RE: Formal Written Warning

Dear Jordan Mitchell,

This letter serves as a formal written warning regarding conduct and performance that does not meet the standards expected of employees at Acme Global Inc. The purpose of this notice is to make you clearly aware of the concern and to give you a fair opportunity to correct it.

Specifically, the following issues have been observed and documented:

  • Repeated unexcused lateness and absence without prior notice.
  • Missed deadlines affecting the wider team's deliverables.
  • Failure to follow agreed procedures after previous verbal guidance.

We take these matters seriously because they affect your colleagues, our clients, and the reliability of the department as a whole. Please treat this warning as an opportunity to reset, not merely a reprimand.

We expect to see immediate and sustained improvement. Should the concerns continue, further disciplinary action, up to and including termination of employment, may follow. We remain willing to support you with any reasonable resources needed to succeed.

Please acknowledge receipt of this letter. You are welcome to schedule a meeting to discuss it.

Sincerely,

Sarah Jenkins

Employee Warning Letter: mistakes to avoid

  • "Dear Hiring Manager" beats "To Whom It May Concern", which reads as a form letter.
  • Match the tone to the reader, not to the occasion.
  • Never send an editable Word file for anything that carries weight.
  • Read it aloud once. Anything you stumble over, the reader will too.

Frequently asked questions

What is the correct format for a Employee Warning Letter?

Sender address, date, recipient address, a salutation naming a person where possible, a subject line, the body in short paragraphs, a complimentary close, and a signature block. Block format — everything left-aligned, a blank line between paragraphs — is the safe default.

Should I send it as PDF or Word?

PDF, unless the recipient asked for an editable file. It renders identically everywhere, cannot be altered by accident, and is what HR and legal teams expect to file.

How formal should the tone be?

Match the reader. Resignation, offer and legal letters stay formal and factual. Thank-you and cover letters can be warm, but never casual — no contractions in the opening line.

Is this template free to download?

Yes. Edit it, export to PDF or Word, and send it — no account, no watermark, no limit on how many you create.
