Common ways employers get grievances wrong

If your grievanceA formal complaint raised by an employee against their employer, triggering a legal obligation to investigate and respond. is being handled badly, you’re not imagining it. There’s a name for most of what employers get wrong, and knowing which failure you’re looking at helps you work out what to do next and what it might mean for your position.

This isn’t a guide to raising a grievance for the first time. That’s covered in the complete guide to raising a grievance at work. This is about what happens when the process itself breaks down: the ways employers commonly fail at handling a grievance once it’s been raised, and what each failure actually means for you legally, not just how it feels.

None of these failures are rare. They show up again and again in tribunal decisions, which is exactly why each one below is anchored to a real case rather than general advice. If you recognise your own situation in one of these, that’s not a coincidence. It’s a pattern that’s been tested and named before.

The six failures at a glance

No real investigation: a decision letter that restates your complaint but never mentions a witness, a record, or a conflicting account being checked. (Bracebridge Engineering v Darby)

Refusing to hear it at all: “outside the policy,” “connected to a disciplinary process,” “not the right time,” or a missed deadline you were never told about. (Goolds v McConnell, Dr S Stothard v Durham University)

Rejected on a technicality: told your complaint “wasn’t a proper grievance” because of its wording or format, not its substance. (Shergold v Fieldway Medical Centre)

Appeal isn’t independent: the same manager who rejected your grievance also hears, and rejects, your appeal. (Blackburn v Aldi Stores Ltd)

Discrimination grievance waved through: a complaint that raises discrimination or harassmentUnwanted behaviour related to a protected characteristic, such as your sex, race, disability, age or religion, that violates your dignity or creates an intimidating, hostile or humiliating environment... gets no real look, often dismissed on the same policy technicalities as above. (Iwuchukwu v City Hospitals Sunderland)

Complaint about the complaint ignored: a second grievance, about how the first was handled, gets refused or ignored in turn. (Dr S Stothard v Durham University)

Use this as a quick way to check where you stand before reading the full detail below. Most real situations involve more than one of these at once, and that combination usually matters more to a tribunal than any single failure on its own.

Your employer never really investigated

A grievance that gets a decision without a real investigation isn’t a grievance that’s been handled. It’s a grievance that’s been dismissed while looking like it wasn’t.

A real investigation has a shape to it. Someone speaks to you in enough detail to understand what happened. Someone speaks to any witnesses you’ve named, and often to others who might reasonably know something. Relevant records get checked too. Emails. Rotas. Incident logs. Anything that actually exists. Where your account and someone else’s account conflict, someone actually weighs the two against each other rather than picking a side by default. If none of that happened before your grievance was decided, it wasn’t investigated. It was rubber-stamped.

This matters for more than fairness. A single serious incident of harassment can be enough on its own to found a claim. It doesn’t need a pattern of repeated behaviour behind it. An employer who fails to investigate it properly then compounds the original wrong instead of resolving it. The failure to investigate becomes part of the story, not a footnote to it.

A single act of harassment can be serious enough to justify leaving your job.

Your employer refuses to hear it at all

Sometimes a grievance doesn’t get investigated badly. It doesn’t get heard at all.

Employers lean on a small number of recurring excuses here. The complaint “falls outside the grievance policy.” It’s “connected to a disciplinary process already underway.” Something else is apparently going on, so now supposedly isn’t the moment. Or it was raised “too late,” against some internal deadline nobody ever actually told you about.

You have an implied right, built into every employment contract whether it’s written down anywhere or not, to have a genuine grievance reasonably and promptly considered. This is not a policy courtesy. It’s a term of your contract, and an employer can’t get around it just by defining your complaint out of scope on paper.

The “connected to a disciplinary process” excuse deserves particular attention, because it’s frequently stretched further than it should go. A policy exclusion for grievances about a disciplinary outcome is meant to stop you re-litigating a decision you’ve already had the chance to appeal through the disciplinary process itself. It is not meant to block a grievance about being suspended in the first place, or about how an investigation into you is being conducted while it’s still live. Those are different questions, and an employer who refuses to hear either on the grounds that “there’s already a process running” is usually reading their own policy more broadly than it was ever intended to be read.

If your employer refuses to engage with a grievance, that refusal is not neutral. It’s a decision, and a tribunal can weigh it later, particularly where the refusal is one of several things that go wrong, or where things go on to end in resignation. A pattern matters more than one isolated refusal. This is especially true where a second complaint is about how the first one was handled.

