Employment Disputes and ACAS

Josh Astle from ARAG Law explores the role of ACAS in employment disputes, breaking down what Early Conciliation involves, when it applies, and why it’s a key step before a claim reaches a tribunal.

If you’re facing an employment dispute, or think one might be heading your way, you’ll almost certainly encounter ACAS and something called Early Conciliation. For many people, it sounds formal, intimidating, or like an unnecessary hurdle before “the real legal stuff” begins.

In reality, ACAS Early Conciliation is a key part of the Employment Tribunal process and, when used well, can save time, cost, and stress. Here’s a plain‑English rundown of what it is, when it applies, and why it matters

ACAS and Early Conciliation – The Rundown

The Advisory, Conciliation and Arbitration Service (or ACAS, for those who prefer fewer syllables before coffee) is an independent public body. Before almost any Employment Tribunal claim can march its way before a Judge, it must first take a courteous detour through ACAS Early Conciliation.

What is ACAS Early Conciliation?

Think of ACAS Early Conciliation as the Employment Law version of a polite mediator - someone who steps in before things escalate to ‘full legal case mode.’ It’s a neutral service designed to help you and your employee (or employee) reach a legally binding agreement without the drama and delays of a Tribunal hearing.

There are certain situations where you don’t need to go through Early Conciliation. These are listed in s3 of the Employment Tribunals (Early Conciliation: Exemptions and Rules of Procedure) and include when someone else involved in the same dispute has already entered ACAS Early Conciliation, and the Claimant wants to hop onto the same claim form - like a ‘legal carpool’.

When should you enter ACAS Early Conciliation?

For most employment claims, a Claimant must start ACAS Early Conciliation within 3 months minus one day of the incident—be it dismissal, discrimination, or an unexpectedly empty payslip.

Both employers and workers can start ACAS Early Conciliation, though it’s usually expected that workers try resolving things internally first via these steps: complaint → grievance → appeal → ACAS.

Employers, equally, can pre‑emptively contact ACAS if they sense a Tribunal claim is looming on the horizon.

Why use ACAS Early Conciliation?

ACAS Early Conciliation is a great way to resolve matters without the stress, waiting, and emotional investment of a full Tribunal claim. It can:

If Early Conciliation is unsuccessful

Even if Early Conciliation doesn’t result in a resolution, you’ll still likely benefit from clearer issues and early discussions. Settlement negotiations can also continue after ACAS Early Conciliation ends—all the way up to the final hearing.

How to start ACAS Early Conciliation

To begin, visit: https://tell.acas.org.uk/

Scroll to “Notify ACAS online”, hit “start now,” and complete the form.

You’ll have two choices:

1. Enter conciliation

This pauses time limits for up to 12 weeks and lets the Respondent know you’re opening discussions.

2. Issue the certificate immediately

Perfect if you're ready to move straight to the Tribunal.

The other party isn’t legally required to engage with ACAS, but it’s generally wise.

Few people enjoy a two‑year wait for a tribunal list date.

If you prefer a human voice before you dive in, ACAS also offers a helpline (Mon–Fri, 8am–6pm): 0300 123 1100
