Introduction to Timelines After a Concern Letter
When an employer identifies an issue with an employee’s conduct or performance, a letter of concern is often the first formal step in addressing the matter. This document is designed to clearly outline the specific concerns, set expectations for improvement, and offer support to help the employee get back on track. Unlike disciplinary action, a letter of concern is typically informal, aiming to resolve issues early and encourage positive change without escalating to more serious procedures.
Timely communication is crucial when problems arise in the workplace. Addressing concerns promptly not only helps employees understand what’s expected of them, but also demonstrates that the employer is acting fairly and transparently. The sooner a letter of concern is sent after an issue is identified, the more effective it is likely to be in supporting improvement and maintaining trust.
Understanding the timelines involved after issuing a letter of concern is essential for both employers and employees. The improvement period provided should be reasonable, giving the employee a fair chance to address the concerns raised. While there is no strict legal timeframe set out in UK employment law, best practice suggests setting clear, realistic deadlines for review – often between two and four weeks, depending on the nature and seriousness of the issue. Employers should also ensure they comply with the principles of fairness outlined in the ACAS Code of Practice, which underpins all workplace disciplinary and grievance procedures.
This section forms part of the broader process of Writing a Letter of Concern to an Employee, which covers when and how to raise concerns, what to include in your letter, and how to handle follow-up steps. For employers seeking practical guidance on drafting such communications, a downloadable template for a letter of concern can be a helpful starting point – though it’s always wise to tailor the letter to the specific circumstances and seek HR advice if needed.
If you want to explore more about effective workplace communication and what should be included in employee letters, see our guidance on the Key Elements to Include in Employee Letters. Understanding the correct process and timelines can help ensure that both employers and employees are treated fairly, and that any issues are resolved constructively and in line with UK employment law.
When Should a Letter of Concern Be Issued?
When Should a Letter of Concern Be Issued?
Issuing a letter of concern is an important step in addressing issues such as underperformance, misconduct, or breaches of workplace policy. Ideally, a letter of concern should be sent as soon as reasonably possible after the issue is identified. Acting quickly ensures that the employee is made aware of the concern while the details are still fresh, giving them the best chance to understand the problem and take steps to improve.
Prompt action is not just good practice – it is also key to maintaining a fair and transparent workplace. Delaying the letter can make it harder for the employee to recall relevant events and may undermine trust between employer and employee. Addressing concerns early helps create an open dialogue and demonstrates that the employer is committed to resolving issues constructively.
Although there is no specific legal deadline for sending a letter of concern, best practice guidelines recommend that employers act without unnecessary delay. The Advisory, Conciliation and Arbitration Service (ACAS) Code of Practice on Disciplinary and Grievance Procedures advises employers to deal with issues promptly and consistently. This approach helps ensure that any actions taken are fair and reasonable, which is especially important if the matter later progresses to a formal disciplinary process.
Employers should also consider whether the concern could be resolved informally before issuing a formal letter. In some cases, a quiet conversation may be all that is needed. However, if the issue persists or is more serious, a written letter of concern provides a clear record and sets out expectations for improvement.
Timely communication demonstrates respect for the employee and supports a positive working environment. For more guidance on how concerns can be raised and managed effectively, see our section on Preparing to Raise Your Concern. Taking swift, fair action not only helps resolve issues but also shows a commitment to upholding workplace standards for everyone.
Typical Timelines for Employee Improvement
When an employee receives a letter of concern, employers in the UK typically set a clear timeframe for improvement. In most cases, this improvement period ranges from one to three months. The exact length depends on several factors, including the seriousness of the concern, the employee’s role, and the complexity of the issues involved.
For less serious matters – such as minor performance issues or breaches of company policy – a shorter improvement window (around four to six weeks) may be appropriate. For more complex or serious concerns, employers may allow up to three months, especially if the employee needs additional training or support to meet expectations.
It’s important to remember that these timeframes are not set by law, but are guided by principles of fairness and good practice, as recommended in the Acas Code of Practice on Disciplinary and Grievance Procedures. Employers should always consider what is reasonable in the circumstances and ensure that any deadlines are clearly communicated to the employee in writing.
Regular check-ins or review meetings are a vital part of the improvement process. These meetings – often held every two to four weeks – give both the employer and the employee a chance to discuss progress, address any ongoing issues, and clarify expectations. They also provide an opportunity to offer support, such as additional training or adjustments to workload, to help the employee succeed.
