Performance
Employee Warning Letter Email Template
Issue a formal written warning for policy violations or performance issues with required corrective actions.
When to use this template
An employee has violated company policy or exhibited unacceptable behavior, and you need to issue a formal written warning that documents the incident and required corrective actions.
Example subject line
Formal Written Warning — Attendance Policy Violation, Immediate Corrective Action Required
Tips for writing this email
- Describe the specific incident or behavior with dates, times, and factual details — for example, "On March 12, you were absent without notification for the third time this quarter."
- Reference the exact company policy, handbook section, or code of conduct that was violated so the employee understands the standard.
- State the required corrective action and the timeline for compliance, along with the consequences of continued violations.
- Include a signature line for both the manager and the employee to acknowledge receipt — this creates a documented record in the employee's personnel file.
What to avoid
- Do not issue a written warning based on hearsay or unverified complaints — investigate the facts before documenting.
- Avoid using emotional, subjective, or inflammatory language — the warning should read as a factual HR document, not a personal reprimand.
- Do not skip the opportunity to restate expectations and offer support — a warning should correct behavior, not just punish it.
- Avoid inconsistent enforcement — issuing warnings to some employees but not others for the same behavior exposes the company to discrimination claims.

Generate This EmailFrequently Asked Questions
When should a written warning be issued?
After verbal feedback and informal conversations have failed to correct the behavior. A written warning should never be the first time an employee hears about a performance or conduct issue.
What must a formal warning letter include?
The specific incident with dates and facts, the company policy or rule that was violated, the required corrective action, a timeline for compliance, the consequences of continued violations, and a signature line for acknowledgment.
Can an employee refuse to sign a written warning?
Yes. If an employee refuses to sign, note their refusal on the document, have a witness present, and file it in their personnel record. The refusal to sign does not invalidate the warning.