Your employer has an implied legal obligation to give you a proper opportunity to raise and resolve grievances at work.

Your grievance gets rejected on a technicality

Some employers reject a complaint because it wasn’t labelled correctly, or didn’t use the word “grievance.” Others reject it because it didn’t follow the exact format their policy describes. This doesn’t hold up the way employers sometimes assume it does.

A written complaint can count as a valid grievance even if you never called it one. What matters is substance, not form: you put your concern in writing, and your employer could reasonably understand what you were unhappy about from what you wrote. You don’t need to cite the policy. You don’t need to say you’re “invoking the grievance procedureThe formal process your employer must have in place for you to raise a complaint about your treatment at work. It should set out the steps involved, including who to write to, timescales for a respons....” You don’t need to list every incident with forensic precision either. Even a resignation letter can count as a valid grievance in its own right, if what it describes matches what you’re later complaining about.

This also cuts the other way in a useful sense. If you’ve already raised a grievance about an ongoing course of treatment, you’re not required to raise a fresh, separate grievance every single time the same underlying problem repeats itself. Once the pattern has been flagged, later incidents of the same kind can usually be treated as part of what you already raised, rather than something you needed to formally re-report each time.

If your employer tells you a complaint doesn’t count because of its form rather than its substance, that argument is generally weaker than it sounds, and worth pushing back on rather than accepting at face value.

A written complaint can count as a grievance even without the right wording

Your appeal isn’t really independent

An appeal heard by the same manager who rejected your original grievance is not an appeal. It’s the same decision, made twice, with a different label on the second occasion.

Genuine independence means the person hearing your appeal had no role in the original decision. They didn’t investigate it. They didn’t decide it. Ideally, they weren’t closely involved in the underlying events either. In practice this usually means someone at the next level of management up, not a peer of the original decision-maker and not the same person wearing a different hat.

You’re entitled to an appeal that meets that bar. It’s a right, not a courtesy. A tribunal can treat a same-manager appeal as capable of breaching your employer’s basic contractual obligations toward you, on top of, or even independently of, whatever the substance of your original complaint was. That matters because it means a same-manager appeal can be a live issue even in a case where your original grievance was genuinely a close call on the facts. The independence of the appeal is judged on its own terms, not treated as harmless just because the underlying decision might have gone the same way either way.

Small organisations sometimes argue there was no one else senior enough to hear the appeal. That can be a genuine constraint, but it isn’t a free pass: where a truly independent option exists, even an external one, an employer who defaults to the same manager anyway because it’s easier is taking a real risk.

A grievance appeal by the same manager who rejected it is not independent.

Your discrimination grievance gets waved through without a proper look

This deserves its own section, separate from the general “never really investigated” failure above, because the legal consequences are different and more serious.

Discrimination, harassment connected to a protected characteristicOne of the nine characteristics listed in the Equality Act 2010 against which it is unlawful to discriminate. They include age, disability, race, sex, religion or belief, and sexual orientation. If yo..., and victimisationBeing treated badly because you've raised a complaint, supported someone else's complaint, or done something else the law protects, such as raising a grievance or whistleblowing. It is unlawful in its... deserve special attention here. If your grievance raises any of these and your employer fails to investigate it properly, that failure isn’t just a process defect. It can itself amount to a fresh, separate act of discrimination or victimisation under the Equality Act 2010The main piece of legislation protecting employees from discrimination at work. It covers nine protected characteristics including age, disability, sex, race, and religion, and makes it unlawful for a..., on top of whatever the original treatment you complained about was.

This holds even where your employer points to a policy technicality, a missed internal deadline, say. It holds especially where that same deadline hasn’t been applied consistently to other complaints.

The practical effect is that ignoring a discrimination grievance carries its own distinct legal exposure for your employer, separate from and in addition to the underlying issue. You don’t need the original complaint to ultimately succeed for the failure to investigate it properly to matter in its own right.

If your grievance touches on discrimination in any way and you feel it’s being brushed aside, be explicit in writing that discrimination is part of what you’re raising. This isn’t about using the word as a threat. It’s about making sure the nature of your complaint is genuinely on the record, so a later failure to engage with it can be assessed for what it actually is.

Not investigating your discrimination grievance can itself be discrimination

Your complaint about the grievance process gets ignored too

Sometimes the original complaint isn’t where things go wrong. What happens next is. If you raise a further grievance about how your first one was handled, badly, dismissively, or not at all, and that second complaint gets refused or ignored as well, that’s not a smaller, secondary issue sitting underneath the first one. It compounds it.

