An Employee Warning Letter is a formal document issued by an employer to an employee in response to misconduct, poor performance, or policy violations. Its purpose is to clearly communicate the nature of the issue, set out expectations for improvement, and warn of potential consequences if the issue continues.

A written warning forms part of a fair and structured disciplinary process, helping employers manage workplace standards while giving the employee a fair opportunity to improve.

When should you issue a warning letter?

Before issuing a formal warning, employers are expected to follow a fair process, including meeting with the employee, allowing them to respond to concerns, and considering any mitigating circumstances.

A Warning Letter is then typically issued after informal discussions or verbal warnings have failed to resolve an issue. You may issue a warning letter in response to:

• Ongoing lateness or absenteeism
• Failure to meet job performance standards
• Disrespectful or disruptive behaviour
• Insubordination or breach of company policies
• Unauthorised use of company resources

The letter should be kept in the employee’s file and may be cited in future disciplinary actions if no improvement is made.

How to structure an Employee Warning Letter

An effective warning letter should be factual, objective, and supportive. It should include:

1. The date of the meeting where the issue was discussed
2. A clear description of the problem
3. A list of improvements required
4. The duration the warning will remain active
5. Details of any support or monitoring arrangements
6. An appeal process and point of contact
