The Role of Line Managers in Fair Dismissal Procedures

Fair dismissal procedures are central to lawful termination of employment. In the UK, line managers are often the individuals responsible for initiating, conducting and managing disciplinary and performance processes that can lead to dismissal. Their actions directly influence whether a dismissal is fair in substance and process. Employment tribunals examine how managers handle these procedures when assessing claims such as unfair dismissal, wrongful dismissal and discrimination. This article explains the role of line managers in fair dismissal, relevant legal standards, key responsibilities, common risks and practical guidance for effective practice.

Fair Dismissal and Legal Framework

A dismissal is the ending of an employee's contract by the employer or with the employer's consent. For a dismissal to be fair, the employer must generally show a valid reason (such as conduct, capability or redundancy), and a fair and reasonable procedure was followed in reaching the dismissal decision. Failure to do so can lead to claims in the employment tribunal. Tribunal decisions take into account whether the employer's conduct was in line with recognised standards of fairness and reasonableness.

The Acas Code of Practice on Disciplinary and Grievance Procedures forms the benchmark for fair processes in disciplinary and dismissal situations. Although not legislation, tribunals will examine compliance and can increase or reduce compensation by up to 25 per cent for unreasonable failure to follow it.

Line Managers' Strategic Importance in Dismissal Procedures

First Line of Assessment and Investigation

Line managers are typically the first company representatives to identify performance or conduct concerns. They must assess whether informal resolution is possible or whether formal processes should begin. Best practice encourages early discussion to clarify issues, set expectations and document concerns. This can minimise escalation and improve outcomes for both the employee and employer.

Where formal action is required, managers often oversee initial fact‑gathering - collecting relevant documents, interviewing witnesses, and determining if there is a prima facie case for disciplinary action. Effective investigation supports the fairness of subsequent decisions and avoids procedural defects that tribunals scrutinise.

Adhering to Established Procedures and the Acas Code

The Acas Code sets out core principles of fairness, including timely communication, proper investigation, allowing the employee to put their case, permitting accompaniment at meetings, and enabling appeals. Line managers should be familiar with these principles and ensure the processes they oversee adhere to them.

Managers must:

• Inform the employee of the concerns and potential consequences in writing;
• Hold a disciplinary meeting where the employee can respond;
• Consider the evidence impartially before deciding;
• Communicate decisions in writing, citing reasons and appeal rights; and
• Facilitate the appeal process in line with policy and statutory rights.

Responsibilities at Each Stage

Informal Discussions and Early Management

Before formal action, many issues can be resolved through informal discussion. This may involve clarifying performance expectations and agreeing improvement plans. Early, constructive conversations can prevent misunderstandings and build mutual trust.

Formal Investigation

In more serious cases, a formal investigation determines whether there is sufficient evidence to justify disciplinary proceedings. Line managers may lead or support this work, ensuring that investigations are thorough, unbiased and documented. This evidence becomes critical if a dismissal decision is challenged at an employment tribunal.

Disciplinary Meetings

During disciplinary meetings, managers must explain the allegations, allow the employee to respond, and consider any mitigation. Employees have the right to be accompanied by a colleague or trade union representative at formal meetings. Line managers should understand this right and facilitate it.

Decision‑Making and Authority

While line managers initiate procedures, organisations often require that final decisions to dismiss be made by someone sufficiently senior or independent of the investigation. Wrigleys' employment guidance recommends that investigation, decision‑making and appeal stages be conducted by different managers where possible to avoid bias and preserve fairness.

Reducing Legal Risks Through Fair Practice

Procedural Consistency

Procedural fairness reduces the risk of tribunal claims. Managers should apply rules consistently across similar cases. Employers should train line managers in the legal and practical implications of dismissal processes and disciplinary procedures so they understand the implications of their conduct.

Documentation and Transparency

Detailed records of meetings, correspondence, performance reviews and decisions are essential. These records support the employer's position if challenged and show that the manager acted reasonably and transparently.

Consideration of Alternatives Before Dismissal

Line managers must explore alternatives to dismissal, such as training, mediation, role changes, performance improvement plans or informal warnings. Tribunals assess whether dismissal was a proportionate response after less severe options were considered.

Common Risks When Line Managers Fail to Follow Fair Procedures

Unfair dismissal claims: If procedures are flawed - for example, no proper investigation or failure to allow response - tribunals may find dismissal unfair, even if the substantive reason (conduct or capability) could have justified dismissal.

Compensation uplifts: A tribunal may increase compensation by up to 25% if it finds the employer unreasonably failed to follow the Acas Code's procedural guidance.

Discrimination or unrelated claims: Poorly handled dismissals can also give rise to discrimination claims if a manager's conduct disproportionately affects employees with protected characteristics.

Practical Guidance for Managers

Training and Awareness

Managers should receive periodic training covering:

• legal standards on dismissal and discipline;
• procedural rights under the Acas Code;
• how to conduct interviews and meetings fairly; and
• documentation requirements.

Working with HR or Legal Advisors

In complex cases, line managers should work with HR or legal advisors to ensure that procedures reflect organisational policy and statutory requirements. Professional input can prevent errors that lead to costly tribunal claims.

Communication and Respect

Clear, respectful communication helps maintain dignity in difficult situations. Managers should explain procedures, listen actively, and treat employees consistently and reasonably throughout the process.

Common Questions from our Readers

Can a line manager dismiss someone without involving HR?
In many organisations, dismissal decisions require HR oversight or senior approval. Even where line managers lead procedures, a formal decision must align with policy and legal requirements - and consulting HR reduces risk.

Is failure to follow the Acas Code automatically unfair?
Not automatically. However, tribunals take the Code into account and can adjust compensation if they find unreasonable failure to comply.

Do line managers need legal training for dismissals?
While not legally required, training in employment law fundamentals and organisational procedures equips managers to make fair decisions and reduces the risk of tribunal claims.

Final Thoughts

Line managers play a central role in fair dismissal procedures in England and Wales. They often initiate investigations, manage disciplinary meetings and ensure that procedural standards are met. Compliance with the Acas Code on disciplinary and grievance procedures, clear documentation, consistent application of rules and exploration of alternatives to dismissal all contribute to fairness and reduce legal risk. By understanding their responsibilities and engaging with HR and legal advisors, managers can ensure that dismissal decisions are made lawfully, reasonably and with respect for employment rights.
