What Is a Disciplinary Procedure? A No-Nonsense Guide for Employers

I've lost count of the number of times a client has called me in a mild panic because someone's turned up late for the fourth time that month, or missed a deadline that mattered, and their instinct is to march the person into an office and sack them on the spot. I get it. When something's frustrating you, the temptation is to deal with it fast and be done with it. But fast and fair rarely live in the same sentence, and skipping the process is how a straightforward performance issue turns into a five-figure tribunal claim.

So let's talk about what a disciplinary procedure actually is, because I think the phrase itself puts people off. It sounds punitive but it isn't meant to be. A good disciplinary procedure is a structured, fair way of dealing with conduct or performance concerns and resetting the standard of expectations.  Structure is what protects you.

Why you can't just wing it

Under UK employment law, if you dismiss someone (or take other disciplinary action) without following a fair process, you're exposed, even if the underlying reason for the action was perfectly sound. A great example of this was the case of an administrator who was sacked for insulting a customer in an email but won a payout of almost £5,500 after claiming unfair dismissal.

Meliesha Jones, was dismissed by her employer when she called a customer a t**t in an email and mistakenly sent it to him instead of a colleague.  This was a case that would have met the definition of gross misconduct but the tribunal held that the procedure followed by the employer in this case was a ‘sham’ designed to placate the customer, and, had a fair procedure been followed, there was no chance that the claimant would have been dismissed.  Tribunals don't just look at whether you were "right" to be unhappy with someone. They look at how you got there.

That's where the Acas Code of Practice on Disciplinary and Grievance Procedures comes in. It's not itself the law, but tribunals refer to it constantly, and if you've ignored it unreasonably, they can increase any award against you by up to 25%. That's not a footnote. That's a genuinely painful number if things go wrong.

The bones of a fair procedure

Strip away the jargon and a fair disciplinary process comes down to a handful of steps, done properly and in order:

1. Establish the facts first. 

Before you write a single letter, find out what actually happened. Sometimes that's a quick conversation. Sometimes it needs a proper investigation with witness statements and evidence gathered. Skipping this step is the single most common mistake I see people decide the outcome before they've even asked the questions.

2. Tell the employee, in writing, what the issue is.

Not vaguely. Specifically. They need enough detail to actually prepare a response, not a one-line email that leaves them guessing.  Don’t send this at 5pm on a Friday.

 3. Hold a meeting.

Give reasonable notice. Let them bring a colleague or trade union rep; this is a legal right, not a nice-to-have. Listen. Actually listen, not just wait for your turn to speak.

4. Decide, and explain the decision.

The outcome should be proportionate to what actually happened, not to how annoyed you were on the day you found out about it.

5. Give them the right to appeal.

Ideally to someone who wasn't involved in the original decision. If your business is small enough that this genuinely isn't possible, do your best; a fresh pair of eyes, even from within the same small team, is better than none.

The bit people underestimate

Here's what I'd add that doesn't always make it into the standard guides: consistency matters as much as process. If you've let three people off with a warning for the same thing and then dismiss the fourth, you've got a problem; even if you followed every procedural step to the letter. A previous employer of mine once said to me ‘some people deserve 9 nine lives and some people don’t’.  This is problematic.  Keep records. Not because you're building a case against anyone, but because in six months' time you won't remember exactly what you agreed, and neither will they.

Where this gets genuinely difficult

Straightforward misconduct; someone’s stolen from the till, someone's been abusive to a colleague, is, relatively speaking, the easy end of this. The harder conversations are the ones where there's more going on underneath: a performance dip that might be linked to a health condition, a pattern of lateness that might be linked to caring responsibilities, conduct that might be linked to something the person hasn't disclosed yet. This is where I think a lot of standard disciplinary guidance falls short, it treats every case as a clean line from behaviour to consequence, when in practice the line is rarely that clean.

The short version

A disciplinary procedure isn't a weapon and it isn't paperwork for paperwork's sake. It's the thing that lets you make a fair decision, defend that decision if you're ever challenged on it, and, just as importantly, actually get to the right outcome instead of the fastest one. Slow down at the start so you don't have to slow down later, in a tribunal, explaining yourself to someone who's paid to find the gaps in what you did. 

If you're staring down a situation right now and you're not sure whether it needs a quiet word or a formal process, that's usually the first question worth asking someone who does this for a living before you write anything down.
