Disciplinary & Grievance.

A fair investigation is the foundation of a fair disciplinary process — its purpose is to establish the facts before any decision is made about whether disciplinary action is warranted. A reasonable investigation involves: gathering the relevant evidence, which may include documents, records, and statements from witnesses; interviewing the employee and any witnesses, keeping notes; and considering the evidence objectively and with an open mind. The investigation should be proportionate to the seriousness of the matter — a more serious allegation warrants a more thorough investigation. Importantly, the person who carries out the investigation should, where practical, be different from the person who conducts the disciplinary hearing and decides the outcome, to ensure fairness and avoid prejudgment. The standard expected is that the employer carried out as much investigation as was reasonable in the circumstances — not that it proved the matter to a criminal standard. A genuine belief in misconduct, held on reasonable grounds after a reasonable investigation, is the established framework for a fair conduct dismissal. We advise employers on conducting investigations that are thorough, fair, and properly documented.

Offering a right of appeal is an essential part of a fair disciplinary or grievance process, and is expected by the ACAS Code. After a disciplinary sanction or a grievance decision, the employee should be informed of their right to appeal, the time limit for doing so, and how to do it. If the employee appeals, the employer should: arrange an appeal hearing without unreasonable delay; where practical, have the appeal heard by someone who was not involved in the original decision and is more senior, to ensure a fresh and impartial consideration; allow the employee to be accompanied; consider the grounds of appeal genuinely; and communicate the outcome of the appeal in writing. The appeal may confirm, vary, or overturn the original decision. A properly conducted appeal is valuable because it can correct errors in the original process and can, in some cases, cure earlier procedural defects — strengthening the fairness of the overall process. Denying or mishandling an appeal, by contrast, can render an otherwise fair process unfair. We advise employers on handling appeals fairly and on who should hear them.

Handling disciplinary and grievance matters well protects a business in several ways. Most directly, a fair, consistent, and well-documented process is the best defence against employment claims: where a dismissal or decision is challenged, an employer that followed a proper process and can evidence it is in a far stronger position, and may avoid a finding of unfairness altogether. Following the ACAS Code protects against the uplift in compensation that applies where it is unreasonably ignored. Beyond the legal protection, handling these matters well supports good management: addressing conduct and performance issues fairly and promptly maintains standards and is fairer to other staff; taking grievances seriously resolves problems before they escalate and demonstrates that concerns will be heard; and consistent, transparent processes build trust and protect morale. Good process also protects the business's reputation, both internally and externally. In short, investing in sound disciplinary and grievance handling — clear procedures, trained managers, and access to advice when needed — reduces legal risk, improves management, and protects the working environment. We help employers put these foundations in place and support them when issues arise.

Handling a disciplinary issue fairly means getting both the substance and the procedure right. The essential elements of a fair disciplinary process are: establishing the facts through a reasonable investigation before any decision is made; informing the employee in writing of the allegations and the possible consequences; holding a disciplinary hearing at which the employee can respond to the allegations and put their case, accompanied if they wish; reaching a decision based on the evidence and applying a sanction that is reasonable in the circumstances; confirming the outcome and the reasons in writing; and offering the right of appeal. Throughout, the employer should act consistently, keep an open mind until the hearing is complete, and document each step. Following a fair process matters not only because it is the right thing to do, but because an unfair process can make a dismissal unfair even where the underlying concern was justified. The ACAS Code of Practice sets the standard that tribunals expect employers to follow. We guide employers through disciplinary processes to ensure they are fair, consistent, and defensible.

A grievance is a concern, problem, or complaint raised by an employee, and handling it properly is both good practice and a legal expectation under the ACAS Code. A fair grievance process involves: encouraging the employee to set out their grievance, usually in writing; investigating the matter where necessary to understand the facts; holding a grievance meeting at which the employee can explain their concern and what they would like to happen, accompanied if they wish; considering the grievance genuinely and reaching a reasoned decision; confirming the outcome and the reasons in writing; and offering the right to appeal if the employee is dissatisfied. Grievances should be dealt with promptly and taken seriously, even where the employer doubts their merit — dismissing a grievance without proper consideration can escalate the matter, damage trust, and form the basis of a later claim, including constructive dismissal. Handling grievances well can resolve problems before they become disputes. We advise employers on handling grievances fairly and on the steps to take where a grievance raises serious or sensitive issues.

At a disciplinary hearing, the employee has important rights that the employer must respect for the process to be fair. The employer should: inform the employee in advance, in writing, of the allegations against them and the possible consequences, including where dismissal is a possibility; provide the employee with the evidence to be relied on, in good time before the hearing, so they can prepare their response; hold the hearing without unreasonable delay but allowing reasonable time to prepare; and give the employee a genuine opportunity at the hearing to respond to the allegations, present their case, and put forward any mitigation. The employee has a statutory right to be accompanied at the hearing by a colleague or a trade union representative, and the employer should remind them of this right. The employer should keep an open mind, listen to what the employee says, and only reach a decision after the hearing. Failing to provide these rights — particularly failing to share the evidence or denying the right to be accompanied — can render a dismissal unfair. We advise employers on conducting hearings fairly.

