Most HR teams will know the broad shape of a disciplinary or grievance process. A concern is raised, the facts are investigated, people are given the opportunity to explain their side and, eventually, a decision is reached.
On paper, that all sounds pretty straightforward. In practice, keeping the process fair and consistent can be harder - particularly when a case involves multiple people, pieces of evidence and decisions made over weeks or months.
That’s where the Acas Code of Practice comes in. It sets out the basic principles employers should follow when handling disciplinary and grievance cases fairly, from establishing the facts through to giving employees the opportunity to appeal. And it isn’t something employers can afford to just treat as a box-ticking exercise. Employment tribunals take the Code into account in relevant cases, and awards can be adjusted by up to 25% where an employer or employee unreasonably fails to follow it.
But having a good understanding of the procedure is only part of the job. HR teams also need to make it work consistently across real cases - keeping evidence together, making sure the right actions happen at the right time and maintaining a clear record of how each decision was reached.
So, what does that look like in practice?
Disciplinary issues usually start with a concern about someone’s conduct or performance. Performance problems might be handled separately through a capability process, depending on the organisation. But where a formal disciplinary process is needed, Acas sets out what employers should do next.
Before anybody decides what should happen, they need to understand what actually happened.
Acas says employers should carry out any necessary investigation without unreasonable delay. Depending on the case, that might mean gathering documents, interviewing witnesses or holding an investigatory meeting with the employee. In misconduct cases, the person carrying out the investigation should ideally be different from the person who later conducts the disciplinary hearing.
This is often where a seemingly simple case starts to grow. One allegation can quickly turn into several interviews, multiple documents and different accounts of the same event. The challenge isn’t just gathering all that information. It’s keeping it organised enough that HR can see what has happened, what still needs to happen and who is responsible for it.
This is where having a dedicated case management system can make things much easier. Workpro brings evidence, correspondence, meeting notes and actions together in one case record, while task ownership, alerts and reminders help keep the investigation moving. A full audit trail also records what happened, who did it and when.
That means if the investigation changes hands halfway through, the next person doesn’t have to piece the story together from somebody else’s inbox.
If the investigation finds there is a disciplinary case to answer, the employee needs to know exactly what they’re being asked to respond to. The Code says they should be notified in writing and given enough information about the alleged misconduct or poor performance - and its possible consequences - to prepare for the meeting. Relevant written evidence should be shared too.
This can look like fairly routine admin, but it has a big effect on whether the process is fair. Was the allegation explained clearly? Was the right evidence included? Was the employee told when the meeting would take place and given reasonable time to prepare?
This is another area where putting structure around the process helps. Workpro’s HR configurable workflows can be built around an organisation’s own procedures and timelines, while templates, tasks and reminders help teams keep track of the communications and actions that need to happen along the way.
The point isn’t to automate the process for the sake of it. It’s to reduce the chance that an important step gets missed because someone was relying on memory.
The disciplinary meeting gives the employee a proper opportunity to respond before a decision is made.
The employer should explain the concern and go through the evidence that has been gathered, then the employee has the chance to answer the allegations, ask questions, present evidence and raise relevant points about any witness information.
That last part is really important. A disciplinary hearing shouldn’t simply confirm that a decision has already been made. Employers need to listen properly to what the employee says and be prepared to change course if new information comes to light.
Employees also have a statutory right to be accompanied at certain disciplinary meetings, including where the meeting could result in a formal warning or other disciplinary action.
Their companion can be a fellow worker, a trade union representative or an official employed by a trade union. Acas also covers what should happen if the chosen companion can’t attend at the proposed time, including circumstances where the hearing must be postponed.
For HR, the practical takeaway is fairly simple: those arrangements form part of the case too. If a meeting moves, a representative attends or correspondence is exchanged about the arrangements, there should be a clear record of it rather than details sitting across separate calendars and inboxes.
Once the meeting is complete, the employer needs to decide whether disciplinary action is justified.
Depending on the circumstances, that might mean no further action, a written warning, a final written warning or dismissal. And even where the alleged behaviour amounts to gross misconduct, Acas makes clear that a fair disciplinary process should still be followed before dismissal.
This is where consistency becomes particularly important. That doesn’t mean every case that looks similar on the surface should automatically have the same outcome. Different evidence, circumstances and mitigating factors can quite reasonably lead to different decisions. What matters is being able to explain why.
Having access to previous casework can help here. Rather than relying on someone remembering that “we had a similar case last year”, HR teams can look back at comparable cases and understand exactly how they were handled. Workpro makes casework fully searchable and allows cases to be tagged as linked or precedent cases, giving decision-makers useful context without taking the judgement out of their hands.
If the employee believes the action taken against them is wrong or unfair, they should be able to appeal. Acas says the appeal should be handled without unreasonable delay and, wherever possible, by somebody who hasn’t previously been involved in the case.
