Employee warning letter template
A formal written warning with a warning summary table and a receipt-only acknowledgment signature. Copy it, download the Word document, or send a personalized warning letter to every employee on the list at once.

An employee warning letter is a formal written record of a conduct or performance issue, what is expected going forward, and the consequences of it continuing. It is typically the first documented step in a progressive-discipline process, issued after a manager has already raised the issue verbally.
Consistent, well-documented warnings across a team or company reduce disputes and keep the process fair. Upload this letter as a Word template to MailMergic, upload a spreadsheet with the incident details for each employee, and generate one personalized, dated warning letter per row.
