, theft, safety violations, or anything involving discrimination, all of which call for an investigation and a formal process rather than an informal note. Skip it as well when you have already raised the same issue informally and nothing changed, because a second informal letter signals that the deadline was never real. And check your handbook first: if your written policy defines a specific sequence for a given category of issue, follow that sequence, since your own stated policy can create expectations you then need to honor.
