What to do about UK work contract disputes? ACAS Mediation and Employment Arbitration Process

Last month, I was verbally informed by the company that I "don't want to come," and my salary was reduced by two weeks, and my annual leave was not discounted. The first reaction of many Chinese people in the UK when encountering this kind of thing was to endure it. Language, identity, and fear of affecting the recommendation letter for the next job make people afraid to say anything. But the UK actually has a complete dispute resolution mechanism that does not require you to hire a lawyer or pay money first. Make it clear today.

In UK work contract disputes, the first step is not to file a lawsuit, but to mediate with ACAS

In the UK, if most labor disputes (unfair dismissal, unfair deduction of wages, discrimination, etc.) want to go to the Employment Tribunal, the law forces you to contact ACAS (Advisory, Conciliation and Arbitration Service) first and go through a procedure called Early Conciliation.

This program has three features that will be extremely beneficial to you:

💷 is completely free of charge , coordinated by ACAS's neutral mediator;
🕒 No need to meet or appear in court , full phone/email communication;
📅 Starting from December 1, 2025, the mediation period can be up to 12 weeks (previously 6 weeks), giving both parties more sufficient time for negotiation.

The mediator will not judge who is right or wrong, but will help you and your former employer negotiate a mutually acceptable solution - usually a settlement. According to ACAS public data, a large number of cases are settled at this step and never reach the arbitration tribunal. This is the most cost-effective step for people who don’t want to break up and get back the money they deserve.

The deadliest pitfall: British labor arbitration has a 3-month time limit

Many people fall into the trap of "time limit". At present, the time limit for most appeals is 3 months minus 1 day from the date of incident, and ACAS must be contacted within . For example, if you are fired on April 10, in principle, you must initiate Early Conciliation before July 9. If it is one day later, the arbitral tribunal may not accept the case.

The good news is that once you notify ACAS, the clock will be "stopped" (stop the clock) . The mediation period will not be included in the time limit. If the negotiation breaks down, the time to apply for arbitration will be postponed. So procrastination is a big no-no, and the sooner you contact ACAS, the safer your rights will be.

📌 Note: According to the Employment Rights Act 2025, the time limit for most complaints is scheduled to be extended from to 6 months, which is expected to take effect around October 2026. But before it officially takes effect, please always operate according to the current "3 months minus 1 day" and don't bet on the new rules.

If mediation fails, how can we proceed to formal labor arbitration?

If the mediation fails, ACAS will issue you a EC Certificate (Mediation Certificate) with a number on it. With it, you can submit an ET1 form online to formally appeal to the tribunal.

Two key points are often ignored by the Chinese:

First, currently does not charge fees for submitting arbitration appeals. - After the Supreme Court ruled that fees were illegal in 2017, arbitration has been free of application fees, and fees have not been restored in 2026.

Second, for ordinary "unfair dismissal" complaints, the current rules require that you have been employed for for 2 consecutive years to be eligible (this threshold will be reduced to 6 months on January 1, 2027). But if your experience involves "automatic injustice" such as discrimination (race, gender, religion, etc.), whistleblowing, , etc., you will be protected on the first day of employment, and there is no length of service requirement. If Chinese are treated differently because of their accent or nationality, they can often take the path of discrimination and are not subject to the 2-year restriction.

Is arbitration worth fighting? Let’s settle this account first

Although there is no application fee for arbitration, the actual cost of hiring a lawyer is approximately £5,000–£15,000. And unlike civil courts, in arbitral tribunals "the winning party generally cannot recover attorney fees" - the fees are not automatically passed on to the other party depending on the win or loss. Therefore, for simple and small wage disputes, many people can just fill out the form and go to court by themselves, without hiring a lawyer.

In terms of compensation cap, as of 6 April 2026, the cap for compensatory damages for unfair dismissal is the lower of £123,543 or of 52 weeks’ salary before tax. The amount depends on the loss and is not a random price. If you want to quickly estimate how much you can get and how many days are left before the deadline, you can first write down the key dates and check them one by one.

If you encounter a work contract dispute, remember these 3 steps

1️⃣ Immediately retain certificates : contract, payslip, dismissal emails/text messages, working hours records, and save all screenshots;
2️⃣ Contact ACAS as soon as possible to start free mediation, don’t wait for the time limit to approach;
3️⃣ Submit an ET1 complaint again if mediation fails. If discrimination/reporting is involved, don’t be dissuaded by the "2-year threshold".
