This document creates clear, fair documentation while opening an honest path for improvement.

Too many leaders rush this step, skip critical details, or write letters that demoralise instead of support. In this guide, you will learn when to use this letter, see real usable examples for every common situation, and get answers to the questions every manager asks.

Why This Letter Matters More Than You Think

A Sample Letter of Concern for Poor Performance is not a punishment. It is a formal, neutral record that protects both your employee and your organisation. It eliminates he-said-she-said disagreements and sets clear shared expectations.

This letter is the first critical step in fair performance management, not the final warning. Before you draft one, you should always confirm you have:

• Already had at least one verbal conversation about the performance gap
• Documented specific examples of missed standards
• Shared clear measurable targets previously with the employee

Different scenarios require different tone and details. Use this quick reference to match your letter approach:

Sample Letter of Concern for Poor Performance: Missed Deadlines

Subject: Performance Concern: Project Deadline Deliverables

Hi Alex,

This letter formalises our conversation yesterday regarding missed project deadlines over the last 6 weeks. On three separate occasions, assigned deliverables were submitted 2-4 business days late without advance notice.

I understand workload shifts happen. Moving forward, we have agreed you will flag potential delays at least 48 hours in advance, and we will check in briefly every Wednesday afternoon. We will review progress again in 30 days.

Please reach out anytime you need support. I want you to succeed here.

Regards,
Maria Carter
Team Lead

Sample Letter of Concern for Poor Performance: Work Quality Errors

Subject: Concern: Recent Work Quality Standards

Hi Jamie,

This letter follows our meeting today about recurring errors in client report submissions. Over the last month, 4 out of 6 reports you submitted required major corrections before we could send them to clients.

We have agreed you will use the new checklist for all reports, and Sam will do a 10 minute review of your first three submissions next week. You can also book extra training on the reporting tool this week if that would help.

Let me know what additional support you need.

Thank you,
David Reed
Department Manager

Sample Letter of Concern for Poor Performance: Attendance & Punctuality

Subject: Formal Concern: Attendance and Arrival Times

Hi Riley,

This letter documents our discussion about your recent attendance. Over the last 8 weeks you have arrived late 7 times and called out sick on 4 unplanned occasions with less than one hour notice.

This pattern makes it very hard for the rest of the team to plan their daily work. We have agreed on a modified arrival window for the next month, and you will text me by 7:30am if you cannot make it in that day.

We can adjust this plan as things improve. Please talk to me if something outside work is affecting you.

Best,
Lori Chen
Supervisor

Sample Letter of Concern for Poor Performance: Team Collaboration Issues

Subject: Performance Concern: Team Collaboration

Hi Jordan,

This letter formalises our conversation about team working practices. Multiple team members have shared that you do not reply to messages, skip scheduled check ins, and do not share updates on your work progress.

Good teamwork relies on open communication. For the next 30 days you will update the team slack channel each afternoon with your daily progress, and attend all scheduled team meetings.

I am happy to work through any frustrations you have about team processes.

Regards,
Ben Morales
Project Manager

Sample Letter of Concern for Poor Performance: Client Feedback Concerns

Subject: Concern Regarding Recent Client Interactions

Hi Taylor,

This letter follows our meeting today about feedback we have received from two separate clients. Both clients noted that calls were not returned, questions went unanswered, and they did not feel supported.

Client trust is the foundation of our work. We will be shadowing 3 of your client calls this week, and you will send a follow up summary after every client conversation.

I know you can do great work with clients. Let's get you back on track.

Thank you,
Sarah Holt
Account Director

Sample Letter of Concern for Poor Performance: First Formal Warning Stage

Subject: First Formal Performance Concern Letter

Hi Cameron,

This is the first formal written letter of concern regarding your job performance. We have had two verbal conversations in the last two months about performance standards, and no sustained improvement has occurred.

Attached is a 30 day performance improvement plan with clear measurable targets. If these targets are not met, further disciplinary action will be taken including possible termination.

You may bring a support person to all follow up meetings about this plan.

Regards,
Human Resources Department

Sample Letter of Concern for Poor Performance: Remote Worker Productivity

Subject: Performance Concern: Remote Work Output

Hi Morgan,

This letter formalises our conversation about remote work productivity. Over the last month we have seen a 40% drop in completed tasks, and you have been unresponsive during scheduled work hours on 5 occasions.

We have agreed to set daily check ins at 9am for the next four weeks, and you will share an end of day task summary each working day. We can also adjust your workload if that will help.

Please let me know what barriers you are facing working from home.

Best,
Kelly Grant
Remote Team Lead

Frequently Asked Questions about Sample Letter of Concern for Poor Performance

When should I send a letter of concern for poor performance?

Send this letter after you have had a verbal conversation about the issue and seen no improvement. This should always be the first formal written step, not an unexpected first communication.

Do I need to give the employee a copy of this letter?

Yes, always provide a physical or digital copy directly to the employee. You should also keep a signed copy in their official personnel file for future reference.

Should a letter of concern go in the employee file?

Yes. This is official workplace documentation that belongs in the employee's personnel file. Most companies remove these records after 12 months if performance improves consistently.

How long after a conversation should I send the letter?

Send the letter within 24 hours of your verbal discussion. This ensures all details are fresh and the employee does not feel blindsided by delayed formal communication.

Can an employee refuse to sign the letter?

Yes, an employee can refuse to sign. Simply note on the document that the employee received the letter but declined to sign, and add the date. This still counts as valid documentation.

What tone should I use in this letter?

Use neutral, factual and supportive tone. Avoid emotional language, stick only to verifiable facts, and always include clear next steps for improvement.

Is a letter of concern the same as a written warning?

No, a letter of concern is an early formal notification. A written warning comes later if performance does not improve, and carries formal disciplinary consequences.

What should I never include in this letter?

Never include opinion, personal criticism, or references to other unrelated employee issues. Never use this letter to punish, only to clarify expectations and offer support.

How long does a performance concern stay on record?

Most companies keep performance concern letters on file for 6 to 12 months. If the employee meets and maintains expected standards during this time, you can remove the letter.

A well written Sample Letter of Concern for Poor Performance turns an awkward workplace conversation into an opportunity for growth. It removes ambiguity, treats employees fairly, and protects everyone involved when done correctly. Always remember this document exists to help people improve, not just document problems.

Before you send any letter, take one extra minute to read it through from the employee's perspective. Adapt the templates above to match your situation, and always leave the door open for honest follow up conversation. You will build stronger teams and avoid unnecessary conflict when you approach this process with respect.
