UK Disciplinary & Grievance Policy Template

What is a UK disciplinary and grievance policy?

Quick answer. A disciplinary and grievance policy is the written procedure an employer follows when addressing employee misconduct or capability issues (disciplinary) and when responding to employee complaints (grievance). UK policies must align with the ACAS Code of Practice on Disciplinary and Grievance Procedures — a statutory code that tribunals use as a benchmark. Failing to follow it permits awards to be uplifted by up to 25% under TULR(C)A 1992 s207A.

The disciplinary side of the policy sets out how the employer investigates and addresses concerns about an employee’s conduct or performance — what triggers an investigation, how a hearing is conducted, who decides outcomes, and what the range of possible sanctions is. The grievance side is the mirror image: how an employee raises a complaint about the employer, how it’s investigated, and how decisions are communicated and appealed.

Both procedures share the same procedural backbone: the employee must be informed of the concern in writing, given the opportunity to respond at a hearing, accompanied by a colleague or trade union representative, and given a right of appeal. These four elements are non-negotiable under the ACAS Code; their absence almost guarantees a procedural-unfairness finding at tribunal.

Who needs a disciplinary and grievance policy?

Quick answer. Every UK employer with at least one employee. There is no SME exemption: a 5-person consultancy faces the same procedural standards as a 500-person manufacturer. Particularly critical for: any employer who has ever needed to dismiss or formally discipline; SMEs preparing for fundraising due diligence; companies in regulated sectors (FCA SYSC, NHS DSP Toolkit); and any organisation handling complaints under the new Worker Protection Act 2024 sexual harassment preventative duty.

The procedural requirement starts on day one of employment. Although employees with fewer than two years’ continuous service cannot bring an ordinary unfair dismissal claim under section 108 of the Employment Rights Act 1996, they retain day-one protection against automatic unfair dismissal — for instance dismissals connected to discrimination, whistleblowing, family-friendly rights, or asserting a statutory right. A robust disciplinary procedure applied consistently from day one is the single best defence.

What must a UK disciplinary policy include?

Quick answer. Eight clauses: scope (who is covered), informal action, formal investigation procedure, hearing arrangements (with right to be accompanied per Employment Relations Act 1999 s10), range of disciplinary sanctions, gross misconduct definition with examples, appeal procedure with a different decision-maker, and record-keeping rules. Procedural fairness is the test — substantive findings can survive tribunal scrutiny if the process was followed.

• Scope and definitions — which workers are covered (employees, fixed-term staff, agency workers where applicable), what counts as misconduct vs capability, and the distinction between informal and formal action.
• Informal action — the documented option of an informal conversation before a formal procedure, with the expectation that most issues are resolved informally.
• Investigation — named investigator (usually a manager not directly involved), confidentiality expectations, suspension on full pay where appropriate, timeframes (typically 5 working days for the investigation, extended for complex cases).
• Disciplinary hearing — written notice with the allegation, supporting evidence, and the possible outcomes; right to be accompanied by a colleague or trade union representative; right to call witnesses and present a case; named decision-maker (typically a manager senior to the employee).
• Sanctions — the graduated range: verbal warning, first written warning, final written warning, dismissal. Live periods for each warning (commonly 6, 12 and 12 months). Summary dismissal reserved for gross misconduct.
• Gross misconduct — non-exhaustive list of examples (theft, violence, gross negligence, serious breach of confidentiality, working under the influence). The list anchors the summary-dismissal route legally.
• Appeal — right to appeal in writing within a defined period (typically 5 working days), to a more senior decision-maker not previously involved, with a fresh hearing or review.
• Record-keeping — what is documented (allegations, evidence, hearing notes, decision letters, appeal outcome), retention period, access rights under UK GDPR employment guidance.

What must a UK grievance policy include?

Quick answer. Six clauses mirroring the disciplinary side: how an employee raises a grievance (in writing, naming the issue), informal resolution as the first step, formal investigation, grievance hearing with the right to be accompanied, written outcome with reasoning, and a right of appeal. Critical addition for 2026: a separate route for sexual harassment complaints under the Worker Protection Act 2024 preventative duty.

The grievance procedure’s test is the same as the disciplinary procedure: was the process fair, regardless of the outcome? Tribunals scrutinise grievance handling particularly carefully when the eventual claim is constructive dismissal (employee resigned because of unaddressed mistreatment) or discrimination (employee says the grievance about discriminatory conduct was inadequately investigated). A robust written procedure, applied consistently and with audit-ready record-keeping, is the strongest evidence of an employer’s good faith.

How does this map to the ACAS Code of Practice?

Quick answer. The ACAS Code is a 22-paragraph statutory code of practice. Tribunals are required to consider it when ruling on dismissal or grievance cases. Failing to follow it without good reason permits a 25% uplift on compensation under TULR(C)A 1992 s207A. The Code is short, plain-English, and prescriptive on the procedural essentials — PolicySuite’s template is structured paragraph-by-paragraph against the Code so the procedural mapping is visible during audit.

Beyond the Code itself, the policy should also reference: the Equality Act 2010 (so disciplinary processes don’t themselves create discriminatory outcomes), the Employment Rights Act 1996 (the underlying unfair-dismissal framework), and the ICO’s employment practices guidance for handling personal data captured during investigations.