Employers sometimes read policy exclusions too broadly here as well, treating a complaint about the process itself as somehow out of scope because it relates to a matter that’s technically still open. The same principle from the “refuses to hear it at all” section applies: a narrow exclusion meant to cover one specific thing cannot be stretched to swallow a genuine complaint about how you’re actually being treated along the way.

Where this happens, it tends to be read together with the underlying grievance and any other failures around it, rather than in isolation, when a tribunal is assessing whether things have added up to a fundamental breach of your contract.

Why this keeps happening

Most of these failures aren’t deliberate cruelty. They’re pressure and habit. A manager too stretched to investigate properly. A small team with nobody obviously independent to hear an appeal. A policy nobody’s reread since it was written. Plain discomfort at looking closely into something uncomfortable.

This kind of pressure is not an excuse. Your legal position stays the same regardless. But it does mean something practical: clear, calm, written pushback tends to work. Name the specific failure, in writing, at the time it happens. That gives your employer a real chance to correct course, and it protects your position if they don’t.

What a grievance outcome letter reveals

You don’t need to be able to prove any of the six failures above from first principles. Often, the outcome letter itself is the clearest evidence of which of them happened, if any. Look past the conclusion. Check what the letter actually covers, and what it skips.

Below are two composite examples, built to illustrate the pattern rather than drawn from any single case. Compare them against a letter you’ve actually received.

A weak outcome letter looks like this:

Thank you for raising your concerns about your treatment by your manager. Having reviewed your grievance, we do not uphold your complaint. We consider the matter closed. If you wish to appeal, please contact [manager’s name], who will hear your appeal.

This is short for a reason, and the reason is rarely a good one. Nobody being spoken to. No record being checked. No conflicting account weighed against another. That absence is the first sign no real investigation happened. “We consider the matter closed” is a conclusion with nothing underneath it: no reasoning you can actually test or push back on. And the appeal contact named at the end is the same manager who made the original decision, meaning the “appeal” on offer isn’t independent at all.

A stronger outcome letter looks like this:

As part of investigating your grievance, we spoke with you, with [two named witnesses], and reviewed the rota and incident log covering the relevant period. Where your account and [the other party’s] differed on [the specific point], we have set out below why we preferred one version over the other, and what led us to that view. Your grievance is not upheld, for the following reasons: [reasoning specific to your complaint]. You have the right to appeal this decision. Your appeal will be heard by [named manager with no prior involvement in this grievance].

This letter can still reject your grievance. It can still be a properly handled one. A real investigation doesn’t guarantee an outcome in your favour. What it guarantees is that someone actually did the work. They named who was spoken to. They named what was checked. Where accounts conflicted, they explained why, rather than just announcing a winner. And they routed the appeal to someone genuinely new to the matter. Every one of those details is visible on the face of the letter, which is exactly why it’s worth reading your own outcome letter as closely as you’d read a contract.

What to do if you recognise your situation

Start documenting things now, in writing, as they happen, rather than trying to reconstruct a timeline later from memory. Note dates, who was involved, what was said, and what wasn’t said or done. A grievance decision letter that never mentions speaking to a witness is evidence in itself; keep a copy.

If you think one of these failures applies to you, say so in writing, plainly and without needing legal language. You don’t have to prove your case at this stage. You just need a clear, contemporaneous record that you raised the specific concern. Maybe that’s a lack of real investigation. Maybe it’s a refusal to hear your grievance, an appeal that wasn’t independent, or a discrimination complaint nobody took seriously.

If your own outcome letter reads like the weak example above, write back. Ask specifically what was investigated, who was spoken to, and who is independent enough to hear your appeal. Keep a copy of both letters.

If your employer’s failures are severe enough, taken together, or have gone on for long enough, you may be looking at a constructive dismissalWhen your employer's behaviour is so serious that you feel you have no choice but to resign, the law may treat that resignation as a dismissal. The most common basis is a fundamental breach of the imp... question rather than just a badly handled grievance. That is a different and much higher-stakes decision, because resigning is not something you can undo afterwards. Thinking about resigning because of how you’ve been treated? Read this first. covers what to weigh before you get anywhere near that point.

Whatever stage you’re at, get advice before you take any step that can’t be reversed, and particularly before you resign. A badly handled grievance is a real problem, and the law gives you more protection here than most employees realise. What you do next is the part that’s genuinely hardest to take back once it’s done.
