Grievance Procedures for Teachers Explained

The short answer

What actually counts as a grievance

A grievance, in the employment-law sense, is a concern, problem or complaint you raise with your employer about something affecting you at work. In a school context, the concerns that most commonly become formal grievances include an unmanageable or unfairly allocated workload, bullying or harassment by a colleague or line manager, unfair treatment over pay, an allowance or a TLR, discrimination connected to a protected characteristic, an unaddressed health and safety concern, or a suspected breach of your contract.

Not every workplace problem is a grievance, and raising the wrong process can slow things down. If your real concern is another staff member's conduct, or that a child may be at risk, the more appropriate route is usually a concern or a safeguarding referral to your designated safeguarding lead, rather than a personal grievance about how it affected you. The two aren't mutually exclusive — you can raise both, separately. Working out which category applies, ideally with your union representative, is worth doing before you put anything in writing.

The Acas Code: why it has real legal weight

The single most useful thing to understand before raising a grievance is that you're not simply relying on your school's goodwill. The Acas Code of Practice on disciplinary and grievance procedures is a statutory Code of Practice, approved by Parliament, and it applies to every employer in Great Britain — maintained schools, academies and trusts included — whether or not their own policy mentions it by name.

That status carries a concrete consequence. Section 207A of the Trade Union and Labour Relations (Consolidation) Act 1992 lets a tribunal increase compensation by up to 25% where an employer unreasonably failed to follow the Acas Code — and reduce it by up to 25% where the employee failed to follow it. Few grievances reach a tribunal, but it gives a well-advised employer real reason to run your grievance fairly, and gives you reason to engage properly yourself rather than disengaging out of frustration.

Step-by-step: the formal grievance procedure

Employer policies vary in their exact wording, but the large majority of school and trust grievance procedures follow a structure directly modelled on the Acas Code. Here's what that typically looks like in practice, stage by stage.

Whose policy actually applies to you

It's worth being upfront: there is no single, universal grievance procedure that applies to every teacher in England. What actually governs your situation is your own employer's grievance policy, and that can vary in detail — timescales, who hears an appeal, exactly how it's structured — even though almost all share the same broad shape described above.

In practice, many maintained schools and trusts adopt a model grievance policy closely following, or directly based on, their local authority's own model, often built on template agreements historically associated with the National Joint Council for Local Government Services. In a maintained school, the legal requirement for a grievance procedure comes from regulation 7 of the School Staffing (England) Regulations 2009. An academy or trust isn't bound by that regulation directly, and is governed instead by its own policy alongside the Acas Code. Read your own employer's policy before assuming a detail applies to you.

Timescales, realistically

As with disciplinary matters, there's no fixed national deadline for how long a grievance should take overall, but real expectations attach to individual steps. The Acas Code's language is that grievances should be dealt with promptly and without unreasonable delay — deliberately not pinned to an exact number of days, because grievances vary enormously in complexity. A short, factual grievance over a single pay decision can reasonably resolve in a couple of weeks; one involving multiple witnesses and months of disputed facts will take longer.

Where you'll usually find a specific number is your own employer's written policy, which commonly sets out its own target timescales — for example, acknowledging a written grievance within five working days, or holding a hearing within a set number of weeks. These locally set figures are worth checking and holding your employer to, since the Acas Code leaves that detail to individual employers. If your grievance has stalled well beyond what your policy anticipates, that's worth raising in writing, through your union representative.

Why union support matters at every stage

A grievance raised entirely alone isn't automatically doomed — but one backed by a union representative tends to be noticeably stronger, and not only because of the statutory right to be accompanied. A representative can help you work out whether what you're describing is genuinely a grievance, help you draft a complaint that's specific and factual rather than emotive, track the timescales your employer's policy sets out, and represent you directly at the hearing.

Contacting your union as early as possible — ideally before any informal conversation, not only once a formal grievance is underway — gives a representative the best window to shape how the complaint is framed from the start, rather than rescuing a process that's already gone off track. This is one of the core services union membership is built around, at no extra cost.

If the grievance isn't resolved

Most grievances are resolved internally, often at the informal stage or after a single formal hearing. But it's worth knowing what the escalation routes actually look like if yours isn't.

The first step is the internal appeal above — worth using properly first, since a tribunal generally expects a reasonable internal process to have been exhausted. If that doesn't resolve things and you believe you may have a legal claim — most commonly discrimination or whistleblowing detriment — the next step is Acas early conciliation: free, and in most cases a legal requirement before certain tribunal claims can be submitted at all. A conciliator tries to help you and your employer reach a resolution without a hearing, and a meaningful proportion of cases settle here.

If conciliation doesn't resolve things, an employment tribunal claim is the final route for grievances engaging a genuine legal right rather than a workplace disagreement — discrimination under the Equality Act 2010 and whistleblowing detriment are the two most common categories that end up there. A claim must normally be brought within three months less one day of the act complained of, and early conciliation has to start inside that window, so it's worth diarising with your union or solicitor early. If your situation involves reporting wrongdoing rather than an ordinary grievance, our dedicated Whistleblowing Protections for Teachers guide covers the protections that apply, which differ from an ordinary grievance.

A practical checklist before you raise one

Whatever your grievance is about, a handful of practical habits make the whole process go more smoothly, almost regardless of the specific facts.

• Keep a written record as things happen, not from memory afterwards — dates, who said what, and what was agreed at each conversation, kept privately for your own reference.
• Raise concerns in writing once you move past the informal stage, so there's a clear, datable record of exactly what you said and when.
• Check your own employer's policy for its specific timescales rather than assuming a national standard exists — the Acas Code deliberately leaves exact deadlines to individual employers.
• Consider informal resolution first where it's genuinely safe and realistic to do so, but don't feel obliged to if the concern involves bullying, harassment or discrimination and going direct doesn't feel safe.
• Involve your union as early as possible, ideally before you've raised anything even informally, so a representative can help shape how the complaint is framed from the outset.
• Be specific and factual in your written grievance rather than general or emotive — specific incidents, dates and impact are far easier for an investigator to act on.
• Ask, in writing, who the right person to raise it with is if your grievance involves your own line manager or headteacher, so it goes to someone appropriately senior and independent the first time.

Finally, a brief note on scope: nothing here is legal advice, and it can't tell you whether your situation is likely to succeed as a grievance, or whether it might also amount to a legal claim. Every grievance turns on its own facts, and a general guide is never a substitute for advice from your union or an employment solicitor. If your situation has a financial dimension too, our take-home pay calculator may be a useful separate reference point.
