Your Disciplinary Process Isn’t Protecting You. It’s Building the Case Against You.

Most businesses believe they have a disciplinary process that works. They have a policy in the handbook. They follow steps. There are letters, meetings, and outcome letters with dates on them. If asked, the HR team would say the process is ACAS-compliant, and they would probably believe it.

An employment lawyer acting for a dismissed employee would dismantle it in twenty minutes. Not because the process was absent, but because the process, as conducted, generated exactly the documentary evidence needed to prove that the outcome was predetermined, the investigation was inadequate, and the dismissal was procedurally unfair. The business did not fail to follow a process. It followed a process that methodically constructed the case against itself.

This is not an edge case. At Esbee, we see it consistently across mid-market businesses that believe their HR processes are sound. The gap between having a process and having a defensible process is where tribunal claims are won, and it is wider than most leadership teams realise.

The Investigation That Was Not an Investigation

The most common procedural failure in a disciplinary process is the investigation stage, and the most common form of that failure is an investigating officer who has already formed a conclusion before the first interview is conducted.

This happens for an understandable reason. In most mid-market businesses, the person assigned to investigate a disciplinary matter is a line manager who has direct knowledge of the situation, often the person who raised the concern in the first place. They know what happened, or believe they do. The investigation feels like a formality, a box to tick before moving to the hearing. So they conduct it accordingly: they interview the witnesses who support their account, they do not interview the ones who might complicate it, and they produce an investigation report that reads less like an impartial fact-finding exercise and more like a prosecution brief.

A tribunal will see through this instantly. The test is not whether an investigation was conducted, but whether it was reasonable. A reasonable investigation interviews witnesses on both sides. It gathers documentary evidence without selection bias. It is conducted by someone who does not have a personal stake in the outcome. It reaches no conclusion, because that is the hearing officer’s role, not the investigator’s.

The businesses that get this right are the ones that treat the investigation as a genuine exercise in establishing facts, assign it to someone who is not involved in the matter, and train their managers to understand the difference between investigating and building a case. The ones that get it wrong produce an investigation file that an employee’s solicitor will read with considerable professional satisfaction.

The Outcome Letter That Convicted You

After the hearing, the business issues an outcome letter. This letter is, in practice, the single most important document in any subsequent tribunal proceedings, because it is the business’s own contemporaneous record of its reasoning. If the reasoning is sound, the letter protects the employer. If it is not, the letter becomes the prosecution’s star witness.

The most common error in outcome letters is stating a conclusion without evidencing the reasoning that led to it. “Having considered all the evidence, I have decided that your conduct amounts to gross misconduct and I am dismissing you with immediate effect.” This tells the reader what was decided. It tells them nothing about why. It does not explain what evidence was considered, which evidence was preferred and why, what the employee’s responses were and how they were weighed, or what alternatives to dismissal were considered and why they were rejected.

A tribunal judge reading this letter will draw a specific inference: the decision-maker did not consider alternatives because the outcome was predetermined. That inference may be wrong. But the letter provides no evidence to rebut it, and in a tribunal, an assertion without evidence is not a defence. It is an invitation.

Esbee’s HR services team routinely reviews outcome letters before they are issued, for the straightforward reason that the cost of getting one wrong, in tribunal compensation, legal fees, and management distraction, dwarfs the cost of getting one right. The difference between a defensible outcome letter and a damaging one is not legal sophistication. It is the discipline of writing down, clearly and specifically, the reasoning that the decision-maker actually applied.

Following a process is not the same as following a defensible process. The gap between the two is where tribunal claims are won.

The Appeal That Made Everything Worse

The appeal stage is the last opportunity to correct a flawed process. It is also, in practice, the stage where most businesses compound the errors they have already made.

The ACAS Code of Practice on Disciplinary and Grievance Procedures is explicit: the appeal should be heard by someone who was not involved in the original decision. This is not a technicality. It is a fundamental requirement of procedural fairness, because an appeal heard by someone involved in the original decision is not an appeal. It is a review by someone who has already concluded that the decision was correct.

