Our First Written Warning Letter Template addresses performance issues formally, promoting improvement and setting clear expectations.

What is a First written warning letter?

A First Written Warning Letter is a formal document that is issued to an employee to address any issues or misconduct in the workplace. It is typically the first step in a progressive formal disciplinary process that aims to improve an employee's behaviour or performance.

The letter is issued after a disciplinary hearing has taken place, and typically outlines the specific concerns or issues the employer has with the employee's conduct, and sets out expectations for improvement. It may also provide details on any consequences that may result if the employee does not improve their behavior or performance, such as further disciplinary action or termination of employment.

The letter is typically kept on the employee's personnel file, and may be used as evidence in any future disciplinary proceedings. It is important for both employers and employees to take the contents of a First Written Warning Letter seriously, as it is a formal warning that there are concerns that need to be addressed.

To ensure fairness, warnings should always be issued in accordance with the Company disciplinary policy, which should follow the ACAS Code of Practice in relation to dismissal and disciplinary procedures.