This is one of the points where good record-keeping really proves its value. The person handling the appeal may have had nothing to do with the original investigation. They still need to understand what was alleged, what evidence was gathered, what happened at the hearing and why the original decision was made. If all of that is captured in one case history, the handover becomes much easier. If it isn’t, someone has to rebuild the story before they can even begin reviewing the decision.
Acas also calls out a couple of situations that need additional care. If disciplinary action is being considered against a trade union representative, the normal procedure should still be followed, although it may be appropriate to involve an employed union official at an early stage with the employee’s agreement.
And if an employee is charged with or convicted of a criminal offence, that doesn’t automatically make it a disciplinary matter. The employer needs to consider what effect, if any, it has on the employee’s ability to do their job and their relationships at work.
Both are useful reminders that a fair process still needs human judgement. A workflow can guide the case, but it can’t decide the outcome.
Grievances start from a slightly different place. Instead of the employer raising a concern about someone’s conduct or performance, it’s the employee raising a concern, problem or complaint with their employer.
But many of the same things still matter. The employee needs a proper opportunity to explain what’s happened, the employer needs to look into it fairly, and there needs to be a clear record of how the final decision was reached.
So, what does that process actually involve?
Not every concern needs to become a formal grievance. Where possible, issues can often be resolved informally first. But if that doesn’t work, or the issue needs to be dealt with formally, Acas says the employee should raise their grievance in writing and without unreasonable delay. It should be raised with a manager who isn’t themselves the subject of the complaint.
That written grievance gives HR a starting point, but it probably won’t give them the whole picture. There might be supporting emails or documents to review, other people involved or parts of the complaint that need clarifying. Keeping all of that information connected from the beginning makes it much easier to follow the case as it develops.
The next step is to sit down with the employee and give them the chance to properly explain what’s happened and how they think the issue could be resolved. If something comes up that needs further investigation, the meeting can be adjourned while the employer looks into it.
The important thing is that the meeting is a genuine opportunity for the employee to be heard. They might raise something that wasn’t clear from their written grievance. Another person may need to be spoken to. New evidence might change how the situation looks. The process needs enough structure to keep things moving, but enough flexibility to follow the evidence wherever it leads.
Employees may also have a statutory right to be accompanied at a grievance meeting. Their companion can be a fellow worker, a trade union representative or an official employed by a trade union. Acas also sets out what should happen if their chosen companion can’t make the proposed meeting time.
It’s another detail that can sound fairly administrative until you’re actually managing the case. Meetings move, different people get involved and more correspondence is generated along the way. Keeping those details with the rest of the case means there’s a clear record of what happened rather than bits of the story living in different inboxes and calendars.
Once the meeting has taken place and any further investigation is complete, the employer needs to decide what to do.
Acas says the outcome should be confirmed in writing without unreasonable delay and, where appropriate, explain what action the employer intends to take to resolve the grievance. The employee should also be told that they can appeal if they’re unhappy with the outcome.
Just like with a disciplinary decision, it’s not enough for the record to simply say what the outcome was. Someone looking back at the case should be able to understand what information was considered, why the decision was reached and what happened next.
That becomes particularly important if the grievance ends up connecting to another process - for example, if what comes out of the investigation raises concerns about another employee’s conduct.
If the employee doesn’t feel their grievance has been satisfactorily resolved, they should be able to appeal. And this is another point where good record-keeping really matters.
Someone coming into the case at appeal stage needs to be able to see the full story: what the employee originally raised, what was investigated, what came out of the meeting and why the employer reached the decision it did. They shouldn’t have to reconstruct all of that from scratch.
Sometimes, the two processes can start to blur. How you handle them will depend on how closely the two issues are connected.
For example, an employee who is already going through a disciplinary process might raise a grievance. That grievance could relate directly to the disciplinary itself, someone involved in the process, or a separate but connected issue.
Acas says there are two ways the process may need to be handled:
There isn’t one approach that will be right for every case. HR needs to look at the circumstances, understand how the issues connect and decide what will be fairest and most practical.
This is where case management software like Workpro helps. It allows you to link related cases together so you have a complete view of both issues without cluttering individual records. Having that clear picture is vital because overlapping cases can quickly become complex, and the core goal remains the same: gather the facts, maintain accurate records, and ensure a fair outcome for everyone.
One final distinction is worth noting. Collective grievances - where a recognised trade union or other appropriate workplace representative raises a grievance on behalf of two or more employees - sit outside this process and should be handled under the organisation’s collective grievance procedure instead.
The Acas Code sets out what a fair process should look like. The harder part is keeping that process clear and consistent when real cases involve multiple people, documents and decisions.
Workpro brings that information together in one place, with configurable workflows, case records, task management, alerts, audit trails and reporting. The aim isn’t to replace human judgement, but to make the process around those decisions easier to manage, follow and evidence.