In mid-market businesses, particularly those without a deep management bench, finding someone uninvolved is genuinely difficult. The managing director was consulted informally before the decision. The operations director provided evidence to the investigation. The HR manager who advised on the process cannot hear the appeal because they are a witness to the procedure. The result is an appeal panel that includes someone who had prior involvement, and an appeal outcome that a tribunal will treat as procedurally unfair regardless of its merits.

The solution is not complicated, but it does require advance planning. Businesses need to identify, before a disciplinary situation arises, who in the organisation is capable of hearing an appeal, who is sufficiently senior to do so credibly, and how to insulate them from involvement in the original process. In some cases, the right answer is to bring in an external person to hear the appeal, someone with no prior involvement and no organisational loyalty to the original decision. This feels like an unusual step, but it is considerably less unusual, and considerably less expensive, than losing a tribunal because the appeal was compromised.

The Alternatives You Did Not Consider

Section 98 of the Employment Rights Act 1996 requires that a dismissal be fair in all the circumstances, and the band of reasonable responses test asks whether dismissal fell within the range of responses a reasonable employer could have adopted. What this means in practice is that a tribunal will examine whether the employer considered alternatives to dismissal and, if so, why they were rejected.

A final written warning instead of dismissal. Redeployment to a different role. A demotion with a structured improvement plan. Additional training or supervision. These are not creative suggestions. They are the alternatives that a tribunal expects a reasonable employer to have considered, and if the dismissal documentation shows no evidence that they were considered, the tribunal will infer that they were not.

This is particularly dangerous in cases that are not clear-cut gross misconduct. A long-serving employee with an otherwise clean record, a first offence that sits on the boundary between misconduct and gross misconduct, a situation where the employee’s personal circumstances may have contributed to the behaviour. In these cases, a reasonable employer does not proceed directly to summary dismissal. A reasonable employer considers the full range of options, documents that consideration, and explains in the outcome letter why dismissal was the proportionate response. The businesses that fail to do this are not necessarily making the wrong decision. They are making a potentially right decision in a way that is indefensible.

What This Actually Costs

The median award for unfair dismissal in the UK is not, in isolation, ruinous. But the median figure disguises the real cost to a mid-market business of getting a disciplinary process wrong.

Legal fees for defending a tribunal claim, even one that settles before hearing, typically run to £15,000 to £30,000. Management time consumed by the process, from initial response through disclosure, witness statements, and preparation for hearing, is conservatively two to three months of senior management attention spread across six to twelve months. The reputational cost, if the claim involves allegations of procedural unfairness, discrimination, or bad faith, is unquantifiable but real, particularly in sectors where talent acquisition depends on employer reputation.

Add the cost of a settlement that could have been avoided by a sound process, the cost of recruiting a replacement, and the cost of the organisational disruption that accompanies any contested exit, and the total cost of a single flawed disciplinary process is routinely £40,000 to £80,000. For a mid-market business, that is not a rounding error. It is the cost of a hire, a project, or a quarter’s marketing budget, consumed entirely by a process that was supposed to protect the business and instead exposed it.

An HR MOT will identify whether your disciplinary procedures, as currently documented and practised, would survive the scrutiny a tribunal applies. The cost of finding out in advance is a fraction of the cost of finding out in front of a judge.

The Uncomfortable Conclusion

The disciplinary process is one of the few areas of business management where the documentation you create during the process becomes the primary evidence used to assess whether the process was fair. Every letter, every note, every decision record is a document that will be read, in the event of a claim, by a legally trained professional whose job is to identify the gaps between what the process should have done and what it actually did.

Most businesses approach disciplinary processes as a management task with some HR overlay. The ones that handle them well approach them as an evidential exercise with a management purpose: every step designed not just to reach a fair outcome, but to create a contemporaneous record that demonstrates the outcome was fair.

The gap between these two approaches is not philosophical. It is financial. And the cost of closing it, through better training, better documentation, and better advice at the critical moments, is a fraction of the cost of discovering, in a tribunal, that the process you thought was protecting you was building the case against you.