Clear communication is key throughout this period. The concern letter should set out:
- The specific areas needing improvement
- The standards expected
- The deadline for improvement
- The consequences if improvement is not made
Employers should ensure that employees understand what is required of them and what support is available. This not only helps the employee but also demonstrates that the employer is acting fairly and transparently, which is crucial if the process is later reviewed as part of a formal disciplinary action.

Factors Influencing Improvement Timelines
When deciding how long an employee should be given to improve after receiving a concern letter, employers must consider a range of factors to ensure the process is both fair and legally compliant. The appropriate timeline is rarely set in stone; instead, it should reflect the specific circumstances of the case and the needs of both the employee and the organisation.
Nature of the Issue
The type of concern raised in the letter is a key factor. For example, issues related to performance – such as not meeting targets or deadlines – may require a longer period for improvement than certain conduct issues, like repeated lateness or breaches of workplace rules. Health-related concerns, especially those connected to mental health, may also require more time and tailored support.
Employee’s Role and Responsibilities
The complexity of the employee’s role can influence how much time is reasonable for improvement. Senior staff or those in specialised positions may need a longer adjustment period due to the complexity of their duties. Conversely, for more straightforward roles, a shorter timeline might be appropriate. Employers should consider the impact of the issue on the wider team and business operations when setting expectations.
Previous History of Similar Issues
If the employee has previously been warned about similar concerns, this may justify a shorter timeframe for improvement. Repeated issues can indicate that prior support or warnings have not been effective. However, if this is the first time the concern has been raised, it is generally fair to allow a longer period for the employee to demonstrate improvement.
Support or Training Provided
Employers have a responsibility to provide reasonable support and training to help the employee address the concern. This may include coaching, mentoring, or formal training sessions. The amount and type of support offered can affect the improvement timeline – more complex interventions may require longer to show results. Employers should document all support provided, as this can be important if further action is needed.
For a deeper look at what employers can do to support staff and the steps involved in managing underperformance, see Additional Considerations.
Consideration of Mental Health or Personal Circumstances
Personal circumstances, such as health issues, family responsibilities, or mental health conditions, should always be taken into account. Employers have a legal duty to make reasonable adjustments under the Equality Act 2010 if an employee’s health or disability is impacting their performance or conduct. Timelines should be flexible enough to accommodate these needs, and communication should be sensitive and supportive.
To better understand your rights and the support available if mental health is a factor, visit Mental Health and Work: Your Rights.
By considering these factors carefully, employers can set realistic and fair improvement timelines that comply with UK employment law and best practice. This approach not only protects the rights of employees but also helps foster a more supportive and productive workplace.
What Happens After the Improvement Period?
After the agreed improvement period following a concern letter, both the employer and employee should meet to review the situation. There are several possible outcomes at this stage, depending on the employee’s progress and the nature of the original concern.
1. Satisfactory Improvement
If the employee has met the expectations set out in the concern letter, the employer should confirm this in writing. It is good practice to recognise the employee’s efforts and formally close the matter. Employers should keep a record of the improvement and the steps taken, in case similar issues arise in the future.
2. Some Progress, But Not Enough
If there has been partial improvement, the employer may consider extending the improvement period or providing additional support, such as further training or closer supervision. Any decision should be documented clearly, outlining what further improvement is needed and the new timescales. Employers should ensure that communication remains open and transparent, giving the employee a fair opportunity to succeed.
3. Insufficient or No Improvement
If the employee has not made sufficient progress, the employer may need to take further action. This could involve moving to a more formal stage of the disciplinary process, in line with the company’s policies and the Acas Code of Practice on Disciplinary and Grievance Procedures. At this point, the employer should:
- Clearly explain the reasons for further action;
- Provide evidence of the support and opportunities given to the employee;
- Set out the next steps, which may include a formal disciplinary hearing.
It is important that any decisions are based on documented evidence gathered throughout the improvement period. Employers should keep detailed records of meetings, communications, and any support offered.
4. Ongoing Communication and Fairness
Throughout the process, employers should maintain fair and transparent communication. Employees should always be given the chance to respond, ask questions, and, if appropriate, be accompanied at meetings. Following a fair process reduces the risk of legal challenges and demonstrates that the employer has acted reasonably.
For more guidance on handling similar workplace situations and understanding possible next steps, you may find it helpful to read about Work Grievance Meetings, which covers outcomes and what to expect after a formal meeting.