Getting a disciplinary or grievance process wrong carries significant risk for an employer. The principal risk arises on dismissal: even where there was a genuine reason to dismiss, a flawed process can make the dismissal unfair, exposing the business to an unfair dismissal claim and compensation. Common procedural failures include inadequate investigation, failing to share evidence, denying the right to be accompanied, prejudging the outcome, imposing an inconsistent or disproportionate sanction, and failing to offer a fair appeal. Unreasonable failure to follow the ACAS Code can increase compensation by up to 25%. Mishandling a grievance can also lead to claims, including constructive dismissal where an employee resigns in response to the employer's failure to address a serious concern. Beyond the legal exposure, poorly handled processes damage trust, morale, and the working environment. Most of these risks are avoidable with a fair, consistent, and well-documented process. Because the consequences of getting it wrong can be costly, taking advice — particularly before dismissing or in serious or sensitive cases — is a sound investment. We help employers run processes that minimise these risks.

The disciplinary sanctions available to an employer typically range from informal action, through formal warnings (such as a first written warning and a final written warning), to dismissal. The sanction imposed must be reasonable and proportionate to the misconduct or issue, taking account of the circumstances, the employee's record, and how similar cases have been treated. Dismissal is the most serious sanction and is justified only where it falls within the band of reasonable responses open to a reasonable employer in the circumstances — the test a tribunal applies. Dismissal may be justified for a serious first offence amounting to gross misconduct (such as theft, violence, or a serious breach of trust), which can warrant summary dismissal without notice, or where misconduct or poor performance has continued despite warnings. Consistency is important: imposing a markedly harsher sanction than in comparable cases, without good reason, can render a dismissal unfair. The employer must also have followed a fair process. We advise employers on the appropriate sanction and on whether dismissal is justified and defensible in the circumstances.

The ACAS Code of Practice on Disciplinary and Grievance Procedures sets out the standards of fairness that employers are expected to follow when handling disciplinary and grievance matters. In essence, it requires employers to: deal with issues promptly and consistently; carry out a reasonable investigation to establish the facts; inform employees of the problem and give them an opportunity to put their case at a meeting before any decision is taken; allow employees to be accompanied at formal meetings; and provide a right of appeal. The Code matters enormously for employers because of its legal consequences: while a failure to follow the Code does not by itself make a dismissal automatically unfair, tribunals take compliance into account when deciding whether a dismissal was fair, and — critically — a tribunal can increase a successful claimant's compensation by up to 25% where the employer has unreasonably failed to follow the Code. Conversely, compensation can be reduced by up to 25% where the employee unreasonably failed to follow it. Following the Code is therefore both good practice and an important protection. We ensure employers' processes comply with the Code.

It is common for a disciplinary matter and a grievance to arise at the same time — for example, where an employee facing disciplinary action raises a grievance about the process, about the person handling it, or about related treatment. Handling overlapping matters requires care. The ACAS Code recognises that where an employee raises a grievance during a disciplinary process, it may sometimes be appropriate to pause the disciplinary process temporarily to deal with the grievance, particularly where the grievance relates to the disciplinary matter itself — for instance, an allegation of bias or unfair treatment. In other cases, where the grievance is unrelated, it may be appropriate to deal with both concurrently, or to deal with them through the same process. The right approach depends on the nature and relationship of the two matters. What matters is that the employer deals with both fairly and does not use one to avoid properly addressing the other. Mishandling overlapping matters is a common source of unfairness. Because the right approach is fact-sensitive, taking advice helps ensure both are handled correctly. We guide employers through overlapping disciplinary and grievance situations.

Keeping proper records of disciplinary and grievance matters is essential — both for good management and as protection if a matter is later challenged at tribunal. Records should be kept at each stage and typically include: notes of the investigation, including witness statements and evidence gathered; copies of the correspondence informing the employee of allegations or acknowledging a grievance; notes or minutes of any investigation, disciplinary, grievance, and appeal meetings; the decisions taken and the reasons for them, as confirmed to the employee in writing; and a record of any sanction imposed and its duration. Contemporaneous records — made at the time rather than reconstructed later — are particularly valuable, as they are far more persuasive evidence of what happened and why. Records must be kept securely and in compliance with data protection law, and retained for an appropriate period. Good record-keeping demonstrates that a fair process was followed, which is often decisive if a dismissal or other decision is challenged. We advise employers on what to record and on retaining records appropriately.

Not every issue requires a formal disciplinary process, and knowing when to use one is part of handling matters well. Minor issues — such as occasional lateness, minor performance dips, or one-off lapses — can often be dealt with informally in the first instance, through a quiet word, informal guidance, or coaching, which is frequently more effective and proportionate. A formal disciplinary process is appropriate where: the issue is more serious; informal measures have not resolved a recurring problem; or the matter could lead to a formal sanction such as a warning or dismissal. Using a sledgehammer for a minor issue can damage relationships and morale, while failing to address a serious issue formally can allow problems to escalate and undermine any later action. The key is to respond proportionately to the seriousness of the issue, and to be consistent in how similar issues are treated across the workforce. Where there is doubt about whether a matter warrants formal action, taking advice helps ensure a proportionate and consistent response. We advise employers on when formal action is appropriate and how to handle matters proportionately.
