Managing and dealing with employee performance or behavioural issues is a critical aspect of the overall HR function in any organisation. It’s a concern no manager or business owner can take lightly. Though uncomfortable and complex, when handled properly, giving a written warning can be a constructive and positive step forward.
Why Written Warnings Matter in HR Management
Employers need to issue warnings when ongoing issues with performance, behaviour, or policy breaches haven’t improved despite informal communication or feedback.
Warnings serve as formal tools in human resource management to correct issues while promoting fairness, accountability, and clear communication. They help reinforce expected standards and protect the integrity of workplace culture.
When timely and constructive, written warnings support positive organisational behaviour by encouraging improvement rather than punishment. As part of a structured disciplinary process, they contribute to a healthy work environment and demonstrate that your organisation values professionalism, transparency, and employee well-being.

When Should You Issue a Written Warning?
A written warning is a formal notice issued to an employee when ongoing issues related to performance, behaviour, or policy violations haven’t improved despite prior feedback or informal discussions.
It’s not about punishment—it’s about promoting accountability, clarifying expectations, and encouraging improvement. Think of it as a documented signal that a line has been crossed, and action is needed.
Common scenarios include:
- Repeated lateness
- Ongoing underperformance
- Breach of company policies (not serious enough for dismissal)
A written warning should only be issued after a fair and transparent disciplinary process. This ensures your actions are legally compliant and ethically sound.

Step-by-Step: How to Give a Written Warning
Step 1: Follow a Fair Disciplinary Process (ACAS Guidelines)
Before proceeding, you must follow a fair disciplinary procedure in line with the ACAS Code of Practice.
Skipping these steps could expose your business to legal risks—even if the behaviour in question seems obviously unacceptable.
A fair process includes:
- Gathering facts and evidence
- Reviewing relevant documents
- Speaking with witnesses or involved parties
- Assessing whether formal disciplinary action is warranted

Step 2: Notify the Employee in Writing and Schedule a Hearing
Once you’ve decided to proceed, notify the employee in writing about the issue. This should:
- Clearly outline the concerns
- Provide evidence
- Invite the employee to a disciplinary hearing
Ensure the employee has adequate time to prepare and inform them of their right to be accompanied by a colleague or union representative.
Step 3: Conduct the Disciplinary Hearing Fairly
The hearing gives the employee a chance to explain their side.
They may provide mitigating circumstances or agree to improve. Either way, keep an open mind and carefully review all evidence before deciding next steps.
Step 4: How to Draft an Effective Written Warning Letter
If you conclude that a written warning is appropriate, the letter should:
- Describe the issue clearly
- Summarise previous discussions or support provided
- Specify the improvements expected and deadlines
- Detail the support the company will provide
- Outline potential consequences for not improving
- Explain the right to appeal and how to initiate it

Step 5: Deliver the Warning and Communicate Expectations
Deliver the warning promptly—in person or via email with receipt confirmation.
Allow the employee to ask questions and ensure they fully understand what’s expected of them. Your tone should be professional, clear, and focused on growth—not punishment.
What to Do After Issuing a Written Warning
Issuing the warning is only the first step. Afterward, it’s essential to support the employee’s improvement and track their progress.
- Set Clear Expectations: Reiterate what needs to change, by when, and what support will be provided.
- Offer Support: Provide necessary tools or training to help the employee succeed.
- Monitor Progress: Schedule regular check-ins and document improvements or ongoing concerns.
- Acknowledge Effort: If the employee shows progress, recognise it. Positive feedback can reinforce the desired behaviour.
- Escalate if Needed: If there’s no improvement, follow your disciplinary procedure—this may include a final warning or further action.

How Long Does a Written Warning Stay on Record?
Typically, a written warning remains active for 6 to 12 months, depending on your internal policy.
If no further issues occur during this period, the warning is usually considered “spent”—though retained for internal reference.
Stay Compliant: Legal Frameworks to Follow
Make sure you’re legally protected by following the UK’s employment legislation, including:
- Employment Rights Act 1996
- ACAS Code of Practice
- Equality Act 2010
Inconsistencies or poor process execution could result in formal grievances or tribunal claims.
🛡️ Avoid legal risks—Clear Path Solutions can review your existing disciplinary policies to ensure full compliance.
Final Thoughts: A Written Warning as a Path to Improvement
Issuing a written warning doesn’t have to be negative. When delivered fairly and constructively, it can prompt reflection, encourage growth, and lead to long-term improvement.
Approach it as an opportunity to open dialogue and support professional development—not just a disciplinary action.