By following these steps, employers can ensure they manage concerns in a way that is consistent with UK employment law and best practice, supporting both the needs of the business and the rights of employees.
Legal Considerations and Best Practices
When dealing with employee concerns and timelines for improvement, it is crucial for employers to act in line with UK employment law and established best practices. Following the correct procedures not only ensures fairness for employees, but also protects employers from potential legal claims.
The Importance of Fair Procedures
Employers must handle concern letters and subsequent improvement periods in a way that is both transparent and consistent. This means following clear and fair processes, as outlined in the ACAS Code of Practice on Disciplinary and Grievance Procedures. The Code sets out the minimum standards for handling disciplinary matters, including the importance of giving employees adequate notice of concerns, clear expectations for improvement, and a reasonable timeframe to make those improvements.
Adhering to fair procedures is not just good practice – it is a legal requirement under the Employment Rights Act 1996. This Act outlines employees’ rights in the workplace, including protection against unfair dismissal. If an employer fails to follow a fair process or sets unrealistic improvement timelines, they risk facing claims of unfair dismissal or constructive dismissal.
Risks of Unfair Dismissal Claims
If an employee is dismissed without being given a fair chance to improve, or if the process is rushed or poorly documented, the dismissal may be deemed unfair by an employment tribunal. This can lead to costly legal disputes and reputational damage for the employer. To reduce this risk, employers should:
- Provide written documentation of the concern and any discussions.
- Set clear, achievable objectives for improvement.
- Allow a reasonable period for the employee to demonstrate progress.
- Offer support, such as additional training or mentoring, where appropriate.
For more on your legal obligations when communicating with employees, see Letters and Communications to Employees.
Record Keeping and Transparency
Maintaining accurate records throughout the process is essential. Keep copies of all correspondence, notes from meetings, and evidence of any support provided to the employee. This documentation can be vital if a dispute arises, as it demonstrates that the employer acted reasonably and followed the required procedures.
Equality and Discrimination Considerations
When setting timelines and expectations for improvement, employers must be mindful of their responsibilities under the Equality Act 2010. This legislation protects employees from discrimination on the grounds of age, disability, race, gender, religion, and other protected characteristics. Employers should ensure that improvement plans are tailored to individual needs where appropriate. For example, if an employee has a disability, reasonable adjustments may be needed to allow them a fair opportunity to improve.

Practical Tips for Employers
- Always provide clear reasons for concern and specify what improvement is required.
- Give employees sufficient time to respond and improve – what is “reasonable” may vary depending on the nature of the concern and the employee’s circumstances.
- Ensure all actions are consistent with your company’s policies and UK employment law.
- Seek guidance where needed, especially if equality or discrimination issues may arise.
By following these best practices and legal requirements, employers can support staff effectively, avoid legal pitfalls, and maintain a positive workplace culture.
Additional Resources and Support
If you are unsure about the process after receiving a letter of concern, or if you feel the procedure is not being handled fairly, it is important to know where to seek support and advice. Employees can often find helpful information and guidance through both internal and external resources.
First, you should consider raising your concerns directly with your employer. Many workplaces have clear procedures in place for discussing issues informally or formally. If you are not sure how to start, you may find it helpful to review the steps outlined in How to Raise Concerns at Work, which covers effective and legal ways to bring up workplace issues.
If you need further detail about the reasons and timing for raising concerns, the section Understanding When and Why to Raise Concerns at Work offers additional context and can help you understand your rights and responsibilities.
For independent and authoritative advice, the Advisory, Conciliation and Arbitration Service (Acas) provides practical guidance on workplace problems. Their resource, How to raise a concern at work, explains how to approach your employer, whether to raise issues informally or formally, and what to expect from the process. Acas also offers a confidential helpline if you have specific questions about your situation.
Remember, raising a problem formally is known as ‘raising a grievance’. While your employer cannot insist you do this, they may still need to investigate and take appropriate action if the issue is serious. Mediation is another option, where an impartial person helps both sides try to resolve the problem.
For employers, it’s equally important to follow fair procedures and seek guidance when needed. Making sure you address concerns promptly and transparently helps maintain trust and reduces the risk of legal disputes.
If you would like more information on these topics, or need help understanding your next steps, explore the resources above or speak to your HR department or a workplace representative. Taking early action and using the right support can often resolve concerns before they escalate.
